Dear customer,

you have become the owner of a Protherm Lion wall-mounted condensing boiler, designed to run on natural gas.

Please note: The boiler can be also run on propane, too, provided the requirements detailed in this Operation and Installation Guide are met.

Lion 24 KKV and 28 KKV are boilers with forced exhaust of combustion gases, intended for heating of heating water (HeW) in central heating systems and for heating domestic hot water (HoW) in a fl ow-through method. Lion 28 KKO in its basic version is intended only for heating of heating water in central heating systems. Using a kit available for this purpose, Lion 28 KKO can be extended to heat also hot water in an external tank.

We trust that the Protherm Lion condensing boiler will give you a long and satisfactory service. However, in order to achieve this, all conditions important for its safe operation must be met. Therefore please study this Guide carefully and respect all principles stated therein.

1. When installing and using the boiler, follow all manufacturer’s instructions and warnings in this Guide.

Starting the boiler up

Important: Putting the boiler into operati-on and starting it up for the fi rst time must be done by an authorised service only!

If you wish to start the boiler after it has been put into operation, make sure that:

1. the boiler is connected to power supply;2. all valves underneath the boiler (hot

water, heating water, gas) are opened;3. the heating water pressure is within the

recommended range 1,2 – 2 bar.Turn the main switch (Fig. 1, pos. 1) ON. A few moments later the heating water temperature will appear on the display and the LED under the symbol will light up (Fig. 1, pos. 2). When the burner ignites, the LED under the symbol will light up (Fig.1, pos. 6).

In the event of an emergency boiler shutdown, a fault indicating red LED will light up on the control panel (Fig. 1,

Position 5) and an error message code will appear on the boiler’s display. Unblock the boiler by pressing the RESET button (Fig.1, Position 9). If the emergency shutdown recurs after a short time again, or if the boiler cannot be RESET, call an authorised service organisation.

Turning the boiler off

Turn the main switch (Fig. 1, pos. 1) off.

If the boiler is to remain shut down for a protracted period of time, shut all valves underneath the boiler off (HeW, HoW, gas). When shutting the boiler down, take into consideration the ambient temperature in the given season. If there is a danger that the boiler may freeze, drain the water from the boiler, the heating system and the hot water pipes.

Starting the boiler up and turning it off

Boiler control

Using the boiler without room control unit

When run in this mode, the boiler maintains

the set heating water temperature. No room

control unit is connected, the terminals for its connection must be interconnected with a jumper (standard factory setting).

Setting procedure:

• turn the main switch ON;• set the heating water temperature to the

required value on the control panel.

Using the boiler with room control unit

The boiler maintains the set heating

water temperature. The room control unit connection terminal jumper must be

removed and the room control unit wired

to the terminals. The boiler is turned on

and off to maintained the set temperature in the room in which the control unit is installed. Radiators in this room must not

be equipped with thermostatic valves.

Important: You must set on the boiler

control panel a heating water temperature

(temperature of the water in the system) which will be capable of covering thermal losses of the building even in low outdoor

temperatures.

Please note: Use only control units recommended and sold by PROTHERM

which are designed and tested for the particular type of boiler. If you use a different unit, we cannot guarantee the

boiler’s correct and full functioning.

9

Using the boiler with equithermal control

The boiler changes the heating water temperature as the outdoor temperature changes.

When this type of control is used, it is necessary to install a control unit which has the equithermal control function, Protherm Thermolink B or Thermolink P. In addition, it is necessary to install an outdoor temperature sensor.

Protection against freezing

The boiler has an antifreeze protection system which protects the boiler (but not the heating and the hot water distribution systems) against freezing.

When the heating water temperature inside the boiler drops to 8°C, the pump is switched on, regardless of signal from room control unit and summer-mode setting. When the heating water temperature inside the boiler reaches 10°C, the pump is automatically switched

off. If the heating water temperature inside

the boiler continues to drop, at 5°C the boiler lights itself up and heats the heating water to 35°C.

Important: When the frost protection function is enabled, the three-way valve

switches to the middle position and both

heating water and hot water start to be heated.

