10 Telescopic Flue - Length, Preparation and Installation
10.4 SIDE Flue
With the flue elbow temporarily fitted, measure the distance
from the outside wall to the butt joint, see diagram 10.6. If the
measurement ‘Y’ exceeds 525mm, then the appropriate length
of extension pipe is required.
If the dimension is less than 315mm DO NOT cut the flue, it
can project to a maximum of 600mm, refer to diagram 10.5. If
this is not desirable then a Standard flue MUST be used and
cut to length.
10.5 Flue Fitting
IMPORTANT:-
The flue seals are sensitive to mineral oil based lubricants. Do
not grease the seals. If the seals do need to be lubricated
use only water.
During the installation of the flue system, ensure that debris
such as mortar, filings or swarf are cleared from the flue
system before completion.
Inspect the flue pipes before fitting and do not install damaged
or dented flue components.
When assembling the flue system, ensure that the inner
seals are not damaged, do not install a flue component with a
damaged seal.
When fitting flue elbows ensure that they are fitted at the
correct angle to avoid strain, this will ensure that the seal fits
correctly preventing leakage.
With the air duct seams aligned and the flue set to the
required length ‘Y’, mark the securing hole position in the air
duct. Drill a 3mm diameter hole at this position, take care not
to pierce the inner flue duct. Secure with screw provided and
tape the joint, see diagram 10.7.
Fit the sealing collar onto the locating ring on the flue terminal,
see diagram 10.8.
With the flue elbow removed, push the flue assembly into
the wall, externally or internally, until the end of the assembly
protrudes a short way from the inside face of the wall. This
will enable the internal trim ring (if required) to be positioned
and allow the flue assembly to be drawn back up to the flue
elbow.
Secure the flue elbow in position on top of the boiler with the
four screws supplied.
Draw the flue assembly from wall and engage the flue duct
into the elbow and butt fit between the air duct and flue elbow.
Fit the securing collar into position.
Ensuring correct alignment of the flue, mark through two of the
pre drilled holes in the securing collar.
Remove securing collar and drill two 3mm diameter holes one
in the elbow and one in the air duct, take care not to pierce the
inner flue duct. Fit the securing collar and secure with screws
provided, see diagram 10.9.
Slide the internal trim ring back against the wall, securing in
place with a small amount of sealant if required.
The cut ducts must be de-burred and all filings and debris
removed.
Insert the flue duct into the air duct terminal assembly,
remembering to engage the catch within the terminal.
Check that the outer rubber sealing collar makes an effective
seal against the wall face.
