RECOMMENDED HEIGHTS FOR WOODSTOVE FLUE
Simple rules on draft. See Table 1.
1) At sea level minimum height is 12' straight.
2) Add the following vertical height to compensate for:
45 deg. elbow = 1 ft.
90 deg. elbow = 2 ft.
"T" = 3 ft.
Each foot of horizontal run = 2 ft.
3) Add 4% overall for each 1000' above sea level.
Example: a)
1-1/2 ft. of horizontal run = 3 ft.
one "T" = 3 ft.
Total Addition (at sea level) = 6 ft.
Example: b)
One 90 deg. elbow = 2 ft.
2 ft. of horizontal run = 4 ft.
one "T" = 3 ft.
Total Addition (at sea level) = 9 ft.

WARNING:
DO NOT INSTALL IN SLEEPING
ROOM
CAUTION: The structural integrity of the mobile home
oor, wall and ceiling/roof must be maintained.
Draft is the force which moves air from
the appliance up through the chimney.
The amount of draft in your chimney
depends on the length of the chimney,
local geography, nearby obstructions and
other factors. Too much draft may cause
excessive temperatures in the appliance
and may cause damage. An uncontrollable
burn or excessive temperature indicates
excessive draft. Inadequate draft may
cause back pung into the room and
plugging of the chimney. Inadequate
draft will cause the appliance to leak
smoke into the room through appliance
and chimney connector joints. Ensure
the heater is installed in areas that are
not too close to neighbors or in valleys
that would cause unhealthy air quality
or nuisance conditions.