Protection of hot water tank against freezing

When the temperature in hot water tank

drops to 10°C, the boiler heats the tank to

15°C. The function is enabled only when the external hot water tank with an NTC sensor is connected.

Protective functions

Pump protection

When the pump has been continuously idle for 23 hours, it is automatically switched on for about 20 seconds, to prevent it from ceasing or clogging due to protracted inactivity.

The boiler is also equipped with a clogging protection system.

Important: This boiler function cannot be disabled.

Two-speed pump

Two-speed pump with automatical switching of the speed is mouted in the boiler. When boiler warm heating water,

pump is runing according to setup of the

parameter on control board. When boiler warm hot water, pump is runing for higher speed.

Please note: Pump runing parameter may be seting up only by an authorised

technician.

Pump run-down

Pump run-down is factory set to 30

seconds for heating of hot water. When

heating a heating water, the run-down is set to 3 minutes. The maximum run-down can be set to 60 minutes.

Important: Room control unit and outdoor sensor must be installed by an authorised service only.

Setting the boiler output

The boiler is factory-set to its maximum output. If necessary, the boiler heating water output can be adjusted as required (in view of the boiler’s features).

Important: Output setting may be chan-ged only by an authorised technician.

10

Important: This boiler function is enabled only when boiler is connected to electrical mains.

Anti-cycling

The boiler features an anti-cycling function. The control board calculate automatically the delay of the next start up of boiler depending on boiler conditions.

Disconnecting the boiler from power supply

Disconnect the boiler from power supply only before service or when the boiler is to be shut down for a protracted time (see Chapter “Switching the boiler off” on page 8). When the boiler is disconnected from power supply, all protection functions are disabled.

Power failure

Power failure will turn the boiler off. When power supply is restored, the boiler will automatically restart itself without losing any of the set operating parameters.

If after power supply restoration the red

LED on the control panel (Fig. 1, pos. 5)

lights up, proceed in accordance with the

Toping up water in the heating system

Water in the heating system (in small quantities) can be topped up through the boiler’s top-up valve (Fig. 3).

When topping up water in the system, the

following conditions must be met:

1. Pressure of the water supplied to the

boiler must be always higher than the water pressure inside the heating system.

instructions in section Starting the boiler and turning if off.

Please note: The boiler may get blocked because of overheating caused by the pump being switched off as a result of the power failure. This fault can be fi xed by pressing the RESET button on the boiler’s control panel. If the fault persists, call an authorised service.

Safety valve

The boiler is equipped with a safety valve which opens when the pressure in the heating system reaches 3 bar. DO NOT TOUCH THE SAFETY VALVE! If the safety valve starts releasing heating water, always turn the boiler off, disconnect it from power supply and call an authorised service organisation. If the heating system repeatedly looses pressure, consult your service organisation.

Important: All the above-mentioned electronic protection functions are enabled only when the boiler is connected to power supply (the power cord plug is inserted into a power socket and the main switch in the ON position (I).

Service and maintenance

2. The boiler must be cold (water

temperature must not exceed 30˚C).

3. Recommended water pressure inside the cold boiler (not more than 30˚C) is 1,2 to 2 bar.

Warranty and warranty conditions

PROTHERM Lion gas boilers are covered

by warranty defi ned in the Warranty Certi-fi cate, the Service Book and other conditi-

Important: If the water mains pressure were lower or equal to the water pressure inside the heating system, the heating water may run into the water mains, which is forbidden. This danger is reduced by a built-in reverse valve installed downstream the top-up valve.

This notwithstanding, the manufacturer disclaims responsibility for any damages caused by incorrect manipulation with the top-up valve and a failure to abide by the conditions specifi ed above. Such damages and defects are not covered by the boiler’s warranty.

Procedure of topping up heating water to the boiler:

• make sure that the boiler is connected to power supply and the main switch is in the ON position;

• when the heating water pressure showed on the display is below 0.6 bar, the red LED next to the symbol on the boiler’s control panel fl ashes (Fig. 1, Position 4) and the display shows current heating water pressure.

