Step 3: Attaching the fan
y The chimney fan is now ready for installation on the top of the chim-
ney. Place ber 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 sucient draft, installation procedures are the same as for single
fan installation on a steel chimney. The only dierence 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 ue
y If two or more fans are required to create sucient 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 ue size exceeds the fan
base dimensions. The adapter plate should be sized so it covers the
ue and secured. A hole should be cut in the center of the plate and
the fan mounted centered over the hole.
