•Whenplanningtheinstallationofyourfurnace,keepinmind
that condensation is detrimental to exhaust systems. Bio fuels
have a high moisture content and can be more susceptible to
condensation forming in certain types of installations. Install
the furnace with minimum piping exposed to the cold tem-
peratures outside the PL envelope of the house.
•Checkwiththemanufacturerofyourventingsystemtosee
that they honor the warranty of their PL vent with the use of
corn and other bio fuels.
•
The longer the vent pipe and the more elbows that
are used, the greater the flow resistance. Each elbow
or tee is equal to 5 feet of straight pipe. Because of
this we recommend using as few elbows as possible
and a maximum of 20 feet of piping. It is recom-
mended that the vent system be installed with a
minimum of three feet (3') of vertical rise above the
exhaust port on the back of the furnace. It is recom-
mended to get the vertical rise while still in a heated
area to reduce exterior piping. Failure to provide the
natural draft that results from a vertical rise may
result in smoke being released into the house when
electricity to the unit is interrupted while burning or
smoldering fuel remains in the burn pot.
•Approvedcorn/pelletfurnaceventingmaterialsare:
1) PL vent, a double wall vent with a stainless steel liner
2) Single wall rigid or flexible stainless steel pipe. In this
manual, approved venting will be referred to as a “PL
vent” or “single wall vent.”

within a chimney).
•
A clean out “tee” (PL vent or “quick-Connect Ex-
haust”) must be installed directly to the furnace and
at the bottom of each vertical run of the exhaust
system. These tees are to assist in periodically clean-
ing the pipe. Single or double clean-out tees may be
used.

If vented horizontally, joints should be made gas
tight in a manner that should be specified.
NOTE: Adhere to PL vent clearance to
combustibles as required. Strictly observe
manufacturers guidelines.
NOTE: Type “B” gas vent must not be used in
the installation of this furnace. The exhaust must
be installed so the entire system can be cleaned
without disassembly.

CAUTION:
• Installation is to be performed by a qualified installer or dealer.
• Adhere to all clearances specified by the manufacturer of the venting system used.
• Adhere to all clearances specified in the installation instructions of this furnace.
• Do not install this unit in a sleeping room.
NOTE: Condensation from a bio furnace is detrimental to the venting system. Only buy
venting systems that are warranted with burning corn and other bio fuels.
