INSTALLER GUIDE

8.3 The flue restrictor.

This appliance is supplied with a flue restrictor for use where the flue draught is
excessive. Generally we recommend the restrictor is NOT fitted where a precast flue,
metal flue box or a flue liner is used,
however, certain flues may work
sufficiently to warrant its use. There
may however, be 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 two
No.8 X 3/8 screws provided

9. CONVECTION BOX INSTALLATION

9.1 Method 1- Front fixing to fireplace surround.

1. Make sure that the fireplace front surround area is sound enough to take the fibre
plugs and woodscrews. If necessary, make sound with 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 grommet.
3. Mark the fireplace front surround through the four fixing
holes in the side flanges of the convector box (See figure
13).
4. Remove the convector box. Drill four holes in the
fireplace front surround at the marked positions using a
suitably sized masonry drill for the fibre plugs supplied.
5. Insert a fibre plug 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.
