Step 2: Preparation of exodraft fan
y
Locate the installation brackets in the slots going through the fan
base part, using the bolts and nuts supplied to secure
the brackets. If
the flue diameter is larger than the chimney fan inlet, the bracket can
be installed underneath the base part. Note that the bolts must be
installed from the
bottom side.
y
Adjust the final position of the installation brackets ensuring that
there is a small gap between the brackets and the flue wall/adapter
throat.
y
Tighten the nuts. If the brackets touch the flue wall, it
may create
some vibration noise.
Step 3: Attaching the fan
y
The chimney fan is now ready for installation on the top of the
chim-
ney.
y
Place the fiber mat with the aluminum foil facing
upwards on the top
of the adapter, 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.
y
It can also be painted. It
is not necessary to bolt the fan to the chim-
ney.
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.
3.4 Single fan on brick chimney
Step 1: Prepare fan location
y
The installation procedure is the same whether the flue is round
or
square. If a clay tile flue liner is installed, it might stick up a few
inches.
Cut it back so it is flush with or no more than 1/2 inch above
the chimney crown.
y
Measure the inside diameter of the flue, cut a corresponding hole in
the fiber mat leaving a minimum distance of 3/4” to any side of
the
fiber mat.
y
The aluminum foil on the fiber mat must face upwards (against fan
base).
Step 2: Preparation of fan
y
Locate the installation brackets in the slots going through the fan
base part, using the bolts and nuts supplied to secure
the brackets.
If the flue diameter is larger than the chimney fan inlet, the bracket
can be installed underneath the base part. Note that the bolts must
be installed from the
bottom side.
y
Adjust the final position of the brackets ensuring that there is
clear-
ance between the brackets and the flue wall.
If the brackets
touch
the wall, it may generate some vibration noise.
