because if the ash pan is allowed to remain inside the furnace during operation, it will become dangerously hot to touch, block

the flow of air under the grates and reduce the efficiency of the furnace.
Remove the ashes from your Shelter Furnace at least once a day, or as often as necessary to ensure the ashes do not

accumulate to the height of the grates. If ash build-up occurs at grate level, it will cause premature failure of the grate system, voiding

the warranty on the grates. Unacceptably high temperatures will result because the ashes have restricted the flow of cooling air beneath

the grates. This flow of air was designed to not only cool the grates, but to also provide warmed air for better combustion. If the ash

level is improperly maintained the firebox will be starved of combustion air, greatly reducing the efficiency and heat output of

your Shelter Furnace.
CAUTION: HOT SURFACES. KEEP CHILDREN AWAY. DO NOT TOUCH DURING OPERATION.

Draft Blower:

The draft blower plays an important role in the operation of your Shelter Furnace. When the wall thermostat calls for heat, the draft motor

turns on and supplies fresh air into the firebox producing a hotter fire, which in turns provides more heat in the heat chamber. The heat

is then sent through the duct system throughout your home. When the wall thermostat temperature is met, the draft blower shuts off until

the thermostat calls for heat, beginning the cycle again. The draft blower has a slide cover located on the side of the motor that is factory

preset, with an opening of approximately 3/8”. The cover should be fully closed only when there is a power failure and electricity is

lost. With the cover closed, no air is introduced into the firebox, then the fire dies, preventing the furnace from possible overheating and

damage.

Creosote Formation and Need for Removal:

When wood is burned slowly, it produces compounds in exhaust smoke which combine with expelled moisture to form

creosote. The creosote vapors condense in the relatively cooled chimney flue of a slow burning fire. As a result, creosote

residue accumulates on the flue lining. When ignited, this creosote makes an extremely dangerous fire in the chimney. The chimney

connector and the 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 risk of a chimney fire.

Creosote Prevention:

To help reduce the formation of creosote within the flue, ALWAYS BURN DRY, SEASONED WOOD. Dry wood burns hotter,

allowing flue gases to maintain temperatures above 212°F which should reduce the quantity of creosote in the chimney. If the

flue gas temperature falls below 212°F, condensation occurs causing creosote formation and accumulation within the chimney.
As an added precaution, periodic chimney inspections are recommended during the heating season to determine if creosote formation

has occurred. For safety and efficiency, it is recommended that the chimney system be inspected and cleaned prior to each heating

season.

Chimney Fire Warning:

In the event of a chimney fire, take the following actions immediately:

• Activate and toss a Chimfex™ Dry Chemical Chimney Fire Extinguisher into the firebox.

• Close the ash door, fuel door and slide cover on the draft motor.

• Alert entire household and prepare to evacuate if necessary.

• Call your local fire department.

Power Failure:

In case of power failure, to prevent your Shelter Furnace from over-heating and causing damage to the electrical components, do NOT

add more fuel to the firebox.

There is no warranty on electrical components damaged due to power failure.
