VENTING REQUIREMENTS

Install vent at clearances specified by the vent manufacturer.
Do not connect the pellet vent to a vent serving any other appliance or stove.
Do not install a flue 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.
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 flue 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. 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 peo-
ple 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. 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). 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
ing 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 fly ash and to permit periodic cleaning of the
exhaust system. 90-degree elbows accumulate fly ash and soot thereby reducing exhaust flow 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 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.
