INSTALLATION

Continued

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 toalljoints.Bubblesformingshow a leak. Correct all leaks at once.

CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and heater.SeeguidelinesunderCon- necting to Gas Supply, page 11.

3.

Pressurize supply piping system by either

 

opening propane/LP supply tank valve for

 

propane/LP gas or opening main gas valve

 

located 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 fit-

 

tings for leaks.

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

1.Close equipment shutoff valve (see Figure 15, page 16).

2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve located on or near gas meter for natural gas or using compressed air.
