6. Remove the fan unit cover (4 screws) and place to one side.
7. Using the template as a guide, drill the outer wall for fixing the fan unit and insert the
plastic plugs provided.
8. From outside feed the 3 cables from the fan unit through the opening in the wall, then
feed the mains and switch cables through the 20mm plastic conduit in the inner wall.
9. Secure the fan unit to the wall using the screws provided into the plastic plugs.
10. CARRY OUT ELECTRICAL INSTALLATION STEPS 1-5
11. Install the fire surround or false chimneybreast if not already fitted.
12. Position the wall box on the non-combustible base and feed the gas supply pipe
through the left hand rear grommet hole. The burner supply cable with 4-way plug
should be passed through the right hand grommet hole. Bring through only sufficient
to reach the burner, coiling up any surplus behind the insulating slab.
13. Secure the wall box in its final position using the screws provided.
14. Wrap the length of galvanised wire provided round the connecting duct, twisting the
ends to secure. Position the wire so that it will be sited centrally in the cavity space,
with the twist underneath to form a drip collar (see Figs. 3,4,5 & 6).
15. Slide the connecting duct through the back of the wall box into the spigot on the fan
unit fitted to the outside wall. Take care not to damage the seal in this spigot. If the
duct is difficult to engage, coat the seal with liquid soap. Secure inside the wall box
with the screws provided, ensuring that the gasket is positioned correctly.
16. COMPLETE ELECTRICAL INSTALLATION STEPS 6 and 7.
17.
Remove the protective cover from the fan motor.
18. Fit the fan unit cover with the four screws provided.
19. If the wall box is not fixed through its base, then secure the assembly to the surround
using 4 screws into the previously inserted plastic plugs.
20. Slide the convection box into the wall box, feeding the gas pipe and cables through
the appropriate grommets.
21. Secure the convection box through the back to the wall box with the screws provided.
Electrical installation
NOTE: THIS APPLIANCE MUST BE EARTHED; Electrical wiring work must conform to current I.E.E.
Wiring Regulations.
All cables should be routed as shown in Figs 10a or 14.
1.
Place the insulation slab in front of the cables
and fix to the wall with masonry
nails and washers supplied, taking care not to damage the cables. See Figs. 10a, 14,
and 8.
2. The mains cable should be trimmed to length and connected to a switched fused spur
(3A fuse) with at least 3mm contact separation in all poles.
3. Decide with the user on a suitable location for the switch plate and fit the galvanised
back box.
4. Route the 7-core cable as required, trim to length and connect to the rear of the switch
plate taking care to connect the cores as indicated on the label.
5. The 4-way plug and cable passes through the right hand hole in the side of the
convection box for connection to the burner (see Fig. 10a). (Do not bring the earth
cable through this hole). After measuring the length required, coil up any excess and
place between the insulation slab and the wall.
6. Connect the earth cable to the earth bolt in the convection box side, ensuring that the
serrated washers are fitted as shown in Fig. 10b.
7. See Fig. 19, page 17 for a complete wiring diagram.
