INSTALLATION

Continued

Install sediment trap in supply line as shown in

Figure 13. 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: Hold the pressure regulator with

wrench when connecting it to gas piping and/or

fittings. Do not over tighten pipe connection to

regulator. The regulator body could be damaged.

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:Neveruseanopen flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. Bubbles form- ing show a leak. Correct all leaks at once.

gas, make sure external regula- tor has been installed between propane/LP supply and heater. See guidelines under Connect- ing to Gas Supply, page 10.

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 system. Pressures in excess of 1/2 psig (3.5 kPa) 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 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 a noncorrosive leak detection fluid to all 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.
