VERIFYING APPLIANCE OPERATION With gas line installed, run initial system checkout before closing up the front of the unit. Follow the pilot lighting instructions provided in the Care and Operation Instructions. For piezo igniter location on millivolt appliances, (see Figure 19). Note: Lighting Instructions are also found on theliterature tag tied to the gas piping next to the gasvalve. To access the tag, open the lower control compartment door (see Figure 19). To open thecontrol compartment access panel, actuate the springloaded magnetic catches securing the panel. First, gently depress the upper right top corner of the paneluntil the magnet catch "pops" the door free. Then, gently pulling the panel forward, disengage the leftmagnet catch and allow the panel to swing down to open. 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 lighting of the appliance will not require such purging. Inspect the pilot fl ame (remove logs, if necessary, handling carefully). MILLIVOLT APPLIANCE CHECKOUT The pilot fl ame should be steady, not lifting or fl oating. Flame should be blue in color with traces of orange at the outer edge. The top 3/8 in. (10 mm) at the pilot generator (thermopile) and the top 1/8 in. minimum (tip) of the quick drop out thermocouple should be engulfed in the pilot fl ame. The fl ame should project 1 in. (25 mm) beyond the hood at all three ports (see Figure 22). Replace logs if removed for pilot inspection. To light the burner; turn “ON” the remote wall switch and rotate the gas valve control knob counterclockwise to the “ON” position (“ON” will be at the top side of the valve). ELECTRONIC APPLIANCE CHECKOUT To light the burner, turn ‘ON’ the wall or remote control switch. Ensure the igniter lights the pilot. The pilot fl ame should engulf the fl ame rod as shown in Figure 23. Thermocouple Hood Igniter Rod Thermopile Pilot Nozzels 3/8 in.

INSTALLING VOLCANIC STONE, GLOWING EMBERS, AND LOGS Locate the packaged carton of logs (which were located in the fi rebox). The decorative volcanic stone and glowing embers were packaged separately in plastic bags located in the control area of the fi replace. DO NOT attempt to install the logs until the appliance installation has been completed, the gas line connected and tested for leaks, and the initial burner operation has been checked out. Proper log placement is critical to encourage outstanding fl ame appearance and prevent sooting. When positioned properly as shown, logs will be positioned between fl ame peaks and will not impinge any fl ames. Refer to Figure ...
