10.10 Flue Fitting
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.
Long lengths of ues must be secured to the walls or ceilings
they run against. Use at least one xing bracket for every ue
extension that is used.
After cutting inner ue tubes ensure that you de-burr and
chamfer the male tube end to prevent damage.
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.
Remove the ue elbow.
Separate the ue duct from the terminal by twisting to release
the terminal catch, then pull out of the retaining seal, refer to
diagram 10.17.
The ue duct cutting length (L + 11mm.) is shown in diagram
10.17.
The air duct should be cut at the opposite end to the terminal
The plastic ue duct MUST be cut at the opposite end to the
terminal catch.
The plastic ue duct extensions MUST be cut at the opposite
end to seal.
Insert the ue duct into the air duct terminal assembly,
remembering to engage the catch within the terminal.
Fit the sealing collar behind the locating lugs on the ue
terminal, see diagram 10.18.
Push the ue assembly into the wall, externally or internally,
initially 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 into the ue elbow.
Secure the ue elbow in position on top of the boiler with four
torque headed 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 the correct alignment of the terminal, 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 10.18.
Slide the internal trim ring back against the wall, securing in
place with a small amount of sealant if required.
NOTE: If the air and ue ducts have been correctly cut to the
instructions the sealing collar should t ush with the outside
wall.
