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 supplied.
Use flue clamps 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.
