hotbox must be kept away from the area which will be taken by the hotbox when it is

8. PREPARING APPLIANCE FOR INSTALLATION

IMPORTANT
Before continuing with the installation of this gas fire the aeration setting on
the burner must be checked. The aeration is factory set, but will require
adjustment (See section 16.1).
1. Detach the burner unit from the hotbox by removing two screws (See figure 10). Lift
the burner unit clear.
2. Fit the two "U" section seals to the bottom edges of the hotbox side flanges (See
figure 11).
3. It is important that the grommet
supplied in the loose parts pack is
fitted to the hole in the rear of the
hotbox.
For concealed connection only:
4. Pierce the grommet to allow the
pipe to pass through it. The grommet
should envelop the pipe. If the hole is
larger than the pipe, seal it with tape.
Do not pierce the grommet unless
the supply pipe is to pass through it.
5. The appliance is supplied with two fireback spacers. Do
not fit the fireback spacers if the fire is to be installed
into a precast or clay flue block system as in section
3.2.3. These should extend backwards to ensure sufficient
clearance from the back of the fireplace. Remove the label
and retaining screws from the rear sides of the hotbox.
Position the fireback spacer as shown in figure 12. Secure
the fireback spacers using the screws removed previously
and the two supplied with the fire.
6.This appliance is supplied with a flue restrictor for use
where the flue draught is excessive. The restrictor must
NOT be fitted where a precast flue or a flue liner is used.
For all other installations the restrictor should be fitted.
