Installing Chimney/Vent System Continued
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
or tall buildings. Areas with high winds also frequently require
higher than normal chimneys.
Certain styles of architecture tend to interfere with a
draw. If the room in which the
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
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.
