Flue details
Fluing your Heatmaster fireplace.
The Heatmaster double skin flue kit, into timber and plaster must have clear-
ance of 25mm from any combustible material. Be sure the inner stainless steel
flue crimped end faces down while the outer galvanized flue crimped end faces
up. The first length of galvanized flue must have ventilation holes at the bottom;
these cool the flue down by allowing air to travel in between the two skins.
Be sure to pop rivet (or use self-tapers) each stainless and galvanized flue
length together along with the cowl.
The flue must protrude above the roofline by no less then 600mm
with nothing obstructing within 3600mm.

Hearth details
Hearth details for combustible flooring.
The hearth required under the Heatmaster firebox consists of two sheets of
6mm thick fibre-cement with a 1mm thick sheet of steel between them. It
must be spaced off the floor with non-combustible spaces (square tubing)
to give a 25mm ventilated air gap (Fig 2A). It should extend 350mm
in front, 25mm behind and 200mm either side of the
firebox opening. (Fig 2B)
