Fitting the Blanking Plate
1. If the flue is not fitted in the fully forward
position, the rear blanking plate will need to
be cut to size, cut trim to length as required.
See Fig. 15.
• If fitting under a worktop then drill 2 pilot
holes through the holes in the rear blanking
plate plate and into the work top. Secure
the plate using 2 woodscrews (not
supplied).
2. Locate the top blanking plate as shown in
Fig. 15.
Balanced Flue:

as illustrated.
Note: Ensure that the correct allowance is
made for side outlet when the boiler is not
being pushed fully back.

Maximum flue lengths are as follows:
40 - 70 models 3.4 m
80 model 2.4 m
90 model 1.4 m
100 model 1.0 m
These are for rear or side flue applications
see Page 17 Fig. 16.

4. Extend telescopic flue to the required length,
minimum 20 mm overlap.
5. Drill through the pilot hole and secure with
a self tapping screw.

to seal the flue, slide drip ring into position to
coincide with the air gap in the wall cavity.
