USERINSTRUCTIONSDualThermostat The radiator temperature is regulated via the boiler control thermostat. The thermostat is user adjustable from 55C at its minimum setting (dial 0) to 85C at its maximum setting (dial 5). In order to provide an additional level of safety there is a high limit thermostat which has a cut off point of 0C; this is factory set and is not adjustable. If thermostat trips it needs to be reset manually. HighLimitThermostatReset If the high level thermostat trip has operated, remove the reset cover by using a coin or screwdriver (turning anti clockwise) and press the small red button now exposed. Do not press the reset button while the boiler is still hot as this will cause damage to the thermostat.ControlThermostat

Reset

BurnerLockout When the pressure jet oil fired burner stops after failing to fire the red reset button will be illuminated. This indicates that there is a fault or there is no fuel getting to the burner. The house holder should only reset the burner twice in succession. If the burner continues to lockout contact Warmflow or your service engineer. SystemPressureSystem&CombiBoilers When the boiler is connected to a sealed system the system pressure should be periodically checked. The minimum pressure, as indicated by the black needle, is 0.5 bar when the boiler is cold and 2.5 bar when the boiler is at normal operating temperature. If the pressure is outside this range contact Warmflow or your installer.BurnerLockOutReset

FillingLoop If the system pressure falls below the minimum (eg, removal of radiator for decorating purposes) then the system should be topped up using the filling loop valve. After the system has been topped up the pressure gauge should read bar when the system is cold. The valve must be fully closed and the filling loop flexible removed from the valve, expect a small water loss from the pipe. CombiControlPanel The heating control thermostat is user adjustable from 55C to 85C. In order to provide an additional level of safety there is a high limit thermostat which has a cut off point of 0C; HighLimit this is factory set and is not adjustable. The high ResetButton Underneath limit thermostat is located under the control panel to the left hand side, press button to reset. As standard the panel is fitted with two on/off selector switches to control hot water and central heating. These switches can be replaced by the optional two channel digital programmer, instructions for use are provided in the main boiler handbook.ControlThermostatKnob

CONDENSINGBOILERINSTALLATION REQUIREMENTSThe Warmflow condensing boiler can be fitted to most installations using standard practices and techniques. There are however a number of considerations that must be taken into account. . All existing systems must be properly flushed to remove any sediment/ sludge in order to prevent any blockage or reduction in efficiency of the boiler. The system must be fully pumped. The primary difference between an ordinary boiler and a condensing boiler is the condensate drain. The drain can be plumbed from the condensate trap in any ordinary plastic pipe, eg, plastic overflow pipe, directly into the household drain or soak away. Any blockage in the drain could lead to an alteration in the combustion settings because of partially blocked flueways. Where the boiler is fitted into a basement a condensate pump may be required. 4. As an indicator of the increased efficiency of a condensing boiler there may be a visible plume of steam from the flue. Care needs to be exercised when positioning the appliance and selecting the type of flue to ensure that the plume does not cause a nuisance to the householder or to surrounding properties. As the water temperature in the system rises the pluming effect will diminish. Even where pluming is not visible the boiler is still operating more efficiently than a standard boiler.

BEFOREFITTINGACOMBIBOILER THEINSTALLERMUSTCHECK:. What the maximum hot water demand is likely to be placed on the boiler. Not every installation is suitable for a Combi boiler. Systems requiring very high hot water flow rates may be better suited with an unvented cylinder. That the mains are capable of supplying up to 24 litre/min with a minimum dynamic pressure of .8 bar at the boiler. This is to ensure that the boiler can achieve its maximum output. To prevent excessive flow rates ie greater than 24 litre/min it is recommended that a pressure reducing valve is fitted to the incoming mains water supply, set at 2 bar. Where the mains water pressure is supplied via a borehole pump and accumulator the pressure variation must not affect the thermostatic mixer valve. (Contact Warmflow for further details). The hardness of the mains water supply. Systems with hard water must be fitted with a suitable chemical scale preventer (eg Fernox Quantomat or Combimate alternatively contact Warmflow for further details). That the flow from any one hot water outlet does not exceed the maximum recommended. This applies particularly to baths which are usually fitted with larger taps and larger bore supply pipes. It may be necessary to restrict the flow to these taps by reducing the bore of the supply pipework (eg 5mm) or by fitting a restrictor into the pipework. That any outlet when opened does not starve all the other outlets of hot water. If more than one outlet is open at the same time then the total flow from all the outlets should not exceed the maximum flow rate of the boiler. That any showers being supplied with hot water by the boiler are compatible with this type of appliance (contact Warmflow for further details). It should be noted that the boiler has been factory fitted with an 8 litre/min flow restrictor. The manufacturers guarantees are void if the appliance is not installed and commissioned in accordance with the recommendations made herein.Page 5

