CHECK GAS TYPE

Use only natural gas. If your gas supply is not natural gas, you must install ON/OFF Safety Valve/Pilot Kit (see Accessories, page 19). Call dealer where you bought your log set.

If the fireplace does not have a gas supply shutoff valve, one must be installed.

VENTING SPECIFICATIONS FOR INSTALLATION

Fireplace chimney flue and vent must be drafting properly. To check vent for proper drafting: Light a tightly rolled newspaper on one end and place at inside front edge of fireplace. Observe smoke and be sure vent is properly drawing it up the chimney. If smoke spills out into room, extinguish flame and remove any obstruction until proper venting is achieved.

Chimney flue damper must be fixed open to provide a minimum of 64 sq. in. of free air opening during operation of this log set. A multipurpose damper clamp is provided to fix the damper in position.

INSTALLING DAMPER CLAMP

Secure damper stop clamp provided to leading edge of damper as shown in Figure 3. If for any reason this clamp doesn't work on your fireplace, another suitable clamp or permanent stop must be installed, or damper blade must be cut or removed.

CONNECTING TO GAS SUPPLY

WARNING: A qualified service person must connect log set to gas supply. Follow all local codes.

Installation Items Needed

Before installing log set, make sure you have the items listed below.

piping (check local codes)

sealant (resistant to propane/LP gas)

equipment shutoff valve

test gauge connection

adjustable (crescent) wrench or pliers

sediment trap

tee joint

pipe wrench

WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

We recommend that you install a sediment trap in the supply line as shown in Figure 4. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sediment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into log set controls. If sediment trap is not installed or is installed wrong, log set may not run properly.

Approved Flexible Gas Hose (if allowed by local codes)

CAUTION: Use only new, black iron or steel pipe. Inter- nally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2"diameterorgreatertoallow proper gas volume to log set. If pipe is too small, undue loss of volume will occur.

Installation must include an equipment shutoff valve, union, and a plugged 1/8" NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from log set (see Figure 4).

IMPORTANT: Install equipment shutoff valve in an accessible location. The equipment shutoff valve is for turning on or shutting off gas to appliance.

Apply pipe joint sealant lightly to male NPT threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in a clogged burner injector.
