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 four
torque headed 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.
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.
