Try to cut it as evenly as possible with minimum offset. File or otherwise finish your cut end to remove any offset
and swarf.
j)
Mounted on the heat exchanger is a round plastic baffle which secures the air intake filters. The extraction fan
adjacent to these filters goes to the outside wall. Use the PVC weld adhesive to stick the small tube you have cut to
length onto the end flange of the extract fan and allow the adhesive to set. Protect the front cover at all times from
dirt and scratches.
k)
Now fit the wall plate to the wall. The wall plate is marked top on the front face. If the sleeve on the rear wallplate
does not fit into the drilled hole, carefully open up the hole in the plasterwork until the wall plate will fit flush
against the wall and is central in the drilled hole. (Use the remnant piece of large diameter tube as a template to
ensure it is central). Mark out and drill the screw holes and chisel out a groove for the wiring from the cable entry
hole (top left) upwards to the ceiling (or in the direction you have determined for the transformer or remote
control). Fit screw plugs into the screw holes.
l)
Fit the wall plate onto the open end of the large tube fitted with the outside cowl. Measure the distance from the
back edge of the wall plate to the other end of the tube. The tube should not extend beyond the outside wall
finisher.
Use the PVC weld adhesive to stick the wall plate to the outside tube. Ensure that the outside cowl is the right way
up (louvres pointing downwards to avoid rain ingress and the louvres are level to the wall plate). Push the outside
cowl/tube/wall plate assembly into the hole in the wall. Make sure that ’top‘ is correctly positioned and pull the
two core cable through the cable hole, check that there is a small downwards gradient in the tube
(see section f). Screw the wall plate to the wall ensuring that it is level with the ceiling. It is important to do this now
in order to accommodate the angle of the tube in the back of the wall plate before the glue sets.
