INSTALLING HEATER

Continued

Installation must include a manual shutoff valve, ground joint union, plugged 1/8" NPT tap, and a sediment trap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 7).

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 sealant that is resistant to liquid petro- leum (LP) gas.

Install sediment trap in supply line as shown in Figure 7. Locate sediment trap where it is within reach for cleaning. Locate sediment 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: Use two pipe wrenches when connecting gas piping to gas control valve of heater. This will prevent turning or damaging control valve.
