4.2 InstallatIon - Condensate dIsPosal
Firebird condensing boilers, when in condensing mode, extract more heat from the flue products and the resulting
condensate which is mildly acidic, needs to be drained from the boiler via a condensate pipe to the drainage system.
Provision must be made for the removal of condensate from the boiler to an internal soil stack, waste pipe,
external soil stack, gully or soak-away, as per Bs 6798: 2014.
The condensate trap is provided with the boiler and situated on the front of the boiler (under the cleaning door). This
should be checked at regular intervals and cleaned during annual service.
The condensate line should:
• be plastic and have a minimum diameter of 22mm dia.;
• have a fall from the boiler of 1:200 minimum;
• have as few bends as possible to reduce the risk of trapping condensate.
Copper or steel cannot be used.

Before switching on your
Firebird condensing oil boiler
check that:
(1) The condensate drain
baffle is in place.
(2) That the condensate trap
is primed.
(3) The condensate discharge
pipe is a corrosion
resistant pipe.
