This minimises the risk of the dis-charge pipe freezing up.7dSoakawayc65GulleyaInternalstackpipe343bInternaldischarge system11236.4 Condensate discharge pipework> Connect the condensate discharge (1) of the boiler to acondensate discharge pipework (3) which has a minimuminternal diameter of 19 mm (22 mm outside diameter forall external pipes) and is made from an acid-resistantmaterial (e.g. plastic overflow pipe).i The condensate discharge pipework must have acontinuous fall (45 mm per metre) and shouldwhenever possible terminate at a suitable dis-charge point within the heated envelope of thebuilding that will remain frost free under longperiods of low external temperatures.> During installation remove all burs from inside of cutpipe work and avoid excessive adhesive which may trapsmall pockets of water close to the pipe wall which canfreeze and build into a larger ice plug.> As with other pipe work insulate the condensate dis-charge pipe to minimise any risk of freezing and bewarewhen crossing cavities that the fall is maintained and thepipe sleeved.> The condensate discharge pipework must terminate in asuitable location.Further information can be obtained from "BS 6798 Specifi-cation for installation of gas–fired boilers of rated input notexceeding 70 kW net". The condensate siphon (2) must befilled with water as described in the relevant section beforethe boiler is commissioned.6.7 Connecting the discharge pipe to theexpansion relief valve on the boilerThe expansion relief valve for the heating installation isintegrated in the boiler.> Install the discharge pipe for the expansion relief valveso that it does not interfere with the removal and fittingof the siphon trap.i We recommend not to shorten the dischargepipe supplied.> Leave an installation space of at least 180 mm beneaththe condensate siphon.min.1801236.5 Fitting the discharge pipe to the expansion relief valve(example: VUW boiler)> Insert a seal (1) in the cap nut (2).> Screw the discharge pipe (3) onto the expansion reliefvalve.> Make the discharge line routing as short as possible andsloping away from the boiler.> Allow the line to terminate in such a way that nobodycan be injured and no cable or other electrical compo-nents can be damaged if water or steam is ejected.> Please note that the end of the line must be visible.
