See installation drawing
Position of Fire
The Through wall fire has glass on one side, the other side is open. It must be
confirmed which way the fire is to be installed. The fire can not be reversed after
installation. The open side has the higher heat output.
Hearth
The minimum hearth size is 300mm into the room and 150mm wider each side than
the fire. ( 300mm x 1200mm)
Hearth – Open side
A non combustible hearth must be provided in front of the open side of the Through
wall fire unless the floor is non combustible.
Hearth – Glass side
A non combustible hearth must be provided in front of the glass side of the Through
wall fire unless the floor is non combustible or the fire is raised a minimum of 300mm
above floor level.
Height of fire from floor
It is important to confirm the height the fire is to be installed above the floor level.
This is usually the hearth height. For example if the hearth is 100mm high then the
fire needs to be 100mm high. (
note-
some elevated installations specify the fire higher
than the hearth). Once the height is confirmed a platform needs to be built to support
the firebox. The platform can be of timber construction. It needs to be sturdy and
level.
Gas Supply
A suitable gas supply needs to be provided at the right hand side of the timber frame
cavity. This is as looking at the cavity from the side which will be the open side of the
fire.
See installation drawing
The pipe sizing should be calculated to supply gas to suit the megajoule rating of the
fire. See rating chart. The gas supply should be reduced down to 10mm copper pipe at
the fireplace location and left with a coil of approx 1 metre to feed into the firebox.
