IMPORTANT NOTE: If propane is used, be aware
that if the tank size is too small (i.e. under
100-lbs, if this is the only gas appliance in the
dwelling. Ref. NPFA 58), there may be loss of
pressure, resulting in insuffi cient fuel delivery
(which can result in sooting or other malfunc-
tions). Any damage resulting from an improper
installation, such as this, is not covered under
the limited warranty.

Suggested Sizing of Black Iron Pipe
Schedule 40 - Pipe Supply Line
The proper gas line diameter must be used
to run from the supply regulator (at the gas
company meter) to the appliance. Never use
galvanized or plastic pipe. Refer to table 7
for suggested sizing of the gas supply line if
black iron pipe is being used.
The gas supply line should be connected to
the appliance at step 9 (page 11).
CAUTION: The fi replace in which this gas
insert is to be installed must be thoroughly
cleaned if it has been used to burn wood or
synthetic logs. Have the chimney and all
inside surfaces of the fi replace brushed and
vacuumed so that no soot, embers, or loose
combustion deposits can be drawn into the
heat circulation blower and blown into the
living area.
Step 3 UNPACK THE INSERT - Remove
the top and side cartons. Remove all the
inner packages and packing materials and
discard.
The gas supply line should be plumbed from
the fuel source to the area where the appliance
is to be installed per requirements outlined
in NFPA 54 - latest edition (USA) or B149
- latest edition (Canada).

DETAILED INSTALLATION STEPS
Step 2: PREPARATION - Plan and install gas
line. These appliances are provided with an
opening on the left hand side of the control
compartment. A 3/8" NPT gas supply pipe must
be brought near this inlet hole.
WARNING: HANDLE GLASS DOOR WITH
EXTREME CARE! THE GLASS DOOR

Gas Supply Line - We recommend that a
qualifi ed individual such as a plumber or gas
fi tter be used to correctly size and route the
gas supply line to the appliance. Installing a
gas supply line from the fuel supply to the
appliance involves numerous considerations of
materials, protection, sizing, locations, controls,
pressure, sediment, and more. Certainly no one
unfamiliar and unqualifi ed should attempt sizing
or installing gas piping.
Remove Front Glass Enclosure as Follows:
Consult your local authority having juris-
diction for requirements in your area.
Before the fi replace insert is assembled and
installed, you must consider whether the
appliance must be converted for use with
propane gas (see step 7 on Page 9). You
must also consider the vent length require-
ments.