• partially open the top-up valve (Fig. 3). Watch the pressure grow on the boiler’s

display panel;• fi ll the system up until the pressure

reaches the value between 1.2 and 2

bar;

• when the required pressure has been reached, tighten the top-up valves with your hand;

• thoroughly bleed all radiators (the water

must be running out in a continuous stream, free of air bubbles);

• check whether the pressure shown on

the display is within 1.2 and 2 bar. If necessary, add more water into the system.

Cleaning

The boiler cover can be cleaned with a moist cloth and afterwards dried and polished with a dry cloth. Never use abrasive detergents or solvents.

Important: before cleaning the boiler, turn it off with the main switch.

Regular service

To assure trouble-free and safe running of

your boiler, we recommend that you have

the boiler checked and serviced in regular yearly intervals. These inspections are not covered by the boiler’s warranty. The

operations to be done are specifi ed in the

Service Book and must be carried out by an authorised service.

Introduction

The Lion boiler is compatible with standard types of hot water heating systems and heating radiators, except systems with an open expansion vessel.

Important: Lion boilers must be put into operation by an authorised organisation only, according to Czech Bureau of Occupational Safety and Czech Mining Inspectorate Notice No. 21/1979 (in the wording of Public Notice No. 554/1990).

The boiler must be put into operation and warranty and post-warranty service performed by the manufacturer’s contracted service organisation which meets the above specifi ed requirements.

Important: The technician who puts the boiler into service must show the user all boiler functions, its controls, and if necessary explain anything the user does not understand in the User’s Guide which is part of the boiler delivery.

The boiler is designed to work in an

normal AA5/AB5 environment according

to STN 33 2000-3 and STN 33 2000-5-51 (i.e. within temperature range +5 to +40°C, humidity depending on temperature, not

exceeding 85%).

The Lion boilers are suitable for the

conditions of zones 1, 2 and 3, in rooms with a bath tub or shower and washing rooms according to STN 33 2000-7-701;

they may not be installed in zone 0 (Fig.

8). When installed in one of the above rooms, the boiler must have a protection against electric shock in accordance with

the same standard.

The boiler may be (according to Ministry

of Health Notice No. 13/1977, i.e. by their noise level) installed in habitation and

communal rooms.

The boilers are designed to run with heating water compliant with STN 07 7401 (which under no circumstances can be acidic, i.e. its pH factor must be greater than 7 and must have a minimal carbonate hardness).

Requirements on utility water properties are defi ned by STN 83 0616 (on drinking water by STN 75 7111). The reticulated water should have in accordance with the Public Notice pH factor within the range 6.5 to 9.5, and must have a minimum value of acid neutralisation capacity KNK 4.5 ≥ 1.0 mmol/l and CO2 (total) ≤ 44 mg/l.

If the water has a sum of calcium and magnesium concentration greater than 1.8 mmol/l, it is useful to implement other “non-chemical” measures against incrustation (e.g. magnetic water treatment combined with a desludging device).

Problems caused by clogging of the system with dirt from the heating system or incrustation sediments or clogging-

induced problems (e.g. clogging of the

heat exchanger, pump defects) are not cover by the boiler’s warranty.

19

Distance from fl ammable materials (e.g. PVC, chipboard, polyurethane, synthetic fi bres, rubber and other) must be suffi cient so that the surface temperature of these materials does not exceed 80°C. The safety distance for reaching this maximum temperature must be maintained regardless of the degree of combustibility of the particular material.

According to STN 06 1008, the boiler may not be located and run closer to objects (classifi ed according to STN 73 0823) than:

- 100 mm – hardly combustible, low combustible or medium combustible materials

- 200 mm – easily combustible materials (e.g. chipboard, polyurethane, polystyrene, polyethylene, light PVC, synthetic fi bres, cellulose, tar paper, rubber and similar materials)

Walls sensitive to heat such as wooden walls, must be suitably protected.

No objects made of combustible material may be placed on the boiler itself or within the safety distance (while the boiler is running), not even for a short time.

Important: Surface temperature of the boiler upper parts (particularly the side walls and the cover) of a working boiler

might exceed the ambient temperature by

up to 50°C.

