PROPER BURN PRACTICES
FOR MAXIMUM EFFICIENCY AND SAFETY!
• The chimney is one of the most important elements of the furnace. If the chimney is not
connected properly and installed according to manufacturer’s specification and national
and local codes, the unit is not safe and will not burn efficiently. Lack of proper chimney
installation will cause unit to produce more smoke and less heat output. See Pages 7-9
of this manual to ensure proper installation.
• Wood that is properly cut and stored to dry will produce more BTUs and higher heat
output than wood that has a higher moisture content. Wood with higher moisture
content will create creosote in the chimney and cause flue fires. See Pages 10 and 13 for
proper wood handling practices.
• There should be no alteration of the Fire Chief Furnace in any way, as this will void the
UL391 listing and affect the operation of the furnace. This will also void the warranty of
the unit.
• Fire Chief Furnace makes two types of units, indoor as well as outdoor furnaces. The
indoor units are manufactured and tested for indoor applications only. They are not
meant to go outside the house but must be placed indoors in a basement or utility room.
Any indoor unit placed outside the home in a shed or building, will void warranty, violate
the safety listing, and will not produce the maximum efficiency possible with this unit.
For outdoor applications please use units FCOS1800D and FCOS2200D.
