Step 1: Gather the combustion fan parts
Each Catalyst comes with a combustion fan, four “U” nuts, four screws,
rope gasket, and a paper template cutting your chimney connector.
Catalyst does not come with the screws necessary to secure your
chimney connector pipe to your stove or to the remainder of your
chimney connector.
Step 2: Clean pipe surface and adhere the template to your pipe
Ensure the chimney connector pipe is clean and adhere the template
so that the arrow points towards the chimney exit. For best
appearances, adhere the template so that the hole for the combustion
fan is on the back latch side of the stove.
Step 3: Drill and cut the chimney connector pipe
Drill four 7/32” diameter holes where indicated on the template. Cut the
pipe along the dashed line using a dremel tool or jigsaw.
Step 4: Attach “U” nuts to the mounting pipe and apply rope
gasket around the edges of the flange
Press each “U” nut over the holes on the cutout of the side of the pipe
such that the flat side of the nut is on the exterior of the pipe. Remove
the paper backing from the gasket tape and press firmly to adhere to
the edges of the mounting pipe.
Step 5: Secure combustion fan to mounting pipe
Insert the curved edge of the combustion fan housing into the mounting
pipe in direction of airflow. The curved edge can be flexed if need be
to get a proper fit. Secure to pipe with the four screws.
