INSTALLATION NOTES:
Ensure all flue seals are in good condition
and seated properly.
To ease assembly of flue components,
grease seals lightly with the solvent-free
grease.
Use flue clamps, where supplied, to support
the flue system.
IMPORTANT: 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 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.
A flue terminal guard must be fitted if the
flue outlet is below 2 metres from the
ground level.
