OPERATING THE BIS ULTRA
3.2.1 Fuel
The BIS ULTRA is designed to work best when fuelled with seasoned cordwood.
Hardwoods are preferred to softwoods since the energy content of wood is relative to its
density. Hardwoods will result in a longer burning fire and less frequent refuelling. A
moisture content of 15% to 20% (seasoned) is recommended. Excessively wet wood will
be difficult to burn and will result in lower efficiency, increased creosoting and deposits
on the glass and in the chimney. Excessively dry wood will burn well but will also have
higher emissions and shorter burning time.
Do not burn scrap or garbage, treated wood or wood such as driftwood from the ocean
which has been exposed to salt or other chemicals. Salt or chemicals can corrode the
firebox and chimney. Do not burn large amounts of paper, cardboard, Christmas tree
branches or building construction materials. Intense firing with these materials may
overheat the fireplace, causing damage to the unit, a fire or even possibly igniting a
chimney fire if the chimney is creosoted
3.2.2 First Fires
Before using the fireplace make sure to remove the plastic wrapping on the doors.
Remove all remaining glue with mild soap. Ensure that the doors are well adjusted before
starting a fire (see page 11.)
The first 5 or 6 fires should be small fires of short duration (about 30 to 60 minutes).
This will help cure the refractory bricks. Ashes that will accumulate in the ashtray will
protect it from intense heat. The first fires may produce slight smoking due to drying of
the paint and steel and any dust accumulated on the fireplace will burn off at this time. It
may set off a smoke alarm located in the same room. For this reason the room should be
well ventilated for the first few fires.
3.2.3 Combustion Control
There is no flue damper in the BIS ULTRA. As is
common with airtight stoves, the combustion air damper
controls the air entering the firebox. This allows for a
more precise control of the fire. The combustion air
damper knob is located below the left door. It is opened
when moved completely to the left. This control should
be in the closed position when the fireplace is not in use.
This will minimise air leakage up the chimney.
The
combustion air control should be opened before
opening the door to minimise the possibility of back
draft coming into the room.
