INFRARED NATURAL GAS HEATER
INSTALLATION
Continued
CONNECTING TO GAS SUPPLY
NOTICE: A qualified service per- son must connect heater to gas supply. Follow all local codes.
Install sediment trap in supply line as shown in Figure 13. Locate sediment trap where it is within reach for cleaning. 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 pip- ing and/or fittings.
WARNING: Never connect heater to private
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, heater regulator damage could occur.
CAUTION: Use only new, black iron or steel pipe. Inter-

Installation must include a manual 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 13).
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.
