not pierce the seal unless the supply pipe is to pass
through it.

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 thepierced hole in the rear seal.
7.1.2

CONVECTION BOX INSTALLATION
6.5
The appliance is supplied fitted with a flue restrictor
(see figure 8). If the appliance is being installed to a
precast flue or with a 125mm liner, remove the
restrictor since only in very exceptional circumstances
will there be sufficient flue pull on this type of flue
with the restrictor fitted. For all other installations
leave the restrictor in place.

7.1.5
Place the convection box back in position in the
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.

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 positions shown in figure 10 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.
