Building a Fire
1. Place several pieces of crumpled newspaper on the grate, crisscross the newspaper
balls with a couple of handfuls of dry kindling wood 3/4” thickness or less, then several
small pieces of dry firewood. Be sure the smokepipe damper is open if one is installed.
2. Ignite the paper. It will take 5 to 10 minutes for the fire to establish itself. Once you have
some good red hot burning embers, add larger pieces of wood. All installations are dif-
ferent. You will quickly learn the best way to start your unit.
3. After 30- 40 minutes you can adjust the intake damper according to your needs.
4. To reload the furnace containing existing hot coals, rake the coals evenly, add a few
smaller pieces over the coals. then load up. Do not use an automatic stoker with this fur-
nace.
5. Never leave the ash clean-out door open to allow more air to the fire as this allows
extreme heat to enter the automatic draft control located on the loading door causing
damage to the solenoid and thermostat.
Temperature Adjustment
A solid fuel fire burns cleanest in an environment with an unlimited supply of oxy-
gen. Allowing a fire to burn this way, however, produces a short, very hot fire with most
of the released heat going up the flue and the extreme temperatures causing a safety
hazard and possibly damaging the furnace. On the other hand, a smothered fire pro-
duces an extremely long, smoldering burn which is inefficient and produces large quan-
tities of soot or creosote with the danger of a clogged flue or stack fire.
The Bryan Furnace controls these factors by means of a thermostatically con-
trolled intake damper mounted on the furnace door. As the fire gets hotter, the thermo-
stat automatically decreases the amount of air to the fire to keep it under control.
Conversely, as the fire cools off, the damper begins opening to allow the fire more air.
Temperature adjustments are made by turning the knob on the door clockwise for
a hotter fire, and counter clockwise for a cooler fire. Make small adjustments with refer-
ence to the arrow on the knob and the hotter decal. Wait 15 to 30 minutes between
adjustments to allow the fire to reach equilibrium at the new setting.
CAUTION
Never use chemicals or fluids to start or
freshen-up a fire. Do not burn garbage,
gasoline, naphtha, engine oil or any
other fuel not approved with this unit.
CAUTION
The handle on the ash door can become extremely
hot, use care when handling. The ash door must be
securely closed whenever the furnace is unattend-
ed to prevent dangerous overheating.
