Venting
#6 Installing into an existing fireplace
chimney ( US and Canada )
This method provides excellent venting for nor-
mal operation. This method also provides natural
draft in the event of a power failure.
In Canada and some places in the US it is re-
quired that the vent pipe extend all the way to the top
of the chimney.
In this method a cap should also be installed
on the chimney to keep out rain. Be sure to use ap-
proved pellet vent pipe fittings. Seal pipe joints with
silicone in addition to the sealing system used by
the manufacturer. Pipe size should be increased to
4" using this method.
#7 Installing into an existing
chimney ( US and Canada )
This method provides excellent venting for nor-
mal operation. This method also provides natural
draft in the event of a power failure.
In Canada and some places in the US it is re-
quired that the vent pipe extend all the way to the top
of the chimney. The pipe or liner inside the chimney
should be 4"diameter.
In this method a cap should also be installed
on the chimney to keep out rain. One disadvantage
of this method is that it is harder to clean the vent
pipe, therefore, there is a tendancy not to do it as
often as needed.
