MANTEL CLEARANCES FOR BUILT-IN INSTALLATION

If placing mantel above built-in fireplace, you must meet minimum clearance between mantel shelf and top of fireplace opening.

If your installation does not meet the above minimum clearances, you must:

• raise the mantel to an acceptable height,

OR

• remove the mantel.

INSTALLING GAS PIPING TO FIREPLACE LOCATION

WARNING: This appliance re- quires a 1/2" NPT (National Pipe Thread) inlet connection to the pressure regulator.

WARNING: A qualified ser- vice person must connect fire- place to gas supply. Follow all local codes.

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

Installation Items Needed

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

•external regulator (supplied by installer)

•piping (check local codes)

•sealant (resistant to propane/LP gas)

•equipment shutoff valve *

•test gauge connection *

•sediment trap

•tee joint

•pipe wrench

*An CSA/AGA design-certified equipment shutoff valve with 1/8" NPT tap is an accept- able alternative to test gauge connection. Purchase the optional CSA/AGA design- certified equipment shutoff valve from your dealer. See Accessories, pages 22 and 23.

The installer must supply an external regu- lator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incom- ing gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure

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

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" diameter or greater to allow proper gas volume to fireplace. If pipe is too small, undue loss of pressure will occur.

Installation must include a 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 18).

IMPORTANT: Install equipment shutoff valve in an accessible location. The equip- ment shutoff 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 threads. This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged fireplace valves. Do not use sealant on flare threads.

CAUTION: Use pipe joint seal- ant that is resistant to liquid pe- troleum (LP) gas.
