6.7 Condensation drain pipe
ATAG Condensing boilers have the top SEDBUK band A Classication for high energy
efciency in heating and domestic hot water.
All ATAG wall hung gas red condensing boilers contain a siphonic condensate trap to
collect and realease condensate.
The amount of condensate formed is determind by the type of boilers and the water
temperature produced by the boiler.
Condensate pipework.
Use plastic pipework of a diameter no less then 20 mm.
Routing of the pipework,
Wherever possible, the condensate pipework should be routed internally to prevent
freezing.
The condensate pipework must fall at least 50mm per metre towards the outlet and take
the shortest possible route
Support the pipe at least every 50 cm for near horizontal sections and 1 metre for vertical
sections
External pipework
The pipework should be kept to a minimum and the route as vertical as possible.
Do not exceed 3 metres outside the dwelling.
The condensate pipe must be run using suitable corrosion resistant materials (eg. plastic).
Terminate as close to the ground or drain as possible (below the grating and above the
water level) while still allowing for safe dispersal of the condensate.
Connection of a condensate drainage pipe to a drain may be subject to local building
controls.
Pipework subjected to extreme cold or wind chill conditions should be in a 40mm diameter
pipe.
Protect all external pipework with weather resistant insulation and, if necessary, box in,
to reduce the risk of freezing.
Making it safe.
Condensate pipework must not leak, freeze or block up.
Condensate traps must be lled before ring the boiler to prevent the possibility of potential
harmfull ue products evacuating via the condensate route.
Do not dispose condensate into a water recovery system where it is recaimed for reuse.
Condensate can be discharged into a rainwater hopper which is part of a sewer carrying
both rain water and foul water.