GeneralInformation Introduction Note: All our domestic appliances have been independently tested and accreditedasexceedingtheminimumSEDBUKefficiencylevelsrequiredfor its type, in compliance with the Building Regulations Approved Document L1A, L1B for England and Wales, the Building Standards (Scotland) Regulations Section 6, Part F northern Ireland and Part L Republic of Ireland. Warmflow oil fired condensing boilers are designed to burn Class C2 (28 sec redwood) kerosine and to be used on a fully pumped system, and are suitable for connection to sealed heating systems. As standard the Combi and System boilers are fitted with a system expansion vessel, circulating pumps, filling loop, pressure gauge and safety valve. An optional 7-day electronic programmer kit is also available. The Combi can provide at mains pressure domestic hot water without the need for a storage cylinder. Themanufacturersguaranteesarevoidiftheapplianceisnotinstalledand commissionedinaccordancewiththerecommendationsmadeherein.

1.2

GeneralRequirements The installation of the boiler must be in accordance with the following regulations. BS540 : PART Code of practice for oil firing. BS5449 : PART Forced circulation hot water systems. BS7593 : Treatment of water in domestic hot water central heating systems. Current Building Regulations: Part J England and Wales Section 3 Scotland Part L Northern Ireland Part J Republic of Ireland Current IEE Regulations: BS7074 : PART Application Selection & Installation of Expansion Vessels The heating system should be installed by a competent installer in accordance with the recommendations laid down by HVCA, OFTEC and a sound engineering practice. In order to comply with GB building regulations OFTEC forms CD10 for installationsandCD11forcommissioningshouldbeleftwiththecustomer, alternatively the installation can be inspected and approved by a building control officer. CD10 and CD11 forms are available from OFTEC on Tel:08456585080,Fax:08456585181. Page 6

1.3

CombiGeneralRequirements The boiler will have a DHW priority when both domestic hot water (DHW) and central heating (CH) are selected. So if the flow switch is closed or the heat store has not been satisfied the entire output of the boiler is directed to DHW before the boiler will switch over to CH. When fully cold it can take up to 20 minutes for the heat store to be satisfied. After a draw-off of 20L at 24L/min, with an average temperature rise of 32C, the thermal store has a recovery time of approximately 7 mins. Note: If HW has not been selected no hot water can be produced even if the heat store is up to temperature.

1.3.1 PumpOver-Run Where there is a build up of excess heat in the boiler primary heat exchanger and the central heating has not been selected then the pump over-run thermostat will operate. The excess heat will then be pumped into the heat store. Once the temperature has fallen in the boiler and the pump over-run stat is satisfied or the central heating pump starts to operate, then the hot water pump will stop. 1.4 BafflePositioning

Before firing make sure the baffles have not been dislodged in transit. To achieve maximum efficiency push the primary heat exchanger baffles in the direction of the arrows as shown. The secondary heat exchanger spring baffles must be fully inserted into the heat exchanger tubes (narrow end first). Page 7

CondensateDisposal The Warmflow high efficiency condensing boiler is supplied with a factory fitted, self sealing condensate trap. The trap has been fitted inside the boiler casings to the right hand side. The condensate drainage pipe within the boiler is a flexible plastic hose which can be trimmed to length. 3/4 or 22mm pipe should be connected to the flexible hose. The pipe should not be made from steel or copper. The drainage pipe may run into an internal soil stack or waste pipe, an external gulley, hopper or soakaway as shown below. The boiler when fully condensing will produce a maximum of .5 litres per hour of condensate. It is recommended that the drainage pipe should have a minimum fall of :20.

