be drilled within the range of positions shown in figure 17 using a suitably sized
masonry drill for the wall plugs supplied. 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 convection box 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 convection box. If
a concealed connection is being used, insert the
convection box into the fireplace feeding the supply
pipe through the pierced hole in the rear grommet.
5. The convection box has two holes at each side of
the convected air opening. Insert one end of each
cable (one cable each side) from the back through the
lower of the two holes and return the end through the
upper of the holes (See figure 18). Give the cables a
pull so that they grip against the convection box flanges.
6. Thread the cables through the eyebolts. Return the
cables through the holes near the bottom of the
convection box back panel (See figure19) (For precast
or clay block flue systems return the cables through
the slotted holes in the side of the convection box).
7. Place the convection box fully back into the fireplace
opening so that it is sealed against the fireplace front
surround.
8. Drill a hole into the fireplace floor through each of the
two holes in the base of the convection box using a
suitably sized masonry drill for the wall plugs
supplied (See figure 20).
9. 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.
Fit a woodscrew in each plug and tighten.
Always screw the base into position before
applying tension to the cables. This will ensure a
tight seal between the top of the convection box
and wall.
