8 Flue Preparation Telescopic and Standard Flue
8.3 Preparation
Telescopic:
The Telescopic Flue system MUST NOT be cut.
Adjust the flue to your required length "Y", ensure the air duct
seams line up 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 8.5.
Standard:
Separate the flue duct from the terminal by twisting to release
the terminal catch, then pull out of the retaining seal, refer to
diagram 8.6.
The duct cutting lengths are shown in diagram 8.6.
The air duct should be cut at the opposite end to the terminal
fixing.
The terminal plastic flue duct MUST be cut at the opposite end
to the catch.
The plastic flue duct extensions MUST be cut at the opposite
end to seal.
The cut ducts must be de-burred and all filings and debris
removed.
NOTE: If you require to lubricate the seals to ease installation,
please do not use a mineral oil based grease, we would
recommend the use of water.

8.2 Flue Length
Top Rear flue - Standard - with the flue elbow temporarily
fitted, measure the distance from the outside wall to the butt
joint, see diagram 8.3. If the measurement 'Y' exceeds 652mm,
then the appropriate length of extension pipe is required. The
minimum dimension is 187mm to suit a 75mm min wall thickness.
Top Rear flue - Telescopic - with the flue elbow temporarily
fitted, measure the distance from the outside wall to the butt
joint, see diagram 8.3. If the measurement 'Y' exceeds 525mm,
then the appropriate length of extension pipe is required, if the
dimension is less than 320mm DO NOT cut the flue, it can
project to a maximum of 600mm, if this is not desirable then a
Standard flue MUST be used and cut to length.
Top Side flue - Standard - with the flue elbow temporarily fitted,
measure the distance from the outside wall to the butt joint, see
diagram 8.4. If the measurement 'Y' exceeds 652mm, then the
appropriate length of extension pipe is required. The minimum
dimension for Lhd is 270 and Rhd 167 to suit a minimum wall
thickness of 75mm.
Top Side flue - Telescopic - with the flue elbow temporarily
fitted, measure the distance from the outside wall to the butt
joint, see diagram 8.4. If the measurement 'Y' exceeds 525mm,
then the appropriate length of extension pipe is required, if the
dimension is less than 320mm DO NOT cut the flue, it can
project to a maximum of 600mm, if this is not desirable then a
Standard flue MUST be used and cut to length.
