Final assembly
This section describes the installation of the burner unit
1. Connect the earth link lead from the burner to the earth bolt in the convection box side
as shown in Fig. 10b.
2. Secure the burner to the convection box using the two screws provided, through the
holes in the front of the legs.
3. Connect the gas supply pipe to the inlet elbow.
4. Remove the ignition unit cover beneath the burner (Fig. 14). Route the 4-core cable as
shown and plug into the printed circuit board. Fit the cable grommet into the hole in
the side of the convection box and replace the cover. Do not allow the cable to loop up
under the burner.
5. Install the ceramics and coals. The ceramic components are fragile and should be
handled with care. Refer to Figs. 11 and 12 for positioning of ceramic fibre blocks and
coals.
6. Place the ceramic matrix on the burner, pushing it back against the upturned edge of
the burner plate.
7. Spring forward the slotted front plate and slide the front ceramic down as far as the
stops.
8. Remove the coals from the bag; note that there are various sizes supplied with the
burner. Place them on the ceramic blocks in accordance with Fig. 12.
If a flat trim or box trim has been supplied, attach it to the fire flange by means of the magnets. If
the optional canopy trim has been supplied, first remove and discard the existing front cover by
undoing the two screws in its bottom edge, then secure the canopy trim using the same fixings.
