Venting
#3 installing into an existing
chimney
This method provides excellent venting for nor-
mal operation. This method also provides natural
draft in the event of a power failure. If the chimney
condition is questionable* you may want to install a
liner as in method #6.
*The chimney should be inspected and cleaned
before installing your stove. If you discover that
the chimney does not have a clay tile liner or has
cracks or flaking of the tile liner you will need to
install a stainless steel liner within the chimney. In
most cases the inside diameter of this liner should
be 4". Either flexible or rigid liner may be used for
this purpose. Refer to Method 6.
Be sure to design the venting so that it can be
easily cleaned.
#4 installing into an existing chimney
with optional top discharge 6" flue
adapter
This method will allow single wall 6" flue pipe to
come off the top of the stove and go directly into a
masonry or class A chimney.
This method will be desireable for people who are
replacing a wood or coal stove and have an existing
chimney to use.
