Heatmaster A series Installation Manual

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.