The manipulation (free) space left around the boiler must be suffi cient for a person to work on it safely with bare hands and

with common hand tools. Recommended

distances are shown in Fig. 9.

Combustion gases must be removed and

fresh air supplied through a special for this purpose designed dual tubing. Practically any required dual-tube route can be

constructed from standard components

supplied by the manufacturer. The fl ue

route must be constructed in such a way that condensed water vapour contained in the combustion gases can be removed

from the tubing. This is achieved by

using special components which can be built into the fl ue route. Problems caused by condensate penetration are

not covered by the boiler’s warranty. Due

to the considerable variety of particular solutions, the dual tubing is not part of the boiler delivery and is not included in

the price. Principles for route design and

construction are described in chapter Air supply and fl ue gases removal.

Distribution pipes

Nominal pipe internal diameter is chosen in the usual way based on the pump characteristic. Distribution pipes are designed according to the requirements on system performance, not according to the boiler’s maximum output. The system must allow suffi cient fl ow so that the temperature difference between the supply and the return pipe is smaller than or equal to 20°C. Minimum fl ow must be 400 l/h.The piping system must be constructed to prevent air bubbles from developing, making permanent bleeding of the system easier. Vents should be situated on all high points of the system and on all radiators.It is recommended to install upstream the boiler a system of heating water, hot water and gas shutting valves.We recommend that you install on the lowest point of the heating system a drainage valve which will also dub as a heating system top-up valve.Before fi nal installation of the boiler, the heating distribution system pipes must be

fl ushed a few times with pressurised water.

In old, already used systems, the fl ushing must be done in opposite direction to the heating water fl ow.

Important: Before connecting the boiler to the heating system, remove the plastic

plugs inserted in all connection necks.

Heating system cleanliness

Before installing a new boiler, it is essential to clean the system thoroughly. In old

systems it is necessary to remove all

sludge settled at the bottom of the heating radiators (particularly in gravity systems).

In new systems it is necessary to remove all conservation material which majority of radiator manufacturers use.

It is recommended to install upstream the boiler (i.e. to the heating water return pipe) a sludge trap. The sludge trap should be constructed in such a way that it is easy to empty in regular time intervals without having to drain a lot of water from the heating system. The trap can be combined with a fi lter, but a fi lter with a sieve on its own will not provide suffi cient protection. The fi lter and the sludge trap must be checked and cleaned regularly.

Heating water circulation in the system

Although the boiler is equipped with a bypass, we recommend to design the heating system so that the heating water can fl ow through at least some of the radiators all the time.Please note: If the boiler is connected to underfl oor heating, we recommend to install a in the heating system a safety valve against overheating.

Using antifreeze

We do not recommend to use antifreeze, because of their unsuitable properties for the boiler. It is mainly their reduced heat

transfer, large volume expansion, aging

and, more than anything else, potential damage of the heating water heat exchangers.

Important: Defects caused by using

antifreeze are not covered by the boiler’s warranty.

Thermostatic radiator valves

If a room control unit is installed, at least

one of the radiators in the reference

room must be without a thermostatic valve. For better temperature comfort, we recommend to leave all radiators in the

reference room without a thermostatic valve.

Preparing for installation

23

Domestic hot water system

Pressure in the hot water system must be within the range of 1 to 6 bar. If the pressure exceeds 6 bar, a pressure reduction valve must be fi tted on the supply side,

combined with a safety valve.

In areas with very hard water we recommend to implement suitable measures to reduce the water hardness.

Installing the boiler

Mounting the boiler

When mounting the boiler, proceed in accordance with design documentation conditions (e.g. wall load-bearing properties, chimney inlet, pipe inlet and outlet connections). The boiler is designed for mounting on a non-combustible wall. If the boiler is to be installed on a wall which is not non-combustible, the wall must be panelled with fi re-resistant and thermally non-conductive material. When installing the boiler, applicable fi re safety regulations must be abided by. The actual installation is done as follows (Fig. 12):

Mounting procedure (Fig. 12):

1. Take the paper template provided (M) and attach it to the place of installation (W), for instance with a sticky tape. When positioning the template, use a plumb bob or spirit level.

