OPTIONAL MANTEL

See Instructions Included

With Mantel Kit.

Assembling Mantel

IMPORTANT: Only use the optional man- tels specified in this manual. See Accesso- ries, page 23 for proper mantel kits. This heater is only approved for use with models GMF800/GMU801 series, GM900F/ GM901U series, GM902F/GM903U series, GM700F/GM701U series, and GM702F/ GM703U series mantel kits. Using any other mantel will void the CSA/AGA approval for this heater. Only use models GMF800/ GMU801 series, GM900F/GM901U series, GM902F/GM903U series, GM700F/ GM701U series, and GM702F/GM703U series mantels with this heater. Do not use these mantels with any other product.

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" or greater diameter to allow proper gas volume to heater. If pipe is too small, undue loss of pressure 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 heater (see Figure 20).

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

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 heater valves.

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

We recommend that you install a sediment trap in supply line as shown in Figure 20. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sedi- ment trap where trapped matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed or is installed wrong, heater may not run properly.

IMPORTANT: Hold pressure regulator with wrench when connecting it to gas piping and/or fittings.

CONNECTING TO GAS SUPPLY

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

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

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

IMPORTANT: Check gas line pressure be- fore connecting heater to gas line. Gas line pressure must be no greater than 14 inches of water. If gas line pressure is higher,
