Contour Pellet Stove
1. Chimney & Connector: Use 3" (76mm) or 4" (102mm) diameter type "L" or "PL" venting system.
2. Mobile Home: Approved for all listed pellet vent. If using the 3" (76mm) vertical Top Vent Adapter Kit (part #811-0860), or the 3"
(76mm) to 6" (152mm) Offset Collar (part #812-3570), use listed double wall ue connector. An Outside Air Kit (part #811-0871),
must be used with manufactured home installation.
3. Residential: The 3" (76mm) vertical Top Vent Adapter Kit (#811-0860), and 3" (76mm) to 6" (152mm) Offset Collar (part #812-3570),
are tested to use 24 gauge single wall ue connector or listed double wall ue connector to Class A listed metal chimneys, or masonry
chimneys meeting ICBO standards for solid fuel appliances.
4. The stove is approved for all 3" (76mm) or 4" (102mm) diameter listed pellet vent. It can be either vertically or horizontally vented.
5. Install vent at clearances specied by the vent manufacturer.
6. Be sure to secure exhaust venting system to the stove with at least three set screws. Also secure all connector pipe joints
with at least three screws through each joint.
NOTE: All pipe must be sealed using welded seam pipe whenever possible. Seal pipe joints with high temperature silicone
(500°F [260°C] minimum rated only).
1. Do not terminate vent in any enclosed or semi-enclosed area such as a carport, garage, attic, crawl space, under a sun
deck or porch, narrow walkway or closely fenced area, or any location that can build up a concentration of fumes such as a
stairwell, covered breezeway, etc.
2. Vent surfaces can get hot enough to cause burns if touched. Noncombustible shielding or guards may be required.
3. Termination must exhaust above air inlet elevation. It is recommended that at least 5' (1.5m) of vertical pipe be installed when
appliance is vented directly through a wall. This will create a natural draft, which will help prevent the possibility of smoke or odor venting
into the home during appliance shutdown. It will also keep exhaust from causing a nuisance or hazard by exposing people or shrubs to
high temperatures. The safest and preferred venting method is to extend the vent vertically through the roof.
4. Venting should terminate not less than 4' (1.2m) below, not less than 4' (1.2m) horizontally from, and not less than 1' (305mm) above
doors and windows, or gravity or ventilation air inlets into the building.
5. Distance between bottom of termination and grade should be 1' (305mm) minimum. This is conditional upon plants in the area,
and nature of grade surface. The grade surface must be a noncombustible material (i.e., rock, dirt). Distance between bottom of
termination and public walkway should be 7' (2.1m) minimum.
6. Distance to combustible materials should be 2' (51mm) minimum. This includes adjacent buildings, fences,
