INSTALLATION

Insert Venting
WARNING: This appliance is equipped with a safety control
system designed to protect against improper venting of combus-
tion products. Operation of this heater when not connected to
a properly installed and maintained venting system or tamper-
ing with the blocked vent shut-off system can result in carbon
monoxide (CO) poisoning and possible death.
Insert must be vented to the outside in accordance with the current edition
of the National Fuel Gas Code ANSI-Z223.1-latest edition, also known
as NFPA 54 (In Canada, the current CAN/CSA B149.1 installation code).
The insert must not be connected to a chimney flue serving a separate
solid fuel burning appliance.
This gas insert requires a 4" diameter B-vent or listed flex aluminum
or stainless chimney liner extending the entire length of the chimney to
ensure proper operation. The vent should terminate with a chimney cap
or rain cap. Chimney should be sealed around cap to prevent air and rain
from entering chimney. Adhere to vent manufacturer's instructions for
installation and vent termination.
The insert must be installed so the
draft hood is in the same atmospheric
pressure zone as the combustion air
inlet to the appliance.
Flue Collar Connection
This insert has a detachable flue col-
lar to ease installation. To detach flue
collar, unscrew the draft tube retaining
screw and slide draft tube and flue
collar to the rear. Attach flue collar
(with 3 sheet metal screws or a B-vent
connector) to vent pipe previously
installed in chimney. As the insert is
pushed into fireplace, guide draft tube
and flue collar into the guide brackets
until draft tube retaining screw can be
reinstalled in its original hole.
