Installation

Continued

IMPORTANT: Make sure the heater burners are level. If heater is not level, heater will not work properly. For thermostat models, avoid damage to thermostat bulb. Avoid nicks or sharp bends in thermostat bulb wire. Keep thermostat bulb in mounting bracket until ready to mount base to floor. See Optional Positioning Of Thermostat Sensing Bulb, page 32.

Installation Items Needed

• hardware package (provided with heater)

• approved flexible gas hose and fittings (not provided) (if allowed by local codes)

• sealant (resistant to propane/LP gas, not pro- vided)

• electric drill with 3/16” masonry drill bit Note: Install optional GHRCTB Receiver and Hand-Held Remote Control Kit (see Accessories, page 42) before installing gas log heater (Remote- Ready Models Only). See installation instructions included with the kit.

1.Apply pipe joint sealant lightly to male threads of gas fitting (not provided). For Thermostati- cally-Controlled Models connect approved flexible gas hose to gas regulator of heater (see Figure 11). For Remote-Ready models connect approved flexible gas hose to inlet side of gas control (see Figure 12). IMPOR- TANT: Hold gas regulator with wrench when connecting flexible gas hose (Thermostati- cally-Controlled Models Only).

2.Position heater base assembly in fireplace.

3.Mark screw locations through holes in front panel of base (see Figure 13). If installing in a brick-bottom fireplace, mark screw locations in mortar joint of bricks.

4.Remove heater base from fireplace.

5.Drill holes at marked locations using 3/16" drill bit.

6.Attach base, through holes in front panel of base, to fireplace floor using masonry screws provided in hardware package (see Figure 13).

7.Connect to gas supply. See Connecting To Gas Supply, page 14.