OilSupply Oil Tank Steel tanks constructed to BS799 : PART 5 should be painted on the outside only and mounted on piers to prevent corrosion. Plastic oil tanks are also available and can be suitable for installation at ground level. However, oil should never be stored in translucent plastic containers. The tank outlet should be at a height to provide sufficient clearance to allow for proper maintenance of any isolation valve oil filter or water separator fitted.

2.

The pipe from the oil tank to the burner should be run in copper, steel or aluminium. Galvanised pipe and fittings should not be used. The pipework should terminate close to the boiler and be fitted with an isolating valve and filter. It is also recommended that a remote sensing fire valve should be fitted to the oil line preferably before the oil line enters the building (BS540 : PART ). Depending on the position of the tank a two pipe system may be required. One and two pipe oil systems are shown below. As an alternative to a two pipe system a Tigerloop or other approved de-aerator. may be used.

5.1.1 InstallationofaBalancedFlue . Make a suitable sized hole in the wall or ceiling for the flue kit. Add the dimensions given in section 2 as required. The cavities around the opening must be sealed and protected by a non-combustable sleeve. Remove the top panel. Break out the required knock out piece in the casing panel for the flue. Carefully fit the inner and out seals to the flue adaptor. After fitting the seals to the flue smear them with the lubricant supplied. Place the gasket correctly on the boiler and locate the flue adaptor over this, fixing it in position using the nuts and bolts provided. For the low level flue side outlet options on white case boilers it will be necessary to manoeuvre the adaptor through the side panel before fixing it to the boiler after the blanking plate has been removed. Push boiler into position against the wall. If fitting extension pieces or bends ensure the seals are correctly fitted and lubricated before pushing through the wall and attaching to the flue adaptor. Slide the flue terminal into position with a twisting movement ensuring that it protrudes through the wall by a minimum of 75mm and a maximum of 225mm or through the roof by a minimum of 665mm. Seal the gap between the flue and the wall both inside and out after which the protective basket must be fitted to the wall over the flue terminal. After removing the air inlet cover fit the air intake adaptor spigot and gasket to the burner. Connect one end of the air duct to the flue and the other end to the air intake spigot on the burner. Both ends should be securely fastened with the jubilee clips. The boiler is now ready to be connected to the plumbing, oil supply and mains electricity. The side casings of the boilers have been designed with knockouts to allow the oil pipe and electric cable to pass unnoticed inside the unit. Note: Where a knockout has been removed ensure that a grommet or cable gland is fitted to the hole prior to passing any cable through it. 2. A test hole for commissioning purposes has been provided on the secondary heat exchanger door.

ConventionalFlues The flue should be designed in accordance with the local bye-laws and the Clean Air Act. Draught stabilisers are not recommended for oil fired boilers. Sharp bends or horizontal runs should be avoided and the flue should terminate 2 feet (600mm) above the ridge of the dwelling. Terminals which restrict the discharge or allow ingress of water should be avoided. When connecting to an existing masonry chimney a flexible stainless steel liner of the correct diameter must be used. The annular space must be filled with insulation and sealed top and bottom. The starter piece should be sealed into the conventional flue adaptor using a high temperature silicone sealant, fire cement must not be used. Only flues suitable for use with oil fired condensing boilers must be used.

. 2. 3. 4. 5. 6. 7. 8.

The flue should not discharge beneath opening windows or within 2 metres of other accesses to the building. The flue should not discharge near internal/external corners of the building where turbulent wind conditions could occur. A terminal guard must be fitted at all times. The terminal should not discharge over property boundaries. Discharge into narrow passageways should be avoided. The actual siting of the flue should be determined by the installer after consultation with the householder. In positioning the flue the wind direction should be considered. Account must be made of the pluming from the flue. If it is likely to be a nuisance to the householder the use of a vertical balanced flue or conventional flue should be considered.

