Installing Chimney/Vent System
Model SF3624TV is approved to be used with 8" B-Type Gas Vent or 8" class-A All Fuel Chimney. 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 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).
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, smoke 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.
Note: A draft hood is installed and is in the same atmospheric pressure zone as the combustion air inlet to the
appliance and is located so that the relief opening is accessible for checking vent operation.

If your plans do not allow for the venting system as outlined
previously in the "Installing chimney/vent system" section, you may
contact ENERVEX, Inc. (formerly EXHAUSTO) at 800-255-2923.
They will design an approved venting system to suit your venting
needs. These power vented systems follow the standards and codes
as outlined under the NFPA 54/ANSI Z223.1 Nation Fuel Gas Code.
Please check with the local authority having jurisdiction in your area.
The engineers at ENERVEX are familiar with Golden Blount
fireplaces and their systems will allow you to minimize the amount
of vent pipe exposed outside of your home. Fireplaces may also be
horizontally vented with these systems.