2. Using the indicated points on the template, drill the holes required (mounting bar or connection ramp).

Important: If you are using a connection

ramp (R) – not part of standard delivery – boiler connection end pieces (T) must not be used.

3. If the combustion gases fl ue is to

penetrate through the building’s

peripheral wall, set out an opening for the concentric tubing penetration (O).

4. Remove the paper template (M).

5. Drill the required holes of diameters

indicated on the template.6. Insert wall plugs into the holes for the

mounting bar (L), and fasten the bar with

the screws provided.

7. Mount the boiler (K) on the mounting bar (L).

8. Install adapter (A) to the boiler and

tubing for combustion gases exhaust (O). Fill the space between the tubing and the wall with non-combustible

material.9. Remove plastic plugs from boiler

outlets.10. Install the sealing ring, fl ow restrictor and

protective fi lter on hot water inlet into the boiler (S).

11. Install boiler connection end pieces (T). Please note: When connection ramp (R) is not to be used.

12. Install a protective fi lter (not part of delivery) in the heating water inlet.

13. Install isolation valves (not part of delivery) on all outlets from the boiler.

14. Connect heating water and hot water and gas pipes to isolation valves.

15. Install the heating system water top-up valve lever (P).

16. Fill up the boiler (see page 10). 17. Check all joints and connections for

leaks.

Installing boiler with connection ramp

1. If you are going to use the connection ramp, proceed according to points 1 – 6 in the previous chapter “Mounting the

boiler”.

2. Assemble the connection ramp (R) as shown in the ramp installation instructions.

3. Fasten the connection ramp (R) to the

wall using the wall plugs and screws provided.

4. Install a protective fi lter (not part of

delivery) downstream the heating water

inlet isolation valve.Please note: Install another shutting valve (not part of delivery) downstream

the protective fi lter, to make maintenance

easier.

5. Connect gas, heating water and hot

water pipes.6. Remove plastic plugs and safety clips

from all shutting valves and dismount the

25

connection ramp (R) support frame.7. Install the sealing ring, fl ow restrictor

and protective fi lter (S) in the hot water inlet to the boiler.

8. Fasten the boiler (K) to the wall and

connect it to isolation valves.9. Install adapter (A) and combustion gases

exhaust tubing (O). Fill up the space between the tubing and the wall with non-combustive material.

10. Install the heating system top-up water valve lever (P).

11. Fill up the boiler (see page 10). 12. Check all joints and connections for

leaks.

Connecting the boiler to heating water, hot water and gas pipes

The boiler connection end pieces must not be subjected to any forces from the heating water, domestic hot water or gas piping system. This requires accurate positioning of all connection pipes, vertically (height) as well as the distance from the wall and mutual distance between inlets and outlets.

We recommend to design the heating system in such a way that when making repairs, it will be possibly to drain the

whole heating system from the boiler.

In case of reconstructions, in unfavourable

building dispositions, etc., it is possible to

connect the boiler to the heating system, the domestic hot water system as well as the gas supply by fl exible hoses, but only

those designed for that purpose. Flexible

components should be as short as possible, must be protected against mechanical and chemical loads and damage, and must be

replaced with new ones before the end of

their useful life cycle or reliability to meet their nominal specifi cations (as stated by their manufacturers).Please note: The manufacturer

recommends to install an external fi lter into the water inlet to the boiler.

Operating pressure in the heating system

The heating system (measured on the boiler) must be fi lled in at least to the hydraulic pressure of 1 bar (corresponds to the hydrostatic water column of 10 m). We recommend that you maintain the pressure within the range 1.2 – 2 bar. The

expansion vessel capacity is suffi cient for

up to 110 l of heating water in the heating system (at temperature 75°C).

Expansion vessel

Before fi lling the heating system up,

check pressure in the expansion vessel.

The initial pressure inside the expansion vessel should be by 0.2 bar higher than the assumed pressure in the heating

system.

If the heating system is already fi lled up, shut the heating water valves

located underneath the boiler and, using the drainage valve, relieve the boiler from pressure. Then you can check

the expansion vessel pressure and if necessary increase the pressure.

