BUILDING A FIRE:
1. Place the “Manual/Off/Automatic” switch in the “Automatic” (bottom) position for thermostat control
operation. Turn rheostat knob clockwise (it will click from “Off” position to “On”) so you can vary the speed
of motor.
2. Open the door.
3. While looking inside firebox, operate the damper bypass plate in and out observing the movement. This
should operate freely and close completely. Open the damper bypass.
4. Open the air controls on each side of stove (pull out).
5. Twist 4 or 5 pieces of non-colored newspaper in a roll and place on the floor of the firebox.
6. The Model 91 Bay is not designed for use with grates, andirons or other methods of supporting the fuel.
7. Lay several pieces of dry kindling on top of the newspaper.
8. Place three or four small pieces of firewood, 2-3" in diameter, on top of the kindling.
9. Light the newspaper, close and latch the door. Don’t leave the fire unattended at this point. The draft should
start quickly. If not, it may be necessary to preheat the chimney to get the draft started. To do this, open the
door and add newspaper to the top rear of the wood. Light or let this paper ignite and allow to burn while
holding the door slightly open. Do not leave the stove unattended with the door open! Once the draft has
started, close and lock the door. A direct connect (option) usually solves this problem. Check with your
dealer.
10. After embers and a coal bed have been established, load the heater with wood. DO NOT BUILD A LARGE
ROARING FIRE! Initially, build 2-3 small fires in order to cure the paint on your stove.
11. Within the 20 minute time frame, you can begin to add your wood. Remember—DO NOT FILL firebox
during your first 2 to 3 fires!
12. Once your fire is burning well, close the bypass damper completely (push in). Gradually close the primary air
controls (push in). You will have to experiment with the primary air controls to accommodate your draft. If
you close them too soon, your fire may die down too quickly and go out. Close them gradually, a little at a
time, until you can close completely.
BURN RATES
A. Low Burn Rate: Set primary air controls (both) almost closed - leave open about 1/8". Set the rheostat
for fan control between the low to medium speed. This burn rate is the most desired and most efficient,
but can only be achieved after a fire has been established and burning on its own controlled air. Close
the bypass damper (push in).
B. Medium-Low Burn Rate: Partially close primary air controls (push halfway in). Close the bypass
damper (push in). Set the rheostat for the fan control halfway between low and high.
C. Medium-High Burn Rate: Set the primary air controls almost fully open. Close the bypass damper.
Set the rheostat for the fan control between the medium position and the high position.
D. High Burn Rate: Set primary air controls wide open. Have the damper closed. Set the rheostat for the
fan control all the way on high. USE CAUTION! Close shotgun air control after 5 minutes.
E. Wood Loading: During refueling, open (pull out) the bypass damper to allow smoke in the firebox to
escape - wait a few seconds, slowly add wood. Immediately close door and bypass damper. Open
primary air control wide open for 2 minutes to charge the wood. After most of the wood has burned and
if you are not planning on reloading immediately, it may be necessary to open damper bypass, then the
door, and rake the wood and coals into a pile near the front center of the firebox. (Be certain wood
chunks are pulled out of the rear corners.) Close the door and the damper bypass. This step will assure
continued combustion and thorough burning of the wood.
You will have to experiment with the fire rate until you find the particular setting for heating your home.
Chimney drafts, tightness of the house, doors, windows, insulation in the house, and atmospheric conditions all
influence which setting you must have, so it may take several firings to learn the setting necessary for your
installation. Heating capacity is based on BTU output and the conditions listed above. These conditions will
affect the heating capability of your heater.
Although the catalytic stoves decrease ash residue, routine removal of excess ash is still necessary.
