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
floor, 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 un-
controllable burn or excessive temperature indicates
excessive draft. Inadequate draft may cause back
puffing into the room and plugging of the chimney.
Inadequate draft will cause the appliance to leak
smoke into the room through appliance and chim-
ney 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.
