It is best to frame your fireplace after it is positioned and the vent system installed. Use 2x4’s and frame
to local building codes.
To install the fireplace facing flush with the finished wall, position the framework to accommodate the
thickness of the finished wall.
It is not necessary to install a hearth extension with this fireplace system.
The junction box should be wired to the electrical system at the time of installation of the fireplace.
Wiring must be performed by a qualified person in a manner to conform with National Electrical Code
ANSI/NFPA 70 and all applicable local codes.
CAUTION: ALWAYS CHECK AND MAKE SURE POWER IS OFF BEFORE ATTEMPTING TO INSTALL OR SERVICE ANY ELECTRICAL
WIRING OR COMPONENTS.
FRAMING INSTRUCTIONS 7
When the fireplace is installed directly on carpeting, vinyl tile or other combustible material (other than
wood flooring) it shall be installed on a metal or wood panel extending the full width and depth of the
fireplace.
Provide adequate ventilation air.
Provide adequate accessibility clearance for servicing and operating the fireplace.
Never obstruct the front opening of the fireplace.
Clearance to Combustible Construction. See Figure 2.
Sides - 1/2 inches Top - 0 to Top of Spacers Bottom - 0 inches
Back - 1/2 inches Front - 37 inches
FIGURE 2
53D9019. Rev 3 11/07

To accommodate the various configurations, we have provided access openings in the bottom of the
unit for gas line and wall switch wires. This may not be convenient for some installations, if so you may
drill an access opening into the lower face of the unit (1" for gas line, 1/2" for the grommet).
1. Route the 3/8 inch N.P.T. black iron gas line or equivalent to the fireplace. Include a manual shut-off
valve and union in the line so the control may be disconnected for servicing. A drip leg is also
recommended in the gas supply line.
2. Install a rigid black pipe or if local codes permit a 3/8 inch flex connector and shutoff valve to the gas
line and the fireplace gas valve. Seal and tighten securely. An adapter fitting is required between the
gas valve and flex connector if used. Do not kink flex connector (Figure 3).
3. Check for gas leaks with a soap and water solution. DONOT USE AN OPEN FLAME.
NOTE: PURGE ALL GAS LINES WITH THE GLASS DOOR OF THE FIREPLACE REMOVED. ASSURE THAT ACONTINUOUS GAS
FLOW IS AT THE BURNER BEFORE INSTALLING THE DOOR.
