INSTALLATION NOTES:
When connecting a flue elbow directly to
the boiler flue outlet, loosen the flue elbow
retaining bracket screws (N) before fitting
the flue elbow. Insert the flue elbow with its
clamp loosely fitted, then tighten the bracket
screws (N). Clamp the elbow when
adjusted to its required orientation.
If using an extension or horizontal terminal
onto the boiler flue outlet, remove the flue
elbow retaining bracket (M).
3°
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.
Bracket (M)
All horizontal flue sections must rise by at
least 52mm for each metre away from the
Screw (N)
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
* To use the flue outlet 'B' the expansion vessel
must be removed and the connection from the
boiler capped off. The expansion vessel must be
fitted outside the boiler and connected to the
right hand side 1" BSP tappings (T).
