Connecting the Combustion Fan
The combustion fan (AD-MF) is responsible for moving the air
throughout your stove and is mounted on the exhaust of your Catalyst
in the section of single wall chimney connector pipe directly adjacent
to the stove.
Catalyst’s combustion fan is mounted in your existing single wall chimney pipe.
You will need a dremel or jigsaw, drill, a pair of scissors, and a flat head
screw driver for your installation.
CAUTION: The combustion fan must be mounted on a piece of
single wall chimney connector pipe. Do not mount the
combustion fan on double walled pipe.
The combustion fan may be mounted on vertical, horizontal or
inclined chimney connector pipe. If used on a horizontal chimney,
mount fan on bottom of pipe, not on top, to avoid creating a heat
trap in inducer. The combustion fan motor shaft must be mounted
horizontally to prevent motor bearing wear. The combustion fan
should be mounted at least 12” from the top surface of Catalyst.
Chimney connector pipe downstream of the combustion fan
should be hermetically sealed to prevent smoke leakage. Avoid
the use of tee connections downstream of the combustion fan.
