Aluminium flue pipe must not be used on this appliance as it may lead to premature failure of the
heat exchanger and will invalidate the warranty.
CONDENSATE DRAIN
Condensate can flow back to the appliance, this will travel through the heat exchanger into the condensate drain via the trap.
If the flue system rises at an angle of at least 3 (50mm per metre), no additional condensate drain will be required. Failure to provide an
adequate rise in the flue system may lead to pooling of condensate which may lead to premature failure of the flue system.
