Vent Termination

INSTALLATION

Do not terminate vent in an enclosed or semi-enclosed area such as: carports, garage, attic, crawl space, under a deck, porch, narrow walkway, closely fenced area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway etc.

Vent surfaces can get hot enough to cause burns if touched. Adults should supervise children when they are in the area of a hot stove. Non-combustible shielding or guards may be required.

Termination Cap: The termination of the outside chim- ney of the pellet stove shall be located in accordance with the following:

A.Higher than 3’ (.92m) above any forced air inlet (air conditioner, etc.) located within 10’ (3m).

B.Not less than 4’ (1.2m) below, 4’ (1.2m) horizontally from or 1’ (3.1m) above any gravity air inlet (door, window, etc.) which flue gases could re-enter the dwelling.

C.Not less than 2’ (.6m) from combustible materials such as an adjacent buildings, fences, protruding parts of the structure, roof overhang, plants and shrubs, etc. and not less than 7’ (2.1m) above grade when located adjacent to the public sidewalks (ac- cess). The final termination of the exhaust system must be configured so that flue gases do not jeop- ardize the safety of people passing by, overheat combustible portions of nearby structures or enter the dwelling.

D.Not less than 3’ (.92m) below an eave (maximum overhang of 3’ (.92m) or any construction that pro- jects more than 2” (51mm) from the plane of the wall.

E.The distance from the bottom of termination to grade is 12” (305mm) minimum. This is conditional upon plants and nature of grade surface: Be careful to choose a location for the vent termination which does not expose people or shrubs to high heat from the exhaust gases. The exhaust gases are not hot enough to ignite grass, plants and shrubs located in the vicinity of the termination although they should be a minimum of 3’ (.92m) away. The grade surface under the termination must not be a lawn.

F.Since sparks may escape from the exhaust pipe of any stove, use caution when positioning the vent pipe. Refer to pipe manufacturer’s instructions when installing and terminating the exhaust. The vent pipe should be horizontal and never run the pipe in a downward direction (recommend a 1/4” (7mm) rise per foot horizontal).

Notes:

•It is not recommended to terminate exhaust vent on the prevailing wind side of the house.

•It is not recommended using a termination cap with a screen (fly ash can collect in a screen re- sulting in blockage).
