NEVER LOCATE INLET IN GARAGE OR ANY AREA WHERE THERE IS ANOTHER FUEL BURNING APPLIANCE OR PRODUCTS EMITTING COMBUSTIBLE GASES SUCH AS PAINT, GASOLINE, ETC. IN COLD CLIMATES, IT IS RECOMMENDED THE COMBUSTION AIR DUCT BE INSULATED. Outside combustion air ducting may be run upwards or vertically through framing and ceiling joists, with the hood installed through an outside wall and 3' (1 m) below the B-Vent termination. Ducting may also be run downward through floor joists and under the home to a ventilated crawlspace not considered part of the living area of the home. Note:Do not terminate combustion air kit in attic space under any circumstances. After completing the installation of the optional combustion air vent system the actuator arm must be put in service and tested to ensure proper operation before completing any enclosure around the firebox. Failure to do so may result in extensive and costly rework. Operate the actuator through several cycles including the closed position. Ensuring proper operation and freedom of movement. Return the actuator arm to the closed position. Step 8. Installing Logs and Rockwool – The logs are packaged within the firebox. The bag of rockwool is in the lower control compartment. Refer to the Homeowner's Care and Operating Instructions for detailed placement instructions for the logs and rockwool. Step 9. Optional Glass Doors/Enclosure Panel Availablity, Precautions and Instructions – See the Homeowner's Care and Operating Instructions for a selection of glass doors/enclosure panels available for installation in these appliances. Installation Instructions for the doors/enclosure panels are provided with them. • Never clean glass when doors or panel are hot due to operating the appliance. • Glass and metal frames get hot. Use only the wooden handles to open and close the doors or to lift out panel. CAUTION: THE APPLIANCE SHOULD ONLY BE OPERATED WITH THE GLASS DOORS FULLY OPEN OR FULLY CLOSED.

Checking the System – With gas line installed, run initial system checkout before closing up the front of the unit. Follow the pilot lighting instructions provided in the Homeowner's Care and Operation Instructions. For piezo ignitor location see Figure 24 on page 11(millivolt appliances only). NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE. Note:Lighting instructions are also found on the pull-out label attached near the gas valve in the control compartment. When first lighting the appliance, it will take a few minutes for the line to purge itself of air. Once purging is complete, the pilot and burner will light and operate as indicated in the instruction manual. Subsequent lightings of the appliance will not require such purging. Inspect the pilot flame (remove logs, if necessary, handling carefully). Millivolt Appliance Checkout The gas control system on these appliances is a millivolt standing pilot type. It consists of a pilot burner, a piezo ignitor, a gas control valve, a burner assembly and an ON/OFF wall switch. A temperature limit switch is wired in series with the millivolt wall switch and gas control valve. If a higher than normal temperature is sensed due to a blocked vent or prolonged downdraft, the limit switch will open and cause the burner to shut off. The pilot flame should be steady, not lifting or floating. Flame should be blue in color with traces of orange at the outer edge. The top ..." (9 mm) at the pilot generator (thermopile) should be engulfed in the pilot flame (Figure 30 ). ..." (10 mm) Figure 30 If the pilot flame pattern is not as shown in Figure 30, adjust it as follows: 1. Remove the pilot adjustment cap located on the main gas valve. 2.2. 3. Replace the pilot adjustment cap. Replace logs if removed for pilot inspection. To light the burner; rotate the gas valve control knob counterclockwise to the “ON” positionand then turn “ON” the remote wall switch. Electronic Appliance Checkout The gas control system on these appliances is an electronic low voltage gas control valve with an intermittent ignitor. It consists of a low voltage gas control valve, an intermittent ignition system, an electronic control module, transformer and a burner assembly. A temperature limit switch is wired in series with the gas control valve. If a higher than normal temperature is sensed, due to a blocked vent or prolonged downdraft, the limit switch will open and cause the burner to shut off. The pilot flame should be steady, not lifting or floating. Flame should be blue in color with traces of orange at the outer edge. To light the burner, push the gas control lever in and toward the left to the “ON” position. Turn ‘ON’ the remote wall switch. Ensure the ignitor lights the pilot. The pilot flame should engulf the ignitor. Ste...
