Heatmaster A450 Installation Manual

Flue details
Fluing your Heatmaster Gas fireplace.
The Heatmaster double skin flue kit, into timber and plaster must have
clearance of 25mm from any combustible material. Be sure the inner flue
crimped end faces down while the outer flue crimped end faces up. The first
and last length of flue must have ventilation holes, these cool the flue down
by allowing air to travel in between the two skins. Be sure to pop rivet (or use
self-tapers) and silicon flue lengths together along with the cowl. The flue
must protrude above the roofline by no less than 600mm with nothing
obstructing within 3600mm. (See diagram 3B)
