Field Wiring Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. Refer to Figure 10 for the wiring schematic for these fireplaces. This fireplace is completely wired internally. On the right hand side of the fireplace, at the rear, are four (4) wires required to connect the Battery and switch for operation. Two brown wires are for the connection of the switch. These are labeled SW and SW. A black and red pair are for connection to the battery pack. These are labeled (+) and (–). These wires are for low voltage current. An electrical box has been provided to contain both the switch and battery pack. Mount the box in an appropriate location within the length of the wiring provided. Feed all four wires through one of the lower inlets to the box. Connect the switch wires to the switch and the corresponding (+), (–) to the battery holder. Install two D-cell batteries (not provided) and test the switch before closing the switch box (refer to Figure 11 ). The igniter should spark to the pilot when the switch is on.

Figure 12 illustrates two methods for connecting the gas supply. The flex-line method is acceptable in the U.S., however, Canadian requirements vary depending on locality. Installation must be in compliance with local codes. These appliances are equipped with a gas flex line for use (where permitted) in connecting the unit to the gas line. A gas flex line is provided to aid in attaching the direct vent appliance to the gas supply. The gas flex line can only be used where local codes permit. See Figure 12 for flex line description. The flex line is rated for both natural and propane gas. A manual shut off valve is also provided with the flex line. The gas control valve is located under the refractory cover in front of the burner. To access the valve, lift out the center refractory and remove the access cover (see Figure 13 ). The control valves have a 3/8" (10 mm) NPT thread inlet port. Secure all joints tightly using appropriate tools and sealing compounds (ensure propane resistant compounds are used in propane applications). Turn on gas supply and test for gas leaks, using a gas leak test solution (also referred to as bubble leak solution). Note: Using a soapy water solution (50% dish soap, 50% water) is an effective leak test solution but it is not recommended, because the soap residue that is left on the pies/fittings can result in corrosion over time. Never use an open flame to check for leaks. A. Light the appliance (refer to the lighting instructions label in the control compartment or in the Homeowner's Care and Operation Instructions). B. Brush all joints and connections with the gas leak test solution to check for leaks. If bubbles are formed, or gas odor is detected, turn the gas control knob to the “OFF” position. Either tighten or refasten the leaking connection and retest as described above. C. When the gas lines are tested and leak free, be sure to rinse off the leak testing solution.

The pan can over heat and may warp and the fireplace may shut off automatically. Rear Log Installing the logs After verifying that the fireplace operates properly, replace the cover and set the bottom refractory components in place. Use two (2) bags of lava rock to fill the bottom of the burner tray to completely cover the burner tube. Level the rock evenly. Place the rear log approximately centered as shown in Figure 14. Place the base log approximately as shown in Figure 15. The remaining logs can be placed across the rear and base log approximately as shown in Figure 16. The exact position of these logs is not critical. Due to the natu...
