Installation & Servicing
For flue lengths greater than 600mm, refer
to Frames 32 & 33 - Flue extension ducts.
Flue assembly
23 FITTING THE FOAM SEAL
1.
To determine the position for the foam seal measure the
wall thickness and mark it onto the flue, measuring from
the groove near the terminal.
2.
Wrap the self-adhesive foam strip round the flue,
ensuring that the foam is on the terminal side of the line.
This seals the gap between the flue and the wall.
INSTALLATION
22 CUTTING THE FLUE
For flue lengths 114 to 600mm ONLY
1.
Measure the flue length required (i.e. the distance from
the side of the boiler to the outside face of the wall).
Refer to Frame 9.
2.
Mark the flue length required onto the flue, measuring
from the groove near the terminal.
3.
To ensure the tube is cut square, mark the flue all the
way round.
4.
Insert the cardboard duct ring for support and cut to
length.
5.
Remove cardboard duct ring and remove any burrs.
24 FITTING BOILER SEALING RING
TO THE FLUE
1.
Fit the boiler sealing ring inside the outer flue duct.
Ensure the boiler sealing ring is fully engaged.
Ensure the notch aligns with the groove on the outer flue
duct. This ensures correct alignment of the flue terminal.
2.
Drill 3 holes 3.2mm (
1/8
") dia. through the outer flue duct
and boiler sealing ring.
Do not drill the inner flue duct
.
3.
Insert the self tapping screws, provided, in order to fix the
boiler sealing ring in position.
25 FITTING THE FLUE ASSEMBLY
1.
Insert the flue assembly through the hole far enough to
allow the rubber seal to unfold completely and form an
adequate seal on the outside wall. This will also ensure
the correct alignment of the flue terminal.
2.
Ensure the notch is at the top. This will aid the location of
the studs into the boiler back panel.
