INSTALLATION

Continued

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 heater valves.

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

We recommend that you install a sediment trap in supply line as shown in Figure 14. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. 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.

CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting it to gas piping and/or fittings.

CHECKING GAS CONNECTIONS

WARNING: Test all gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.

WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.

CAUTION: Make sure external regulator has been installed between propane/LP supply and heater. See guidelines under Connecting to Gas Supply, page 11.

Pressure Testing Gas Supply Piping system

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas supply piping sys- tem. Pressures in excess of 1/2 psig will damage heater regulator.

2.Cap off open end of gas pipe where equipment shutoff valve was connected.

3.Pressurize supply piping system by either opening propane/LP sup- ply tank valve for propane/LP gas or opening main gas valve lo- cated on or near gas meter for natural gas, or using compressed air.

4.Check all joints of gas supply piping system. Apply noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Reconnect heater and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.

Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)

1.Close equipment shutoff valve (see Figure 15).

2.Pressurize supply piping system by either opening propane/LP sup- ply tank valve for propane/LP gas or opening main gas valve lo- cated on or near gas meter for natural gas, or using compressed air.

3.Check all joints from propane/LP supply tank to equipment shutoff valve for propane/LP gas (see Figure 16, page 13) or from gas meter to equipment shutoff valve for natural gas (see Figure 17, page 13). Apply noncorrosive leak de- tection fluid to gas joints. Bubbles forming show a leak.

4.Correct all leaks at once.