Fig. 14

Safety valve

Fig. 15

Bleeding valve

The expansion vessel pressurising valve is situated on the right from the pump (Fig. 13).

Important: Make sure that the expansion vessel capacity is suffi cient for the volume of water in the heating system (see installation design documentation).

Safety valve

The system safety valve is situated at the bottom of the boiler on the left side of the hydraulic group (Fig. 14). When the maximum pressure in the system is exceeded, water or steam can be discharged through the safety valve, therefore we recommend that you attach a hose to the safety valve neck, discharging the water into the building’s waste water system.

Important: Under no circumstances may anyone manipulate with the safety valve while the boiler is in operation. It is also forbidden to use the safety valve for draining water from the boiler or from the heating system. Problems caused by the valve being clogged with dirt from the

heating system are not covered by the boiler’s warranty.

Connecting gas supply

The Lion boilers are designed to be fuelled

by natural gas of nominal pressure in the

gas mains 2 kPa, for which the calorifi c value is most commonly stated to be within the range of 9 and 10 kWh/cu.m.

Indoor gas distribution pipes and a gas

meter must be sized adequately, taking into account also the user’s other gas appliances.

All gas distribution pipes must be installed

in accordance with STN EN 1775.

Important: We recommend to connect

the gas supply using a pipe union with the slip-over nut screwed onto the pipe over a

corresponding sealing ring (see the boiler delivery).

After completing the gas supply connection to the boiler, the coupling must be thoroughly checked for potential

gas leaks.

Toping the boiler water up

The procedure of toping up water in the

boiler is described in the part “Operating

instructions – Service/Maintenance”.

Important: Make sure that during the toping-up procedure as well as when the boiler is running, the automatic vent cap is

loosened (Fig. 15).

27

Draining water from the boiler

The drainage valve’s main function is to relieve water pressure in the boiler during repairs (Fig. 16). Water from the boiler can be drained through this valve only partial-ly.

Complete draining of water either from the boiler only or from the whole heating sys-tem and refi lling it again must be done th-rough fi ll-up (discharge) valves installed in suitable locations in the heating system.

Draining water from the heating system and refi lling it again and the follow-up operations (bleeding, adjusting expansi-on vessel) are not covered by the boiler’s warranty.

If there is a danger that hot water inside the boiler or the distribution pipes may fre-eze, measures must be implemented to dispose the water off completely.

Please note: Draining valve is situated on the boiler’s right side next to the pump (Fig. 16).

Condensate removal

It is necessary to keep removing con-

densate from the boiler all the time, and hence the boiler is equipped wit a con-densate trap, situated in its bottom secti-

on. Condensate removal hose must have

a minimum diameter 19 mm (but can be bigger).

Please note: For condensate removal can be used the hose which is part of the

boiler delivery.

Condensate must not accumulate in the removal system or in the following waste water discharge pipe – the system must

be sloping down away from the boiler all

the way, with a minimum gradient 3%.

Important: When discharging the con-

densate straight into waste water, it is essential to abide by regional or national regulations, and if necessary install a ne-utralisation device.

Cleaning the trap

The condensate removal trap must be cle-

aned regularly from sediments and dirt. The trap is removed by turning it anticloc-kwise and pulling it downwards (Fig. 17,

pos. 1).

Important: When cleaning the trap, clean

also the interconnecting hose between the trap and the combustion chamber (Fig. 17, pos. 2).

Air supply and fl ue gases removal

Method C33

Fig. 19

Fig. 18

Method C13

Combustion gasses exhaust and combustion air supply must be constructed from for this purpose designed dual tubing, which is an essential accessory to the boiler. The dual tubing is supplied as extra accessories. Because of the numerous possible topologies and components used, the specifi c route must be part of the building’s exhaust fl ue design documentation.

Horizontal tubing sections must have a gradient allowing water condensate to run towards the boiler or to special condensate removal components. This is achieved by combining elbows with straight components, which will result in a gentle slope of the straight section.

Condensate removal components should be whenever possible installed as close to the combustion gases outlet neck as possible. Defects caused by condensate penetration are not covered by the boiler’s warranty.

