5.5 Fitting the Fan Box
1. Place the power supply cable and fan to fire harness in
their intended positions, passing through the hole in the wall
where applicable.
2. Either fit the liner into the recess and pass the fan to fire
harness through the hole in the liner, or complete the false
chimney breast or surround incorporating the liner as
appropriate.
3. Unpack the fan box assembly and undo the screws
retaining the brown fan box cover. Take the loose sponge
seal from the fan box (Fig. 21).
4. Taking note which is the top, undo the screws securing
the fan box to the fan box collar. Slide the collar into the wall
(Fig. 20), mark the fixing holes and remove. Below each
collar fixing hole also drill a 10mm diameter recess to accept
the threaded bushes in the collar.
5. Drill and plug the holes and refit the collar using suitable
screws. Any gaps around the edges should be sealed (Fig.
20).
6. Fit the larger diameter flue duct to the rear bayonet fixing
on the fan box ensuring it is located correctly and the seal is
made (Fig. 21). Depending upon the wall thickness it may be
necessary to cut the flue - see Section 5.6.
7. Fit the sponge seal to the 2 sides and top of the fan box
mounting face (Fig. 21).
8. Remove the sensing tube from the fan. Undo the screws
holding the pressure switch bracket to the fan box. Pull the
bracket and switch from the box (Fig. 21).
9. Undo the two screws securing the fan control unit bracket
to the fan box and draw the bracket forwards (Fig. 22).
10. Remove the grommet from the slot in the cut-out at the
top right of the fan box. Cut the grommet and lit it over the
power supply cable.
11. Connect the 3 pin plug to the socket on the fan control
unit bracket and re-fit the grommet into slot (Fig. 22).
12. Fit the fan control unit bracket to the fan box using the
two screws previously removed.
13. Connect the 8-pin plug from the fan box (Fig. 22) to the
8-pin socket on the harness. Connect the earth lead to the
screw on the rear face of the fan box.
