Multiple fans on chimney
If two or more chimney fans are required to create sufficient draft, installation procedures are almost the
same as for single fan installation. See the installation guide below.
Multiple fans on a brick chimney
1
If two or more fans are required to create suffi-
cient draft, a special adapter plate is required
(not an Exodraft part). The two holes in the plate
should match the throat diameter of the fan
model used and the distance from center to center
should be at least equal to the fan width. Exodraft
recommends that a partition is mounted between
the fans.
The adapter should be sealed with silicone and
bolted onto the top.
When installing multiple fans, it is extremely
important that the fans are of the same model
and size, and they must be controlled in tandem
by one motor speed control.
A similar approach should be taken if the flue size
exceeds the fan base dimensions. The adapter
plate should be sized so it covers the flue and
secured. A hole should be cut in the center of the
plate and the fan mounted centered over the hole.
Multiple fans on a steel chimney

If two or more chimney fans are required to create
sufficient draft, the installation procedures are
basically the same as for single fan installation
on a steel chimney. However, as the fans will be
placed next to each other, a special plenum box
will be required (not an Exodraft part).
Exodraft recommends that a partition is mounted
between the fans.
