#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.
