GENERAL OPERATION
Spindle
The spindle on the fire box 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 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 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
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 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.
Damper
The bypass damper is opened by pushing the handle towards
the rear and closed by pulling the handle towards the front. In
the open position, the flame path is diverted from the firebox
directly up the flue. In the closed position, the flames are
diverted down the sides of the heater, around the oven
before travelling up the rear of the heater and up the flue.
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 spindle before opening the door to eliminate the
chance of backdraft and smoke entering the room.
