An additional safety system is built into your Bryan Furnace to control an
overtemperature condition. This system consists of a solenoid mounted in a separate
compartment above the damper box on the door. If electrical power to the furnace is
interrupted, the solenoid will automatically close the damper. Also, if air temperature in
the furnace reaches approximately 220° F, the solenoid will shut the damper and it will
not re-open until the furnace has cooled to approximately 160° F.
Do not use the
overtemperature safety system to control the fire with a maximum damper setting.
This causes an extremely inefficient burn with the fire smothered about half of the
time. Maximum heat output is achieved by setting the damper so that tempera-
tures do not quite reach an overtemperature condition.
NOTE: The solenoid will produce a low buzzing sound and the cover will be warm as long
as it is receiving electrical power. The noise will cease if the solenoid is closing the
damper due to either a power failure or over-temperature. If the solenod produces a loud
chatter, unplug the furnace immediately and see the trouble shooting guide.
CAUTION
The damper control mechanism
must not be altered for any reason.
CAUTION
Never operate your furnace so that any
portion becomes red hot. This is dangerous
as well as damaging to the furnace.
Creosote and Soot Formation and the Need for Removal
When wood is burned slowly, it produces tar and other organic vapors, which com-
bine with expelled moisture to form creosote (soot with coal burning). The creosote
vapors condense in the relatively cool chimney flue of a slow-burning fire. As a result,
creosote residue accumulates on the flue lining. When ignited, this creosote makes an
extremely hot fire.
The chimney connector and chimney should be inspected at least twice monthly
during the heating season to determine if a creosote build-up has occurred.
If creosote has accumulated, it should be removed to reduce the risk of a chim-
ney fire. If you clean your own chimney and stove pipe, we recommend purchasing the
equipment professionals use. Wire brushes are available in enough sizes and shapes to
be a snug fit inside any common flue.
NOTE:
Establish a routine for the storage of fuel, care of the unit and firing techniques.
Check daily for creosote build-up until experience shows how often cleaning is neces-
sary. Be aware that the hotter the fire, the less creosote is deposited and weekly clean-
ings may be necessary in mild weather even though monthly cleanings may be enough
in the coldest months. Have a clearly understood plan to handle a chimney fire.
