must NOT be fitted where a precast flue or a flue
liner is used. For all other installations the restrictor
should be fitted. There may however, be certain
exceptional circumstances where fitting the restrictor
causes the fire to fail the spillage test. In such cases
the restrictor will have to be removed. After removal
conduct the spillage check again.
The restrictor is packed loose with the appliance and
is fixed with three screws. See figure 17.

1.
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.
2.
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.
3.
Mark the fireplace front surround through the four
fixing holes in the side flanges of the convection box. See
figure 18.
4.
Remove the convection box. Drill four holes in the fireplace front surround at the
marked positions using a no.12 masonry drill.
5.
Insert a rawlplug into each hole.
6.
Place the convection box back in position in the fireplace.
7.
Fit a woodscrew through each hole in the convection box flanges and tighten to seal the
box to the fireplace surround.
