INSTALLING GAS PIPING TO FIREPLACE (Cont.) CONNECTING FIREPLACE TO GAS SUPPLY

Installation Items Needed

Before installing fireplace, make sure you have the items listed below:

•external regulator (when Propane/LP gas is supplied)

•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)

*ACSAdesign-certified equipment shutoff valve with 1/8” NPTtap is an acceptable alternative to test gauge connection. Purchase the CSA design-certified equipment shutoff valve fromyour retailer.

For propane/LP connection only, the installer must supply an external regulator. You must reduce incoming gas pressure to between 11 and 14 inches of water column. If you do not reduce incoming gas pressure, fireplace regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 22, page 11.

Pointing the vent down protects it from freezing rain or sleet.

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in cer- tain areas. Check your local codes. Use pipe of 1/2” inside diameter or greater to allow proper gas volume to fireplace. If pipe is too small, undue loss of volume will occur.

Installation must include an equipment shutoff valve, union and plugged 1/8” NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from fireplace (see Figure 23).

IMPORTANT: Install main gas valve (equipment shutoff valve) in an accessible lcation. The main gas valve is for turning on or shutting off the gas to the appliance.

Check your building codes for any special requirements for locating equipment shutoff valve to fireplaces.

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 clogged fireplace valves.

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

Installation Items Needed

•3/4” and a 7/8” open end wrench or adjustable wrench

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

1.Remove lower louver door panel by lifting up unit disengaged and swing forward and out of the locating slots at the bottom.

2.Route flexible gas line (provided by installer) from equipment shutoff valve to fireplace.Route flexible gas supply line through one of the access holes on each side of the fireplace cabinet.

3.Attach flexible gas line from gas supply to the 1/2” flare fitting provided on the control valve (see Figure 24).

4.Check all gas connections for leaks. See Checking Gas Con- nections, page 13.