Air supply/combustion gases removal methods (according to STN EN 483) and permitted tube lengths

Unless stated for the following dual tube route design methods and their termination outlets otherwise, the tube lengths (from the boiler connection point to the termination outlet) must be as specifi ed in the technical specifi cations table.

Please note: As 1 Em is regarded either 1 m of straight section or one 90° elbow.

The following methods of air supply and combustion gases removal are permitted for this boiler:

Method C13

– horizontal routes with hori-zontal termination outlets discharging to free space.

When using separate tubing (80+80 mm) in horizontal routes with horizontal termination outlets, the air supply inlet

and the combustion gasses outlet from the same boiler must be situated inside a square of a 0.5 m side.

An example of a dual horizontal tubing route – method C13 (according to STN EN 483) is illustrated in Fig. 18.

Method C33

– vertical routes with vertical termination outlets into free space. For separate tubing termination outlets, the same applies as for method C13. An example of a dual vertical tubing route – method C33 (according to STN EN 483) is illustrated in Fig. 19.

Method C43

– connection to common dual chimneys. Dual tubing from each boiler

29

(individual routes) may be terminated in a common chimney; the chimney’s transportation suffi ciency is assessed from the data stated by the manufacturer of the chimney fl ue used. If the routes are terminated in the chimney in mutually perpendicular directions, the minimum vertical distance between them must be 0.45 m. If the routes are terminated in the chimney from opposite directions, the minimum vertical distance between them must be 0.6 m. Outlets of routes terminated in a common dual chimney must never be fi tted with end pieces (used in routes discharging to free space)! Both route sections (the outside – air, and the inside – combustion gases) must be safely inserted into the chimney inlet, but not too deep, so that it does not form an obstacle to the fl owing combustion gases or air.

It is essential that the tubing (chimney) of the combustion gases branch is capable to withstand temperatures up to 120°C and is suffi ciently sealed and resistant against physical and chemical effects (particularly combustion gases)

In this case the concentric tubing route must not exceed the length specifi ed in the technical specifi cations table.

Method C53

– dual tubing separated and terminated at two different points (with different specifi cations, mainly pressures).

Separate tubing can also be used to remove combustion gases and supply combustion air (see Fig. 20). The separate tubing routes must not be terminated at mutually opposite building walls.

Method C83

– tubing with the air supply part terminated in free space and the combustion gases part in a common chimney.

Air may also be taken from free space (or space with plentiful air supply) and combustion gases discharged into a common chimney (or again into a space with common presence of combustion gases). Into this method falls also the

special case detailed in the second paragraph of section Special cases – see the text below.

Method B23

– removal of combustion gases (including through separate tubing) into free space and supply of combustion air from the building’s interior in close vicinity to the boiler (in concentric tubing by interrupting the outside tube).

Method B33

– concentric tube routes removing combustion gases into a chimney and supplying combustion air from the building’s interior in close vicinity to or considerable distance from the boiler (by interrupting the outside part of the tubing).

Method B53

– tubing route constructed of components which are listed in the manufacturer’s documentation. Combustion gases tube is separate. Combustion air is supplied from within the building.

Important: Adequate quantity of air must be available to supply combustion air from the building’s interior. No other appliance may be connected to the chimney or fl ue, and at least 1.6 cu.m or air per hour per kW of boiler input must be available.

Tubing route gradient

The tubing route must be designed in such a way that the combustion removal system slopes towards the boiler, with a minimum gradient of 3%.

Separate outlet on flat wall

1. Separate outlet creates a zone from the

axis of the outlet with a width a = 0.5 m, radius b = 1.0 m and height c = 5.0 m.

Fig. 21 Diagram of formation of zone

with separate outlet of fl ue duct

2. If the axes of the outlet are at a distance

of d > 0.3 m beneath the upper part of the window construction, the created zone must not overlap with the surface

formed by the window. At a distance of <

0.3 m the zone bordered by the radius b may overlap with the upper part of the window.

Fig. 21

Examples of placing fl ue ducts according to appendix no. 7 of SR Government Regulation no. 92/1996 Coll.

Safety measures

The distance between any fl ammable material and the fl ue gas part of a separate tubing must be such that the surface temperature of this material does not exceed 80°C.

