PRESSURE RELIEF PIPEWORK

PRESSURE RELIEF PIPEWORK:
IMPORTANT: The pressure relief valve
is a safety device for the boiler and if
activated may discharge boiling water
steam through the relief valve drain
pipe.
Care should be taken when siting the
outlet pipe so that it does not cause an
obst ruct ion or discharge above a
window, entrance or other public access
where it could cause a hazard.
• The pressure relief drain pipe (M) from the
boiler should be at least 15mm diameter
copper pipe and run downwards away from
any electrics or other hazard, preferably to an
external drain or soakaway.
• Pipe (M) should be finished with a partial
bend, near the outlet to face the external wall
(as shown) to help prevent hazard.
