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.
