#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 approved
pellet vent pipe fittings. Seal pipe joints with silicone
in addition to the sealing system used by the manu-
facturer. 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 chim-
ney 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.
