Connecting the Gas Supply
Gas Supply Requirements
ALL INSTALLATIONS MUST COMPLY WITH LOCAL
CODE OR IN THE ABSENCE OF LOCAL CODE, MUST
COMPLY WITH THE MOST RECENT EDITION OF THE
NATIONAL FUEL GAS CODE ANSI Z223.1/NFPA 54 OR
CAN-B149.
Shut-off Valve
All codes require a gas Shut-off valve (gas cock)
and union to be installed in the supply line and in
the same room as the appliance. This allows for the
disconnection of the fireplace for servicing and main-
tenance. See Fig. 11.
The fireplace and gas control valve must be
disconnected from the gas supply piping during any
pressure testing of the system at test pressures in
excess of 1/2 psig. For pressures lower than 1/2 psig,
isolate the gas supply by closing the manual shut-off
valve.
Control Valve Connection
As mounted, the gas supply line connection is
made to the upper end of the valve. The gas sup-
ply line should be a minimum 3/8” diameter, or the
appropriate size to provide sufficient gas pressure to
the valve regardless of the input setting.
The use of flexible gas appliance connectors
is acceptable in many areas in the U.S. In Canada,
methods vary depending on local code. If local codes
permit, use flexible gas line for ease of installation
and service. For those locales where flexible gas lines
are not permitted, use the 3/8” iron fitting to make
the connection at the top side of the Control Valve.
See fig. 11.
Secure all joints tightly using appropriate tools
and sealing compounds (for propane units, be sure to
use compounds that are propane resistant). Turn on
gas supply and test for gas leaks using a 50/50 soapy
water solution or a gas detector. Never use an open
flame to check for leaks.

Final Positioning
1. Blower Power Cord:
Extend the blower power cord out forward of the
fireplace, routing it to the nearest power source.
2. Level and Plumb the Cabinet:
With the fireplace cabinet in its final position,
confirm that it is level and plumb.
Adjust the leg levelers at each corner as appro-
priate to fine-tune the level up to 1/2”. If a greater
height increase is required, the brackets can be
lowered in 1/2” increments to raise the cabinet up
to a maximum 2 1/2”.
3. Insert Height Adjustment
• Plinth:
If a Cast Iron or Wide Surround is being
installed with the a plinth option, adjust the leg
leveler brackets to raise the unit 2”.
• Scan 70i Fronts
: Adjust the leg brackets 1” or
2”, depending upon which size riser trim is being
used.
NOTE: THE APPROPRIATE MANTEL CLEARANCES
MUST BE MAINTAINED AS SPECIFIED ON PAGE 9.
IF RAISING THE INSERT MORE THAN 1/2”, INSTALL
NONCOMBUSTIBLE SUPPORT MATERIALS, SUCH
AS TILE OR PAVERS, UNDER THE CENTER OF THE
CABINET.
4. Extend the Surround Bracket Tabs:
Use pliers to bend back the Surround Bracket Tabs,
located on the forward edge of each cabinet side,
as shown in fig. 10.
• Tabs 1 and 2 bend inboard
- for use with all cast
iron surrounds, steel door facings, and the Scan
70i facing.
• Tabs 3 and 4 bend outboard
- for use with op-
tional Wide Surround Panels only.
