2.2 Install the Flue
Maximum flue lengths are as follows:
100 Model - 680mm
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 20mm
overlap (minimum).
These instructions are for rear and side flue
applications.
Rear Flue
1. Measure the wall thickness and add 66mm
(or 106mm for installations using the System
Boiler or Stand Off Kits).
Side Flue
1. Determine the X dimension (wall thi
distance to boiler centreline).
For both Rear & Side Flues
2. Extend the telescopic flue to the required
length, minimum 20mm overlap.
3. Drill through the pilot hole and secure with
self tapping screw.
4. Wrap tape around the joint on the outer duct
to seal the flue, slide drip ring into a position
to coincide with the air gap in the wall (cavity
wall) .
5. Slide the flue through the hole until it stops
on the pin.
6. The boiler is supplied with the flue elbow set
to the rear. For side outlet slacken the
screws and turn the elbow to the required
position and re-tighten screws. Ensure that
the seals are still correctly located.
7. Hang the boiler onto the mounting bracket.
To square the boiler to the wall adjust the
boiler alignment screws on the back panel of
the boiler.
8. Slide the flue back until it engages in the
elbow bayonet connection, twist anti-
clockwise to lock.
