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 be deliberately improperly used, all warranties will be void.
To order a replacement Fuse Link (Part # FCFL370): call 1-800-875-4788.
One replacement fuse link was included in the hardware pack for your furnace.
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 turn 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.
