7. Slide the flue back until it engages in the
elbow bayonet connection, twist anti-
clockwise to lock.
8. Drill through pilot hole and lock flue in
position with the self tapping screw

9. Make good the wall around the flue, both
outside and inside.
For extension kits refer to pages 38 & 39. If a
Horizontal Extension is required this MUST be
combined with a Standard Flue as shown below
in the Maximum Flue Length Guide.
If a in-line bend is required in the flue the
following rules apply:
A 90° in-line bend is the equivalent to a 1m
length of flue.
A 135° in-line bend is the equivalent to a ½m
length of flue.
The maximum equivalent flue resistance
allowed when using bends is:
30-80 models - 3.4m, 100 model - not allowed.
Note: For flue lengths less than the minimum
telescopic length, the tubes can be cut to suit.
Ensure that the same length is removed from
the inner and outer tubes to maintain a 20 mm
overlap (minimum).
For further information see the publications
supplied with the flue system.