Combustion gases outlets must not be located in the following places:

• with the danger of explosion (as defi ned by STN 33 2320)

• in the building’s interior (attics, corridors, staircases, etc.)

• which can be closed, e.g. in gateway passages, etc.

• underground structures (even when they constitute no obstacle and are open), such as tunnels, subways, etc.

These principles of prohibiting combustion gases outlet locations should be reasonable applied also to the location of a separate air supply intakes.

A hole in the wall for the dual tubing for removal of combustion gases and supply of combustion air must be made with big enough clearance (120 – 150 mm) and after installation the hole must be sealed using a building technology. Sealing must be done using non-fl ammable materials (degree of fl ammability A according to STN 73 0823), such as for instance brickwork plaster, gypsum, etc. A passage through a fl ammable wall or ceiling must be treated as described in the fi rst paragraph of this section.

Important: It is prohibited to insert inside the fl ue any objects restricting the com-bustion gases fl ow (e.g. various types of exchangers to utilise residual heat). Flue is not part of the boiler delivery.

Dual outlet with horizontal arrangement on flat outside wall

The distances of the dual outlet on a fl at wall with horizontal arrangement are:

a = 1.5 m; g = 5.0 m; c = 5.0 m

In the case that g < 5 m, the zones are penetrated, in which it is necessary to adhere to a total zone width of 8 m, and proportionally increase the “a” values on both sides (e.g. g = 4.0 m then a = 2.0 m).

socket and the plug are accessible. Using various adapters, extension cords etc., is not permitted.

Important: The plug and the socket as well as a room control unit, which is an interference with the boiler’s internal wiring, must be under all circumstance connected by a qualifi ed electrician only, as defi ned by Public Notice No. 50/1978. Likewise servicing of the boiler’s electrical part must be done by a person with the above qualifi cation only. Before carrying out any works on its electrical section, the boiler must be disconnected from power supply by pulling the power cord plug from the power socket!

The main boiler section is protected by a tubular fuse (T 2 A / 250 V), situated on the boiler’s control panel – see the schematic diagrams on page 42 - 43.

Only room control units with zero-potential output may be used in conjunction with the boiler, i.e. units which feed no foreign voltage to the boiler.

Maximum load on the control unit with relay switching is 24 V / 0.1 A

The room control unit must be connected to the boiler by a two-core cable. The recommended copper wire cross-section

is between 0.5 and 1.5 sq.mm.

The room control unit connection cable must not run in parallel with power wires or cables.

The terminal box for wiring a room control unit, which is factory-fi tted with a jumper, is situated on the back of the boiler control panel.

The Lion boiler can be installed with a room control unit supporting the so called eBUS communication. For this type of control we recommend to use only Protherm Thermolink B or Thermolink P units. Only then we will be able to guarantee optimal functioning of the boiler. The room control unit cable is wired to the boiler terminal box (Fig. 25). With these units you will be able to make use of the equithermal control function. All equithermal curve settings are done through the room control unit.

Please note: To enable this type of control, an outdoor temperature sensor must be installed. The outdoor sensor cable is wired to the boiler terminal box (Fig. 25). The outdoor temperature sensor must be situated on the building’s coldest wall (usually northern side).

Important: The outdoor sensor cable and room control unit cable must not be installed in parallel with power cables (230

V power supply or similar).

42

Coupling the boiler with a tank

The boiler can run hand-in-hand with an external PROTHERM tank (B 60 Z, B 100 MS, B 100 Z, B 200 Z, etc.).

For this connection you need to buy the water tank NTC sensor

The installation must be done by appropri-ately trained service technician.

Converting the boiler to an alternative fuel (propane)

The Protherm Lion 28 (24) KKV and 28 KKO boilers are as standard made to run on natural gas. If it is required that the boiler is run on propane, it has to be con-verted for this type of fuel.

Important: The conversion must be done by an authorised technician with valid manufacturer’s certifi cate.

The authorised technician who converts the boiler to an alternative type of fuel must also make all required relevant iden-

tifi cation and secure the boiler against

unauthorised interference.
