Larger voids around the box can be filled with a non combustible insulation.
Once in position fix the outer box by drilling through the fixing holes located in the base and screw/bolt to the base
of the opening using suitable fixings.
Where the opening is significantly higher than the outer firebox, the space may be filled by brickwork. Place a layer
of insulation beneath the bricks to provide an expansion joint on top of the outer firebox in front of the adaptor to
allow for expansion and contraction and to protect the wall above from excess heat. If more than three or four
courses of brick are needed, these should be supported on a lintel or steel bar between the jambs.
Where slate or marble slips are used, these should be placed behind the frame to form a sliding contact and thus
allow for the expansion of the fire. Do not allow slips, marble, plaster or brickwork etc to abut the edge of the frame
or to have direct contact with the firebox as expansion of the fire may cause them to crack. Use a strip of insulation
as an expansion joint where necessary.
Note: - If an external primary air supply is to be used then the knockout in the rear of the outer box must be first
removed before fitting the outer box into the opening. Then, depending on the route of the flexible pipe a hole or
clearance needs to be made behind the outer box to accommodate the pipe routeing it to external air.
External Air Supply Fitting
The primary air can be taken from the room or alternatively it can come from an external source from outside the
building.
If taken from the room then air ducts are required to the room, as the fire will take its primary air from the chamber
around the fire that is fed by air from the room. See section on Air supply for details.
If air is required to be brought in from an external source then first the knockout at the rear of the outer box should
be removed by careful removal with a hammer.
This will allow a 63mm flexible pipe to be pushed through the back of the outer box and over the air chamber pipe
attached to the inner firebox.
The flexible pipe should be held in place with the circular clamp supplied.
It is usually easier to fit the flexible pipe to the inner firebox first then slide the flexible pipe through the knockout
hole in the outer box as the inner box is being slid into place. Then at this point the flex can be fed through any
holes in the wall or floor to an external air source. An open grille maybe attached to the end of the flexible pipe to
stop debris from blocking the pipe. Ensure that the grille does not restrict the air supply.
