CONDENSATE &

PRESSURE RELIEF PIPEWORK

CONDENSATE PIPEWORK:

•All national and, where appropriate, local regulations for the discharge and neutralisation of condensate should be followed.

•The condensate pipe must be a minimum of 21.5mmØ polypropylene pipe.

•The condensate pipework must fall at least 50mm per metre towards the outlet and should take the shortest practicable route and not exceed 3 metres outside the building. If a run greater than 3m is required, 32mmØ polypropylene pipe must be used.

•The pipework must follow one of the options shown opposite:

a - Internal waste drainage system b - Soil/vent stack

c - External drainage system

d - External condensate absorption point

•Condensate pipework must not be connected to rainwater downpipes.

•Use waterproof pipe insulation in exposed positions and for external pipework

IMPORTANT: Condensate pipework must not leak and the condensate trap must be filled with water before the boiler is started to prevent the possibility of potentially harmful flue products escaping via the condensate route.

A - Condensate from the boiler condensate trap (supplied) which has a 75mm minimum water seal.

B - Sink.

C - 21.5mm Ø polypropylene condensate pipe.

D - Gully.

E - Internal soil and vent stack.

F - 300mm x 100mm Ø sealed plastic tube.

G - Ground level.

H - Drainage holes 50mm from base of tube (12mm Ø at 25mm centres) facing away from building.

I - Limestone chippings.

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 outlet 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.

•The pressure relief drain pipe (K) should be at least 15mm diameter copper pipe and run downwards away from the boiler and discharge away from any electrics or other hazard, preferably to an external drain or soakaway.

•Pipe (K) should be finished with a partial bend, near the outlet to face the external boiler casing (as shown) to help prevent freezing.

PRE - INSTALLATION

J - External boiler casing.

K - Pressure relief pipe.
