2. Installing the Chimney Fan
Transport Safety Device
If a transport safety device is present, remove it from the
vane and make sure that the vane can revolve without
hindrance.
RS 14/16: Before mounting, the transport safety device on
the hinges must be removed.
2.1 Single Fan on Steel Chimney
Step 1: Prepare fan location
If a stack cap is already installed, it must be removed. The
steel adapter (FRS) slides right into the chimney, where the
long collar engagement ensures safe anchoring. If
necessary, the adaptor can be secured by means of long
self-tapping stainless steel screws into the side of the collar
through the chimney wall.
Measure the inside diameter of the flue and cut a
corresponding hole in the center of the fiber mat. If the flue is
so big that the throat in the adapter has been reduced to fit
the throat of the fan, the hole in the fiber mat should
correspond to the throat.
The aluminum foil on the fiber mat must face upward (against
fan base).
Step 2: Preparation of fan
Locate the installation brackets in the grooves on the under
side of the fan base, using the bolts and nuts supplied to
secure the brackets. Note that the bolts shall be
installed from the bottom side in the two inner holes.
Adjust the final position of the installation brackets
ensuring that there is a small gap between the brackets
and the flue wall/adapter throat. Tighten the nuts.
If the brackets touch the flue wall, it is likely to create some
vibration noise.
Step 3: Attaching the fan
The chimney fan is now ready for installation on the top of the
chimney. 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.
If extremely strong winds constantly surround the top of the
chimney, the chimney fan must be secured by using two
safety wires.
Caution: Under conditions with extremely strong
winds constantly surrounding the top of the
chimney, the chimney fan must be secured by steel
wires or similar.
