FREESTANDING INSTALLATION
Additional Venting Information
Do not mix and match components from different pipe manufacturers when assembling your venting system (i.e. Do NOT use venting pipe from one manufacturer and a thimble from another).
We require a minimum vertical rise of 36 in. (3 ft.) of pipe to create natural draft in the system, which helps evacuate smoke from the stove in the event of a power failure or combustion blower failure.
Venting systems 15.0 ft. or shorter may be composed entirely of 3.0 in. pellet pipe; to reduce frictional losses, venting systems longer than 15.0 ft. should be composed of 4.0 in. pellet pipe.
Do not terminate the venting system directly beneath any combustible structure such as a porch or deck.
Follow NFPA 211 rules listed below for venting system termination location relative to windows and other openings in the dwelling.
o NFPA 211 (2003 ed.) Section 10.4 Termination: 10.4.5
(1)The exit terminal of a mechanical draft system other than direct vent appliances (sealed combustion system appliances) shall be located in accordance with the following:
(a) Not less than 3 ft. (.91 m) above any forced air inlet located within 10 ft. (3.0m).
(b) Not less than 4 ft. (1.2 m) below, 4 ft. (1.2 m) horizontally from or 1 ft. (305 mm) above any door, window or gravity air inlet into any building.
(c) Not less than 2 ft. (0.61 m) from an adjacent building and not less than 7 ft. (2.1 m) above grade when located adjacent to public walkways.
Distance between the termination opening and grade should be a minimum of 24 in. contingent on the grade surface below the termination. When determining the termination height above grade, consider snow drift lines and combustibles such as grass or leaf accumulation. In areas where significant snowfall is possible, the termination height must be sufficiently high to keep the termination free of snow accumulation.
