Figure 7.1
Model HD5030TV is approved to be used with 10" B-Type Gas Vent. Under most conditions the 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 gases 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).
3. The 10' Rule of Thumb is a guide for calculating chimney height that works under most conditions. However,
many factors can cause the need for additional chimney height beyond what 10' Rule of Thumb would indicate.
Topographical factors can cause high-pressure zones, which prevent a chimney from drawing. This can occur if
the house is located in a low-lying area, in a valley or near the base of a cliff or hillside. The same situation can
occur if the chimney is near other steep rooflines or tall buildings. Areas with high winds also frequently require
higher than normal chimneys.
Certain styles of architecture tend to interfere with a fireplace's draw. If the room in which the fireplace is located
has a very high ceiling, flue gasses may enter the room unless the chimney is terminated at a level higher than
that of the ceiling, even if the 10' Rule of Thumb indicates a shorter chimney height.
Note: Installations which will not allow the 10' rule to be followed must be submitted to Golden Blount Inc. for
approval. 1-800-833-1139.
Warning! This gas appliance must not be connected to a chimney flue serving a separate solid-fuel burning
appliance.
