Furnace Operation
WALL THERMOSTAT OPERATION
Set the thermostat to the temperature desired. When the
furnace is warming up a cold room, there will be an initial
temperature overrun, then the temperature will stabilize.
REFUELLING
1. Have wood on hand to load the firebox.
2. Open the bypass damper for 30 seconds
3. Open the door slowly. Allow the chimney to draw off
smoke.
4. Load as much wood as you need (right up to the top in
cold weather).
5. Close the door and push in the bypass damper.
NOTE: Do not over- fire the furnace by leaving the door
open. The door should be open only when you light and
check the fire. Operation with the door ajar voids the
warranty.
OPERATION IF THE POWER FAILS
(NOT FOR USE IN FURNACES WITH DOWN FLOW
DUCTING)
1. Open the panel opposite to the air inlet to the wood
section to allow for air circulation.
2. Open all floor registers.
3. Adjust the draft manually by pulling up the chain just
below the damper motor lever, and placing it into the small
Figure 2: Operation during a power failure
slot beside the chain guide (see Figure 2)
Do not expect as much heat in cold weather, because duct
work is not designed for heating without a blower. When
power is restored, the damper motor will automatically pull the
chain off the slot and resume normal operation.
NOTE: The chain guide must be "clipped" by installers if
the furnace is installed to heat areas below the furnace.
FURNACE MAINTENANCE
DAILY
For the first little while, check the chimney and pipe until
experience shows how often cleaning is necessary. About
once a week, run the furnace at maximum with the bypass open
for one to two hours to burn off any creosote in the chimney
and pipes. This should greatly reduce how often you will
need to clean the chimney with a brush.
AS NEEDED
Any creosote build-up in the chimney and pipe over 6 mm
(1/4") should be removed with a brush. Make sure that the
bypass is open before you begin cleaning the chimney.
ASH REMOVAL
Ashes should be removed once they reach a depth of 100
mm (4") maximum. Let the fire burn out. Protect the area in
front of the furnace with a non- combustible material. Shovel
the ashes into a metal container with a tight fitting lid. Other
waste should not be put in this container.
The closed container of ashes should be placed outside
on a non-combustible surface, or on the ground, well away
from any combustible materials. If the ashes are disposed of
by burial or otherwise locally dispersed, they should be
retained in the closed container until you are sure that all of
the cinders have thoroughly cooled.
