PREPARE FLUE UNIT (Figure 7)
6.1
Measure the total wall thickness from the
outside surface to the inside face. Add 80mm to this
measurement to obtain the correct length of flue unit
required.
6.2
Mark off the flue length on the outer (air)
tube measuring from the end of the terminal.
6.3
Insert the polystyrene ring between the inner
and outer tubes to support them and cut both tubes
squarely at the marked distance.
6.4
Important: Remove all polystyrene from the
flue unit after cutting.
6.5
Fit the flue unit tubes firmly over the spigots
at the rear of the fire. Make sure that the seam on the
flue tube is not at the bottom. Push on until the outer
tube touches the screw heads on the outer spigot.
6.6
If it is felt of benefit, the flue unit may be
additionally secured to the fire with one or two
suitable self tapping screws (we suggest No.6) before
installing into the wall as follows:-
6.6.1
Using a suitable metal cutting drill bit,
drill through the outer flue tube and outer spigot at
a distance of between 6mm & 7mm from the cut
end of the outer flue tube - See figure 8.
6.6.2
Fit the self tapping screw(s) in the drilled
hole(s).
6.7
Seal the flue unit all round the
circumference of the fire spigot with the tape
supplied.
6.8
Insert the plugs into the wall fixing holes.
Insert the top right fixing screw leaving the plain
shank proud to allow the top fixing keyhole in the
fire back to go over the screw.
6.9
Offer the fire complete with flue unit
through the wall and hook the top right keyhole
slot over the previously fitted wall screw.
6.10
Insert the top left and two bottom fixing
screws and tighten.
6.11
Seal, the outer flue tube to the outside
surface of the wall with fireclay or cement. Make
sure that the slots in the flue terminal are not
closer than 8mm to the wall and are not obstructed
by cement.
