Step 3: Attaching the fan
y
The chimney fan is now ready for installation on the top of the
chim-
ney.
Place fiber mat with the aluminum foil facing upwards on
the
top of the chimney, and place the fan on top of the mat.
y
High temperature silicone can be applied on the side of the
mat,
but
is not required. It can also be painted.
y
It is not necessary to bolt
the fan to the chimney.
Step 4: Sealing the slots
y
To avoid rainwater to enter the chimney the 4 slots must be sealed with silicone.
CAUTION
Under conditions with extremely strong winds surrounding the top of the chimney, the chimney
fan must be secured by steel wires supplied with the fan.
3.5 Multiple fans on steel chimney
y
If two or more chimney fans are required to create sufficient draft,
installation procedures are the same as for single
fan installation on
a steel chimney.
The only difference is that the
fans are sitting next
to each other on the top of the chimney. A spe-
cial adapter plate
is required (14 GA or thicker).
y
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 (1) motor speed control.
3.6 Multiple fans on a brick chimney – oversized flue
y
If two or more fans are required to create sufficient draft, a special
adapter plate is required.
The adapter plate should be made of
stainless steel (14 GA or thicker), depending on the size and the fan
models used.
y
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 (dimension “B” in 1.5. Dimensional data).
y
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 tan-
dem by one (1) motor speed control.
y
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.
