WATER SYSTEMS amp PIPEWORK

PLASTIC PIPEWORK

o Any plastic pipework must have a polymeric

barrier with 600 mm (minimum) length of

copper or steel pipe connected to the boiler

o Plastic pipework used for underfloor heating

must be correctly controlled with a thermoshy

static blending valve limiting the temperature

of the circuits to approx 50middotC

The pipework from the boiler to the blending

valve must be in copper or steel (protected

from corrosion)

CONNECTIONSNALVES

o All system connections taps and mixing

valves must be capable of sustaining a presshy

sure up to 3 bar

o Radiator valves should conform to

BS276710

o All other valves should conform to BS1010

o On new installations or extensions to existshy

ing systems where a radiator previously did

not exist each radiator should be fitted with

a TRV except the one fitled in the same

roomarea as the rocm thermostat

o On boiler only replacement jobs it is recomshy

mended (but not mandatory) to fit a TRV on

each radiator It is however a requirement

for energy conservation purposes to recomshy

mend to the customer that a TRV is fitted to

each radiator

o An automatic bypass may be required

(downstream of the pump) in order to mainshy

tain the minimum flow-rate through the applishy

ance

o A drain cock is required at the lowest point

on the system

bull An air vent is required at the highest point

on the system

SHOWERSBIDETS

o If a shower head can be immersed in water

or comes closer than 25 mm from the top

edge of a bath or shower tray spillover level

then an anti-siphon device must be fitted to

the shower hose

bull Bidets with direct hot amp cold mains water

can be used (with the approval of the local

water authority) and must be the over rim

flushing type with shrouded outlets to preshy

vent the fitting of hand held sprays

SEALED PRIMARY SYSTEM

bull The pipework must follow one of the oplions

shown opposile into an internal serviceable

trap (min 75 mm) such as a sinkwashing

machine) and discharge direct into a vent stack

(E) min 450 mm above pipe inver or into a gulshy

ley (O) below ground bul above the water level

bull Wherever possible the condensate disshy

charge pipe work should be routed and tershy

minated internally Should this not be possishy

ble and the only available route is external

the following conditions should be

observed

Pipe work length should be kept to a

minimum and the route as vertical as

possible

Where pipe work could be subjected to

extreme cold or wind chill a weather

proof insulation should be used

Altematively the condensate pipework

could be increased to a minimum 32 mm

without the requirement 10 insulate

IMPORTANT Ensure there are no blockshyages in the pipe run

PRESSURE RELIEF PIPEWORK

IMPORTANT The pressure relief valve is a safety device for the boiler and if activated may discharge boiling water or steam through the relief valve drain pipe Care should be taken when siting the outshylet pipe so that it does not cause an obstruction or discharge above a window entrance or other public access where it could cause a hazard

bull The pressure relief drain pipe (MO) from

the boiler should be at least 15 mm diameter

copper pipe and run downwards away from

any electrics or other hazard preferably to

an external drain or soakaway

bull Pipe (M) should be finished with a partial

bend near the outlet to face the external

wall (as shown) to help prevent freezing

bull Use waterproof pipe insulation in exposed

positions and for external pipework

bull The flue must not cause an obstruction

bull Discharge and any noise from the flue outlet

must not cause a nuisance

bull Flue gases have a tendency to plume and in

certain weather conditions a white plume of

condensation will be discharged from the

flue outlet Where this could be a nuisance

for example near security lighting an altershy

nate position should be found

bull The air inletoutlet duct and the terminal of

the boiler must not be closer than 25mm to

any combustible material

Detailed recommendations on protection of

combustible materials are given in

BS 54401

bull A protective terminal guard must be fitted if the terminal is 2m or less above a surface to

which people have access

The guard must be spaced equally (minishy

mum 50 mm) around the flue and fixed to

the wall with plated screws See Contact

Information (inside front cover)

In addition the terminal should not be nearer than 150mm (fanned draught) to an opening

in the building fabric formed for the purpose of accommodating a built-in element such as a

window frame
