VENTING REQUIREMENTS
Install vent at clearances specifi ed by the vent manufacturer. 
Do not connect the pellet vent to a vent serving any other appliance or stove.
Do not install a fl ue damper in the exhaust venting system of this unit.
The following installation guidelines must be followed to ensure conformity with both the safety listing of this stove and 
to local building codes. Do not use makeshift methods or compromise in the installation.
IMPORTANT!  This unit is equipped with a negative draft system that pulls air through the burn pot and 
pushes the exhaust out of the dwelling. If this unit is connected to a fl ue system other than the way explained 
in this manual, it will not function properly.
MAXIMUM VENTING DISTANCE
Installation MUST include at least 3-feet of vertical pipe outside the home.  This will create some natural draft to reduce the 
possibility of smoke or odor during appliance shutdown and keep exhaust from causing a nuisance or hazard by exposing 
people or shrubs to high temperatures.  The maximum recommend vertical venting height is 12-feet for 3-inch type “PL” 
vent. Total length of horizontal vent MUST NOT exceed 4-feet.  This could cause back pressure.  Use no more than 180 
degrees of elbows (two 90-degree elbows, or two 45-degree and one 90-degree elbow, etc.) to maintain adequate draft.
PELLET VENT TYPE
A UL listed 3-inch or 4-inch type “PL” pellet vent exhaust system must be used for installation and attached to the pipe 
connector provided on the back of the stove (use a 3-inch to 4-inch adapter for 4-inch pipe).  Connection at back of 
stove must be sealed using Hi-Temp RTV.  Use 4-inch vent if the vent height is over 12-feet or if the installation is over 
2,500 feet above sea level.
We recommend the use of Simpson Dura-Vent
®
 or Metal-Fab
®
 pipe (if you use other pipe, consult your local building 
codes and/or building inspectors).  Do not use Type-B Gas Vent pipe or galvanized pipe with this unit. The pellet vent 
pipe is designed to disassemble for cleaning and should be checked several times during the burning season. Pellet 
vent pipe is not furnished with the unit and must be purchased separately.
PELLET VENT INSTALLATION
The installation must include a clean-out tee to enable collection of fl y ash and to permit periodic cleaning of the exhaust 
system.  The clean-out tee must be installed at the base of the vertical section, not in horizontal section. 90-degree 
elbows accumulate fl y ash and soot thereby, reducing exhaust fl ow and performance of the stove.  Each elbow or tee 
reduces draft potential by 30% to 50%.
All joints in the vent system must be fastened by at least 3 screws, and all joints must be sealed with Hi-Temp RTV 
silicone sealant on the inside and high temperature tape on the outside to be airtight.  The area where the vent pipe 
penetrates to the exterior of the home must be sealed with silicone or other means to maintain the vapor barrier between 
the exterior and the interior of the home.
Vent surfaces can get hot enough to cause burns if touched by children. Noncombustible shielding or guards may be 
required.
PELLET VENT TERMINATION
Do not terminate the vent in an enclosed or semi-enclosed area, such as; carport, garage, attic, crawl space, under a 
sundeck or porch, narrow walkway, or any other location that can build up a concentration of fumes.
The termination must exhaust above the outside air inlet elevation.   
The termination must not be located where it will become plugged by snow or other materials.
Do not terminate the venting into an existing steel or masonry chimney.
