Gas Supply Piping Connection

NOTICE

The gas supply piping must be installed in accordance to all applicable local, state and national codes and utility requirements.

1.Remove the burner jacket hood. Refer to Fig. 15 to pipe gas supply to the burner.

a.Install a pipe union at the factory sup- plied gas nipple, for ease of service.

b.Install a manual shutoff valve in the gas supply piping as shown in Fig. 15. For installations in Canada the installer must tag and identify the main shutoff valve.

c.Install a drip leg on the gas supply line prior to connecting to the ELITE gas train as shown in Fig. 15.

2.Support the gas piping using hangers. Do not support the piping by the unit or its components.

3.Purge all air from the gas supply piping.

4.Before placing the ELITE into operation, check and test all connections for leaks.

Close the manual shutoff valve during any pressure test with less than 13”w.c..

Disconnect the ELITE and its gas valve from the gas supply piping during any pressure test greater than 13”w.c..

WARNING

Do not check for gas leaks with an open flame. Use a gas detection device or bub- ble test. Failure to check for gas leaks can cause severe personal injury, death or substantial property damage.

5.Use pipe dope compatible with natural and propane gases. Apply sparingly only to the male threads of pipe joints so that pipe dope does not block gas flow.

WARNING

Failure to apply pipe dope as detailed above can result in severe personal injury, death or substantial property damage.

WARNING

Use a two-wrench method of tightening gas piping near the unit and its gas valve. Use one wrench to prevent the gas valve line connection from turning and the sec- ond to tighten adjacent piping. Failure to support the gas valve connection pip- ing could damage the valve and the gas line components.
