Installation
The boiler is not designed to take the weight of the flue
system, this must be supported externally to the boiler.
▶ All horizontal flue sections must rise by at least 52mm for each metre
(3°) away from the boiler to ensure that condensate flows back into
the boiler for safe discharge via the condensate waste pipe.
▶ The horizontal terminal must be installed at 3° to ensure that the
condensate drains back to the boiler whilst also preventing rain
ingress down the air duct.
