VENT TERMINATION
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).

Chimney Height Requirements
The vent termination height required is - USA, 1-foot
minimum; Canada 3-feet minimum above the roof pene-
tration point as illustrated below (Ref. USA - National
Standard, NFPA 211, Clause 7-4.1 and Canada National
Standard CSA B365-01, Clause 5.6). Check with your
local building official for additional requirements for your
area.
Manufactured (Mobile) Home
Chimney Height Requirements
The chimney must extend 3’ (.92m) above the level of
roof penetration and a minimum of 2’ (.61m) higher than
any roof surface within 10’ (3m) (see below). Check with
your local building officials for additional requirements for
your area.
To pass inspection in nearly any jurisdiction, the chimney
must meet both safety and exhaust flow requirements.
The (3’ by) 2’ by 10’ rule applies to both masonry and
factory built chimneys.
* Ref. NFPA 211 Clause 7 – 4.1.2, Vents installed with a
listed cap shall terminate in accordance with the terms
of the cap’s listings.
