GENERAL OPERATION
Spindle
The air spindle on the door controls the primary air to the
base of the fire. This controls the burn rate of the fire.
A tool for opening and closing the air spindle is supplied with
the heater. This can be used in instances when the spindle
control is too hot to touch. Alternatively, a glove or equivalent
can be used to adjust the air spindle.
Air Wash
A 2mm gap at the top of the door allows additional air to
enter the firebox, washing over the door glass keeping it clean
while also supplying necessary oxygen to the fire when the air
spindle has been fully closed.
If the draft is too high or low with the spindle completely shut,
the 2mm gap can be adjusted by loosening the two grub
screws in the top of the door (high-lighted in the image below)
with the Allen key supplied, adjusting the metal strip
accordingly and re-tightening the screws.
For example, an installation in a two-storey house with a tall
flue could have a very high draft. To reduce the draft, the gap
on top of the door could be reduced to 1mm.
Warning: Do not close this air gap completely as it will restrict
the draft too much. If the draft is too restricted, the fire will
produce a lot of smoke and cause the glass to blacken.
Door Handle
Warning: The door handle may get hot if the appliance has
been left in the high burn setting for an extended period. Use
a protective glove to open.
Open the air spindle before opening the door to eliminate the
chance of backdraft and smoke entering the room.
