the fuel door, regulating the spin draft or emptying the ash pan.
DISPOSAL OF ASHES:
Heat resistant gloves are recommended. In order to remove ashes from your Shelter Furnace, slide the ash drawer to the rear of the
furnace. Remove the ash drawer 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 (either wood or coal), which will allow the fire to die. Pull out by pass rod. After the electricity is
restored, replace the fuse link before resuming normal operation.
Caution: If your heat dump opens without a power failure here is a list of possible reasons:
1). Too many elbows in your duct runs
2). Reducing the size of your duct runs
3). Running your gas/electric furnace blower in the on position.
This will create resistance in the hot air duct run thus causing the fuselink to melt under normal operating conditions without a power
failure.
REPLACING THE FUSE LINK:
Remove the hex nut on top of the release lid and pull the bolt down through the lid. Remove the
separated fuse link pieces and connect the new fuse link to the shaft inside the furnace heat chamber. Connect the other end of the
fuse link to the bolt that goes through the lid. Feed the bolt through the lid and replace the hex nut onto the bolt on top of the lid. As a
precaution, always have a replacement fuse link on hand.
WARNING: Never disengage the patented Heat Dump Fuse Link feature. This will void all warranties. Never put anything on top of the
release lid. The area must be kept free of any obstructions. A visual inspection by factory personnel can easily determine if the proper
steps were taken if a furnace over-heats. If the furnace is found to have been deliberately improperly operated, all warranties will be void.
