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 #2.
This is the minimum allowed vent pipe using 4"
stainless steel flex pipe.
The vent pipe must extend past the damper
sealing area by at least 12 inches.
Note: The fiberglass insulation must not be al-
lowed to expand to the point that it covers the end of
the flex pipe.
The chimney should be capped with any style
cap that will not allow rain or snow to enter.

#3 Installing into an existing
chimney (US only)
#4 Preferred method
This method provides excellent venting for nor-
mal operation and in a fireplace with inadaquate flue
space, or a height of over 30 feet. A 3" or 4" PL vent
pipe should be used with an optional swivel flue stub.
NOTE: The flue stub insulation wrap must still
be used with this method. See page 13, Fig. 27 &
29. With a 100% outside air kit the outside air can
be installed in the same manner as the flue pipe.
