9.13 Flue Length
Remove the top fl ue outlet cover secured with four screws, see
diagram 9.2.
Temporarily fi t the fl ue elbow, measure the distance from the
outside wall to fl ue elbow. If the measurement ‘Y’ exceeds
652mm, then the appropriate length of extension pipe is re-
quired.
9.14 Flue Fitting
Remove the fl ue elbow.
Separate the fl ue duct from the terminal by twisting to release
the terminal catch, then pull out of the retaining seal, refer to
diagram 9.9.
The fl ue duct cutting length (L + 11mm.) is shown in diagram
9.9.
The air duct should be cut at the opposite end to the terminal
The plastic fl ue duct MUST be cut at the opposite end to the
terminal catch.
The plastic fl ue duct extensions MUST be cut at the opposite
end to seal.
The cut ducts must be de-burred and all fi lings and debris re-
moved.
Insert the fl ue duct into the air duct terminal assembly, remem-
bering to engage the catch within the terminal.
NOTE: If you require to lubricate the seals to ease installation,
do not use mineral oils or grease, silicon grease or water is
recommended.
Fit the sealing collar behind the locating lugs on the fl ue termi-
nal, see diagram 9.6.
Push the fl ue assembly into the wall, externally or internally, ini-
tially 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 fl ue assembly to be
drawn back into the fl ue elbow.
Secure the fl ue elbow in position on top of the boiler with four
torque headed screws supplied.
Draw the fl ue assembly from wall and engage the fl ue duct into
the elbow and butt fi t between the air duct and fl ue elbow.
Ensuring the correct alignment of the terminal.
Fit the securing collar into position, 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 fl ue duct. Fit the
securing collar and secure with screws provided, see diagram
9.13.
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 fl ue ducts have been correctly cut to the
instructions the sealing collar should fi t fl ush with the outside
