BURN WOOD ONLY!
Fuel Recommendations:
For the SF4200 model, heat resistant gloves are recommended when loading the furnace. Only use dry, seasoned hardwoods in your
Shelter Furnace rather than high resin woods such as pine. Firewood should be cut at least one full season prior to the time of
its intended use for optimum heat output. Firewood should be stacked to provide a free flow of air between the logs; this allows
the wood to season faster. If wood is stored outdoors, it should be completely covered year round to protect it from moisture
and exposure to the elements. Use extreme caution when opening the ash drawer and fuel door during operation, temperatures can
exceed 300° F. Wait at least 10 seconds after releasing the first latch, then proceed to the fully open position. The dual latch system
has been incorporated as a safety feature, which was designed to reduce the possibility of gaseous ignition. Heat resistant gloves are
recommended when opening the fuel door or emptying the ash pan.
This wood heater needs periodic inspection and repair for proper operation. If you observe excessive smoke, check to be sure you are
burning properly seasoned cordwood and that there are no gaps in the gaskets on the door of the unit. When it becomes necessary to
replace the gaskets:
• Order part number FCGSKT58 (fuel door) and/or FCGSKT12 (ash door)
• Remove old gasket
• Install new gasket in gasket channel of door
• Cut off excess gasket, ensure that there is no gap where the ends of the gasket material meet
DISPOSAL OF ASHES:
Heat resistant gloves are recommended. In order to remove ashes from your Shelter Furnace, 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 fitting lid. The closed container of
ashes should be placed on a non-combustible floor or on the ground, well away from all combustible materials, pending final 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. 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.
ALWAYS KEEP YOUR WOOD COVERED YEAR ROUND. DRY WOOD WILL PRODUCE A HIGHER BTU OUTPUT AND A LONGER
BURN TIME.
HEAT DUMP AND FUSE LINK SYSTEM:
The Shelter Furnace has a patented automatic safety feature, the Heat Dump Release System. In the case of a power failure, the heat
dump release will open the spring-loaded lid when the internal furnace temperature reaches 370° F. The heat sensitive fuse link, located
within the top of the heat chamber, causes the lid to open, allowing the excess heat to escape. This safety feature is designed to activate
before any extreme heat can damage the furnace.
In the case of a power failure, connect your Shelter Furnace to a generator immediately. If the heat dump release lid should open, do
not continue to burn the furnace. DO NOT UNPLUG THE FURNACE. Close the draft dampers and set the wall thermostat to the lowest
possible temperature. DO NOT add fuel, which will allow the fire to die. After the electricity is restored, replace the fuse link before
resuming normal operation.
