9 Flue Preparation Telescopic and Standard Flue
9.2 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 9.3. 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 9.4. 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.
Top Side flue - Standard - with the flue elbow temporarily fitted,
measure the distance from the outside wall to the butt joint, see
diagram 9.5. If the measurement 'Y' exceeds 652mm, then the
appropriate length of extension pipe is required. The minimum
dimension for Lhd is 270 and Rhd 242 to suit a minimum wall
thickness of 75mm.
