Notes on termination of Vent Pipe (see also “FLUE SYSTEM” section of manual):
1. Not less than three (3) feet above any forced air inlet located within ten (10) feet.
2. Not less than four (4) feet below, four (4) feet horizontally from, or one (1) foot above any door,
window or gravity air inlet into any building.
3. Not less than two (2) feet from an adjacent building, and not less than seven (7) feet above grade
where located adjacent to public walkways.
The exhaust exit shall be arranged so that the flue gases are not directed so that it will affect people,
overheat combustible structures, or enter buildings. Forced draft systems and all parts of induced
draft systems under positive pressure during operation shall be installed gastight or to prevent leakage
of combustion products into a building. Through-the-wall vents shall not terminate over public
walkways, or where condensate or vapor could create hazards or a nuisance.
Be sure to follow local codes and all manufacturer’s instructions (including exhaust pipe).
Consult a professional installer and/or call Customer Service if you have any questions.

GUIDELINES FOR EXHAUST VENTING SYSTEMS DESIGN
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER
• A UL listed three-inch or four-inch (3”or 4”) type “PL” pellet vent exhaust system must be
used for installation and attached to the pipe connector provided on the back of the unit.
Use a three-inch to four-inch (3” to 4”) adapter for four-inch (4”) pipe. A cap must be used
at the termination of type “L” vent chimneys. Four-inch (4”) PL is recommended for
elevations above 2,500 feet above sea level.
• Do not terminate vent in any enclosed or semi-enclosed area, such as: carports, garage,
attic, crawl space, under a deck or porch, walkway or close area or any location that
could build up a concentration of fumes such as a stairwell, covered breezeway, etc.
• Vent surfaces can get hot enough to cause burns if touched by children. Non-
combustible shielding or guards may be required.
• Do not install a flue damper in the exhaust vent of this unit.
• Termination must exhaust above air inlet elevation. Installation MUST include three (3)
vertical feet of pellet vent pipe. This will create some natural draft to prevent the
possibility of smoke or odor during unit shutdown, and keep exhaust from causing a
nuisance or hazard from exposing people or shrubs to high temperatures. DO NOT
CONNECT THIS UNIT TO A CHIMNEY FLUE SERVICING ANOTHER APPLIANCE. DO
NOT CONNECT DIRECTLY TO A MASONRY CHIMNEY.
• Distance from doors and windows, gravity or ventilation air inlet into building: not less
than four feet (4 ft.) below, four feet (4 ft.) horizontally from, one foot (1 ft.) above (this
does not apply if the windows are non-opening or have been fixed so they cannot open).
