INSTALLING HEATER ASSEMBLY

WARNING: If installing in a sunken fireplace, special care is needed. You must raise the fire- placefloortoallowaccesstoheater control panel. This will insure ade- quate air flow and guard against sooting. Raise fireplace floor with noncombustible material. Make sure material is secure.

CAUTION: Do not pick up heater assembly by logs. This could damage unit. Only handle assembly by grates.

IMPORTANT: Make sure the heater burner is level. If heater is not level, heater will not work properly.

Installation Items Needed

control cover kit (optional - see Accessories, page 27)

approved flexible gas hose and fittings (pro- vided with heater) (if allowed by local codes)

sealant (resistant to propane/LP gas, not provided)

Note: Install optional GHRCTB Receiver and Hand-Held Remote Control Kit (see Accessories, page 27) before installing gas log heater. See in- stallation instructions included with the kit.

1.Apply pipe joint sealant lightly to male threads of gas fitting (not provided). Connect approved flexible gas hose to inlet side of gas control (see Figure 12).

2.Position heater assembly in fireplace.

3.Connect to gas supply. See Connecting To Gas Supply.

CONNECTING TO GAS SUPPLY

WARNING: This appliance requires a 3/8" NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING:Aqualifiedservice personmustconnectheatertogas supply. Follow all local codes.

CAUTION: Never connect propane/LP fireplace directly to the propane/LP supply. This heater requires an external regu- lator (not supplied). Install the external regulator between the heater and propane/LP supply.

WARNING: Never connect natural gas fireplace to private (non-utility) gas wells. This gas is commonly known as wellhead gas.

Installation Items Needed Before installing heater, make sure you have the items listed below.

external regulator (supplied by installer for propane/LP models only)

piping (check local codes)

sealant (resistant to propane/LP gas)

equipment shutoff valve *

test gauge connection *

sediment trap

tee joint

pipe wrench

approved flexible gas line with gas connector (if allowed by local codes) (provided)

*A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 27.
