Safety valve discharge
WARNING
: It must not discharge above an entrance or window or any type of public access area.
Connect the safety valve discharge pipe to the valve, the discharge must be extended using not less than 15 mm
o.d. pipe, to discharge in a visible position outside the building, facing downward, preferably over a drain. The
pipe must have a continuous fall and be routed to a position so that any discharge of water, possibly boiling or
steam, cannot create any danger to persons, damage to property or external electrical components and wiring.
Tighten all pipe connection joints.
Gas connection
The supply from the governed meter must be of adequate size to provide a constant inlet working pressure of
20 mbar (8 in wg).
To avoid low pressure problems, it is recommended that the supply is taken to the boiler using 22 mm pipe as far
as possible.
On completion, the gas installation must be tested using the pressure drop method and purged in accordance
with the current issue of BS6891.
