NOTE: Do not burn coke, charcoal, highly volatile Bituminous coal, sub Bituminous, lignite or cannel coal (sometimes called channel

coal or candle coal). Never burn wax or chemically processed logs, such as re logs as their use is for replaces only. Please follow all

guidelines in this manual concerning wood and coal burning applications due to safety concerns and to maintain warranty coverage.

BURN WOOD AND COAL ONLY!

Disposal of Ashes:

Heat resistant gloves are recommended. In order to remove ashes from your Shelter Furnace, open the ash door and slide the ash

pan to the rear of the furnace. Remove the ash pan from the furnace and dump the ashes into a metal container with a tight tting lid.

The closed container of ashes should be placed on a non-combustible oor or on the ground, well away from all combustible materials,

pending nal disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed

metal container until all cinders have thoroughly cooled.

The ash pan must be removed from your Shelter Furnace during operation. This precautionary measure is recommended because if the

ash pan is allowed to remain inside the furnace during operation, it will become dangerously hot to touch, block the ow of air under the

grates and reduce the efciency 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 ow of cooling air beneath the grates. This

ow 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 rebox will be starved of combustion air, greatly reducing the efciency and heat output of your Shelter Furnace.

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

Draft Blower:

The front 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 rebox producing a hotter re, 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 rebox, then the re dies, preventing the furnace from possible overheating

and damage. The manual combustion air spin damper control on the ash door should be set with a 1/8 inch gap. To begin, adjust slowly

by making 1 rotation at a time to nd the correct air setting.

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 ue of a slow burning re. As a result, creosote residue accumulates on the

ue lining. When ignited, this creosote makes an extremely dangerous re 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 re.

Creosote Prevention:

To help prevent the formation of creosote within the ue, ALWAYS BURN DRY, SEASONED WOOD. Dry wood burns hotter, allowing ue

gases to maintain temperatures above 212°F which should prevent the formation of creosote in the chimney. If the ue gas temperature

falls below 212°F, condensation occurs causing creosote formation and accumulation within the chimney.
