D. Venting Into an Existing Fireplace and Chimney
You can vent your Franklin Gas Fireplace into an open fireplace
by running two flexible ducts up the length of the chimney. One
duct will carry the exhaust gases to the top of the chimney while the
other duct brings fresh air into the stove for combustion. See
illustration 6.5.
Note: Each additional elbow reduces the maximum rise by 3 feet.
Refer to the Simpson Dura-Vent instructions regarding installation
of your Direct-Vent system.
E. Venting Into an Existing Masonry or Prefabricated Metal
Chimney (Vertical installation only).
You can vent your Franklin Gas Fireplace into an existing
chimney by running a flexible duct up the length of the chimney.
This 4” duct will carry the exhaust gases to the top of the chimney.
The surrounding chimney area is utilized to bring fresh air into the
stove for combustion.
Venting into a masonry chimney requires a conversion kit, 4”
duct, and a cap. See illustration 6.7 on page 11. Venting into an
existing prefabricated metal chimney requires a conversion kit
specific to the brand of chimney installed, a 4” duct, and a cap. See
illustration 6.6 for more detail.
Note: You cannot install a Conversion Kit in a through-the-wall
type factory-built metal chimney.
ALL VENT CLEARANCES MUST BE MAINTAINED.
CHECK YOUR VENT CLEARANCES AGAINST THE
ILLUSTRATIONS ON PAGE 9.