InstallationRequirements The boiler installation must be in compliance with BS540 : PART and the Building Regulations.

7.1

GeneralRequirements

7.1.1 Hearth The boiler hearth temperature is between 50C and 85C and should be stood on a rigid, non-porous, non-combustible base, which is not softened by warmth, to comply with the Building Regulations. 7.1.2 ServiceAccess 24 (600mm) Clearance should be provided above and in front of the boiler to allow for routine servicing. 7.1.3 HeatingSystem The heating system should be installed to HVCA current codes of practice. Before installing the boiler the new or existing system should be thoroughly flushed to clear all sludge or other foreign matter such as solder, steel wool and copper fillings. We recommend that the system is cleaned out in accordance with BS5449 and BS7593 using a suitable non-corrosive commission cleanser. It is further recommended that a suitable corrosion inhibitor is added to the heating system, which will not damage the synthetic rubber parts within the boiler. 7.1.4 AirVents In addition to any factory fitted air vents it is recommended that another air vent is fitted at the highest point in the system. Where the flow pipework drops down from the boiler the installer must ensure that an automatic air vent is fitted to the top of the pipework to prevent air being trapped in the boiler. 7.1.5 DrainCock Drain cock(s) should be fitted to a bottom connection on the boiler and to the lowest points in the system to enable the system to be fully drained. 7.1.6 FrostProtection Where there is a risk to the boiler or installation from frost then a suitable frost thermostat should be fitted. Alternatively the system could be dosed with an anti freeze agent. The Kabin Pak Combi boiler is factory fitted with a frost thermostat as standard. 7.1.7 BoilerConnections All connections to the appliance should be made with compression fittings, with the last 600mm of the primary flow and return pipework made from copper.

7.2.1 ExpansionVessel A 2 litre expansion vessel charged to 0.5 bar is supplied with both the system and Combi boiler. This can accommodate a maximum combined boiler and system volume of approximately 50 litres. If this volume is exceeded an additional vessel will be required. Refer to BS7074: PART or BS5449 for details of sizing. The values given in the table are for total system values which includes the primary water capacity.

TOTALSYSTEM VOLUME

The pressure in the vessel(s) should be checked annually during the normal boiler service by fitting a gauge to the schrader valve on the vessel. Ensure the system pressure is at zero to ensure an accurate reading. 7.2.2 SystemFilling As standard, a filling point complete with a filling loop has been included within the appliance. The temporary hose must be disconnected after filling. A system pressure when cold of bar is recommended. After filling, vent all air from the system. Ensure the caps on the automatic air vents are loose or removed and bleed both circulating pumps. 7.2.3 SystemPressure Water loss from the system as indicated by a reduction in pressure on the pressure gauge may be made up through the filling loop. In the first week of operation it is normal to see a drop in system pressure. After this time the system pressure must be rechecked and the system refilled. Failure to do so may lead to boiler faults. 7.2.4 PressureReliefValve Any pressure relief valve fitted to the boiler or system must be able to discharge externally to a drain where the discharge can be seen but cannot cause any injury or damage. No other valves should be positioned between the relief valve and discharge termination. 7.2.5 LowPressureSwitch Where there is a catastrophic loss of water from the system the boiler thermostats may fail to operate which would result in serious damage to the appliance. To prevent this it is recommended that a low pressure cut out switch set at 0.2 bar is fitted to thesystem and wired in series with the boiler limit thermostat (see page 6).

