GAS CONNECTION
INSTALLATION
1. Open vent and cold feed connections must be made
to the boiler flow and return tappings according to
the options shown in Frame 6.
2. The boiler is assumed to be the highest point of the
circulating system.
3. The circulating pump is positioned on the FLOW
and the vertical distance, between the pump and
feed/ expansion tank, must comply with the pump
manufacturer's minimum requirements, to avoid
cavitation. Should these conditions not apply, either
lower the pump position or raise the feed/ expansion
tank above the minimum requirements of Caradon
Plumbing Limited.
4. The water velocity through the boiler flow / return
pipes is assumed to be below 1 m/s (3 ft./s), whilst
the pump flow rate is set to provide a temperature
difference of 11
o
C (20
o
F) across the boiler flow /
return, at design input.
5. This information is intended as a GUlDE ONLY and
cannot take into account instantaneous changes in
head caused by the operation of motorised valves,
pumps etc.
Due allowance MUST be made if surging is liable to
occur.

20 mbar (8 in.w.g.) MUST be available
at the boiler inlet, with the boiler
operating.
2. Extend a gas supply pipe NOT LESS
THAN 15mm (
1/2") OD to the boiler and
connect to the gas cock situated at the
front LH side of the boiler.
3. Test the gas installation for soundness
and purge in accordance with BS.6891:
1988. Refer to Frame 24.

Btu/h) then 28mm (1") pumped flow and return pipes
should be used, both to and from the boiler.
Gravity connections MUST be at least 28mm (1").
