CENTRAL HEAT SYSTEM
(option)
You have the option to heat remote rooms in your home with the heat generated by your fireplace. If this option is
installed, there will be a wall thermostat installed in the main room you want to heat, away from the room which
contains the fireplace. This thermostat controls the blower, which brings air to the other rooms in your home,
keeping them at the temperature you desire. When the blower is running, it takes air from the room the Onyx AP
is in, draws it around the fireplace and distributes it (See Options: Central Heating System FDHC6/FDHB6).
NOTE: The blower (FDHB6) can push warm air either up or down, and can also be zone controlled ( See Options:
Zone Heating).
HINT: If some evening you would like to enjoy the ambience of the wood flame, but you are a little too warm, turn
up the central heating thermostat and open a window by the thermostat. This will keep your room in front of the
fire from getting too warm.
OPERATION
LIGHTING
Slide the draft control under the doors all the way to the right. Light a fire in the fireplace, starting with paper and
kindling only. Then add 2-3" diameter pieces of wood. After the fire is established, close the doors to prevent over-
heating (see the Combustion Control section). Never use any flammable liquids. Once a coal bed is established,
add standard cord wood. Leave the draft control open until the fire is well lit, then adjust it to the level you desire.
WARNING:
Do not use a grate or elevate the fire.
THE FIRST FIRE
Before the first fire, be absolutely sure to wipe off all fingerprints and debris from the gold plating.
The
plating undergoes a sealing process during this first fire, and the acid from your finger prints will permanently etch
the gold plating. You will experience a slow start-up during the first fire. The refractory bricks still contain moisture
and take a good hot fire to get rid of the moisture. While there is moisture in the bricks, the bricks will be black with
smoke deposits. When the moisture is gone, the bricks will become white. You may also experience a slight odour
during the first few fires. This odour results from curing paint and the burn-off of residual oils.
REFUELLING
Fuel wood can be of any species, however, ensure that the wood is well seasoned and kept under cover. Sixteen
to eighteen inch lengths work the best.
NOTE: The central heat and internal blowers, if installed,
should be shut off during refuelling.
The door should be opened slowly, to keep smoke from
spilling into your room. If you do have smoke spillage,
check to see that all kitchen and bathroom fans have been
shut off. They can cause a vacuum in the house, which
pulls smoke out of the fireplace.
REFRACTORY BRICKS INSTALLATION
The refractories or refractory brick for the Onyx AP fireplace
are placed in the fireplace at the factory. If, for any reason they
should need to be replaced the following order should be
observed.
The two side refractories (11.1.N & 11.2.N) should be placed in
the firebox first. The two back refractories (11.3.N) should then
be placed in the firebox. The refractory with a hole in it (11.7.N)