7.3

CombiDomesticHotWater

7.3.1 MainsWaterPressure To reduce the likelihood of leaking joints the mains water supply pressure must not exceed the factory test pressure of 5 bar. If the mains water pressure exceeds 2 bar then a pressure reducing valve must be fitted. The final 600mm of the mains supply pipe to the appliance must be in copper. The flow rate of water from individual taps is dependant on the number of outlets being operated together, as well as the length and size of pipework in the system and the mains supply pressure. Whenever a pressure reducing valve or any other device containing a non-return valve is fitted to the mains water supply pipe entering the boiler, it is recommended that a mini expansion vessel, suitable for use on potable water, is fitted between the device and the closed tap. 7.3.2 WaterHardness Although many of the DHW components are designed to resist lime scale formation, in areas of hard water it may still be necessary to fit an inline chemical water softener. For further information contact Warmflow and your local water company. 7.3.3 HotWaterPumpedReturn To ensure economic use, the pipe runs between the boiler and the taps should be as short as possible and insulated to reduce heat loss. For boilers that have to be sited remotely from the main point of use, there is likely to be very long pipe runs which can lead to excessive water usage and poor fuel efficiency. It is recommended that a pumped hot water return is used in order to improve HW reaction times. Contact Warmflow for details. 7.3.4 FlowRestrictor An 8L/min flow restrictor has been factory fitted but can be easily removed if required.FLOWSWITCH FLOWRESTRICTOR WASHER

7.3.5 Boreholes Where the mains water supply to the boiler is fed from a borehole via a pump and accumulator arrangement the variable pressure can cause the mixer valve to go to its fail safe settings thus preventing the outlet water temperature from achieving a suitable level. In order to minimise the pressure variations it is recommended that differential on the borehole pump pressure switch is kept as low as possible without adversely affecting the pump motor. The accumulator must be as large as possible in order to reduce the rate of pressure change and a pressure reducing valve (PRV) must be situated between the pump and accumulator and the boiler. The PRV must be set slightly below the minimum setting of the pressure switch on the pump. Page 49

AirDamperAdjustment The air damper is set in factory. This regulation is purely indicative. Each installation however, has its own unpredictable working conditions: actual nozzle output; positive or negative pressure in the combustion-chamber, the need of excess air, etc. All these conditions may require a different air damper setting.AirDamper(A)15/21BurnerOnly AirDamper(B)

Air Damper (A) The main air damper can be set in either of two positions. To set the positions of the damper, proceed as follows: Remove the secondary air damper (B) loosening the screws (). Loosen the screw (2) and rotate the main air damper (A) to the required position. Retighten the screw (2) and put back the secondary air damper (B).

Air Damper (B) The purpose of this damper is to perform a finetuning of the inlet air. Tuning of this device is possible by turning the screw (3).

Commissioning&Servicing Commissioning

Note:It is the responsibility of the installer to ensure that the boiler is properly commissionedbyanOFTECtrainedandregisteredtechnician.Failuretodo soWILLinvalidateALLwarranties. Combustion tests must be carried out using a Combustion Analyser. The pump pressure can be checked by fitting a manifold and a pressure gauge to the oil pump. Before firing ensure that all the baffles are in place as they may have been displaced during transit as shown on page 7. Switch the boiler on, ensuring all controls are calling for heat. Typical burner settings and test data are shown in section 2.5. Check the smoke reading, CO2 content and flue gas temperature with the boiler up to temperature. Testing while the boiler is still relatively cold gives inaccurate results and leads to incorrect adjustments being made. Where a balanced flue has been fitted ensure the air duct connecting the flue and burner has been properly connected before commissioning. To comply with GB building regulations OFTEC form CD should be completed and a copy left with the householder. 9.2 Servicing

9.2.1 GeneralRequirements It is recommended that the appliance is serviced annually by a Warmflow or an OFTEC registered service technician in accordance with the recommendations laid out in OFTECs technical information book 2 Pressure Jet Appliances Commissioning Requirements for Technicians. Additionally when servicing special attention should be paid to the condition of the oil nozzle, flexible oil line, fuel filter, door insulation, sealing rope and secondary heat exchanger door seal, if found defective they must be replaced. Note:Secondyearorotherextendedwarrantieswillbeinvalidatediftheappliance is not serviced annually by a Warmflow or OFTEC trained and registered technician.
