10 Telescopic Flue - Length, Preparation and Installation

IMPORTANT:-
The ue 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 ue system, ensure that debris
such as mortar, lings or swarf are cleared from the ue
system before completion.
Inspect the ue pipes before tting and do not install damaged
or dented ue components.
When assembling the ue system, ensure that the inner
seals are not damaged, do not install a ue component with a
damaged seal.
When tting ue elbows ensure that they are tted at the
correct angle to avoid strain, this will ensure that the seal ts
correctly preventing leakage.
With the air duct seams aligned and the ue 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 ue duct. Secure with screw provided and
tape the joint, see diagram 10.8.
Fit the sealing collar onto the locating ring on the ue terminal,
see diagram 10.9.
With the ue elbow removed, push the ue 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 ue assembly to be drawn back up to the ue
elbow.
Secure the ue elbow in position on top of the boiler with the
four screws supplied.
Draw the ue assembly from wall and engage the ue duct
into the elbow and butt t between the air duct and ue elbow.
Fit the securing collar into position.
Ensuring correct alignment of the ue, 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 ue duct.
Fit the securing collar and secure with screws provided, see
diagram 10.10.
Slide the internal trim ring back against the wall, securing in
place with a small amount of sealant if required.
Insert the ue 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.
