Connecting the condensate discharge pipe

▶
Follow the instructions listed here and observe directives
and local regulations on condensate discharge.
▶
Use PVC or another material that is suitable for draining
the non-neutralised condensate.
▶
If it cannot be guaranteed that the materials the drain
lines are made from are suitable, install a system for
neutralising the condensate.
▶
Ensure that the connection between the condensate
drain pipework and the drain hose is not air-tight.
Note
The condensate drain pipework must have a
continuous fall (45 mm per metre) and should
whenever possible terminate at a suitable
drain point within the heated envelope of the
building that will remain frost free under long
periods of low external temperatures.
▶
During installation remove all burs from inside of cut pipe
work and avoid excessive adhesive which may trap small
pockets of water close to the pipe wall which can freeze
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 beware
when crossing cavities that the fall is maintained and the
pipe sleeved.
You can find further information in the "BS 6798" specific-
ation for installing and maintaining gas-fired boilers with a
nominal heat load of less than 70 kW.
