Firebox Installation - Baxi 746 Installer's Manual

9.1 Firebox installation.

1. Make sure that the relevant
areas at the fireplace back are
sound enough to take the
eyebolts. If these areas have
deteriorated due to prolonged
use they should be made
sound with a suitable cement.
2. Drill four holes in the rear
wall of the fireplace for the
eyebolt plugs. The holes
should be drilled within the
range of positions shown in
figure 13 using a no.12
masonry drill. The holes
should be equidistant each side of the centre line of the
fireplace to ensure that the appliance finishes centrally
in the opening when tension is applied to the cables.
3. Insert a fibre plug into each hole. Use the fibre plugs
supplied with this appliance - Never use plastic plugs
instead of the fibre plugs supplied. Screw the eyebolts
into the plugs. Make sure that the bolts are secure.
4. Place the hotbox unit close to the fireplace but allow
sufficient access into the fireplace opening so that the
cables can be threaded through the eyebolts and
returned through the back of the hotbox. If a concealed
connection is being used, insert the hotbox into the
fireplace feeding the supply pipe through the pierced hole
in the rear grommet.
5. The rear of the hotbox has a slot and hole each side of
the outlet opening. Assemble one end of the cable to the
top of the fire by passing it through the small round hole
and locking by positioning the cable in the adjacent slot
(See figure 14). Give the cables a pull so that they grip.
6. Thread the cables through the eyebolts. Return the
cables through the holes near the bottom of the hotbox
side panels (See figure 15).
7. Place the hotbox fully back into the fireplace opening
