Installing Chimney/Vent System
fireplace system will draw properly if the chimney height is determined in accordance with the following guidelines:
Note: (90-degree elbows are not approved! Maximum offset angle must not exceed 45 degrees.) Many
manufacturers of B-Type gas vent offer “High Performance,” or “High Wind” caps. These caps limit the
outlet area for flue gasses to expel and should not be used with this fireplace. In the event of draft related
problems due to extreme wind conditions, a special wind ring is available.
1.
If your chimney penetrates the roof within 10' of its peak, it must be extended at least 24" above your roof’s
peak and be at least 36" above the highest point of the roof opening, (see below).
2.
If the chimney penetrates the roof farther than 10' from its peak, measure from the centerline of the chimney to
a point 10' away, between the chimney and the peak of the roof. The top of the chimney must be at least 36"
above the highest point of the roof opening, (see below).
