CONVECTION BOX INSTALLATION

7.1 METHOD (1) - FRONT FIXING TO FIREPLACE
SURROUND
Make sure that the fireplace front surround area is sound enough to take the
rawlplugs and woodscrews. If necessary, make sound with a suitable cement.
7.1.1 Place the convection box centrally in the fireplace in the position in
which it is to be permanently installed.
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 seal.
7.1.2 Mark the fireplace front surround through the four fixing holes in the
side flanges of the convection box (see figure 13).
7.1.3 Remove the convection box. Drill four holes in the fireplace front
surround at the marked positions using a no.12 masonry drill.
7.1.4 Insert a rawlplug into each hole.
7.1.5 Place the convection box back in position in the
Fig. 13 Front fixing
fireplace.
7.1.6 Fit a woodscrew through each hole in the convection
box flanges and tighten to seal the box to the fireplace
surround.
7.2 METHOD 2 - CABLE RETENTION AND
FLOOR FIXING
Make sure that the areas at the back and towards the centre of
the fireplace floor are sound enough to take the eyebolts and
screws. If these areas have deteriorated due to prolonged use,
they should be made sound with a suitable cement.
7.2.1 Drill four holes in the rear wall of the fireplace for the
eyebolt plugs. The holes should be drilled within the range of
Fig. 14 Eyebolt positions
positions shown in figure 14 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.
7 2.2 Insert a fibre plug into each hole. Use the rawlplugs 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.
7.2.3 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 seal.
7.2.4 The convection box has two holes at each side of the convected air
Fig. 15 Upper cable retaining
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 15). Give the cables a pull so that they grip against the
convection box flanges.
7.2.5 Thread the cables through the upper eyebolts in the rear wall and
then through the lower eyebolts. Return the cables through the holes near
the bottom of the convection box back panel and through the "V" shaped
brackets near the bottom front sides of the convection box (see figure 16).
7.2.6 Place the convection box fully back into the fireplace opening so that
it is sealed against the fireplace front surround.
