LOCATION
Where you install the furnace will have an effect on the
insulated, installing the furnace outdoors will mean some
heat loss at the furnace. The furnace will have less heat loss
when installed indoors away from the elements that can
cause heat loss.
Maintain an adequate clearance of buildings and
combustibles.
Do not place or store wood within stove installation
clearances or within the space required for charging
and ash removal.
Do not store combustible fuels in the same room as the
furnace.
Pile and store wood under shelter.
For indoor installations where fans are used in the fuel
storage area, they should be installed so as to not create
any negative pressure in the room where your furnace is
burning.
Contact all governing authorities in your area prior to
installation.
When choosing the location of your furnace you should
consider prevailing wind direction, distance from home
and wood storage for refueling.
Give consideration to any effect on your neighbors.
CLEARANCES TO COMBUSTIBLES
Whether installing your G SERIES furnace inside a building
or outside, the following clearances to combustibles must
always be followed or damage and personal injury may
result.

FURNACE INSTALLATION GUIDE
Installation should be performed by a qualified installer and must comply with all requirements of the agency having
jurisdiction.
U.S. ENVIRONMENTAL PROTECTION AGENCY Certified to comply with the 2020 particulate emission standards.
Annual Efficiency rating is calculated using the weighted average test results from the emission test reports for each model.
Efficiency is determined by dividing the total input using the heating value of wood (8600BTU/lb)by the actual heat delivered
by the furnace.
