INSTALLATION

Main Piping connections

NOTE

Refer to warnings and cautions on page 3 before attempting installation. All piping must comply with local codes, ordinances, and/or national fuel gas codes.

1.Turnoffelectricalpowertothesystematthefuse box or circuit breaker. Also turn off the main gas supply.

2.If replacing an existing valve, disconnect all plumbing and electrical connections from the old control.

3.Thisvalvemaybeinstalledupright,+or–90˚from upright, or vertical (refer to fig. 1).The arrows on the valve identification label and on the bottom plate indicate direction of gas flow through the valve.

4.You should use new pipe that is properly cham- fered, reamed, and free of burrs and chips. If you are using old pipe, be sure it is clean and free of rust, scale, burrs, chips, and old pipe joint compound.

5.Apply pipe joint compound (pipe dope) or teflon tape that is approved for all gases, only to the male threads of the pipe joints. DO NOT apply compound or teflon tape to the first two threads (see fig. 3 for typical piping connections).

6.Do not tighten piping excessively, as this may damage the valve (50 ft lbs max).

7.See SYSTEM WIRING when making electrical connections. After all gas and electrical connec- tions are completed, turn gas on and check for gas leaks with leak detection solution or soap suds. Bubbles forming indicate a leak. SHUT

OFF GAS AND FIX ALL LEAKS IMMEDIATELY.

LP GAS CONVERSION

For LP gas conversion, use the LP conversion kit supplied with this control. Refer to the instruc- tions packed with LP conversion kit.

Pilot Gas Connection

These gas valves are shipped with the pilot outlet plugged. For installations requiring pilot gas (Proven/Intermittent Pilot Systems), remove the plug from the pilot gas outlet (see fig. 2) and use the fitting packed separately with the valve.

Install the fitting into the pilot gas outlet, turning until finger tight. Insert clean, de-burred 1/4" O.D. tubing all the way through the fitting. While hold- ing the tubing securely, slowly tighten the fitting until you feel a slight “give”. Tighten the fitting an additional 1-1/2turns.

The plug should not be removed for a Direct Burner Ignition system such as Direct Spark or Hot Surface Ignition.

Refer to page 7 for pilot flame adjustment infor- mation.

NOTE

All piping must comply with local codes, ordinances, and/or national fuel gas codes.

NOTE: A MANUAL SHUTOFF VALVE MUST BE INSTALLED WITHIN 6 FEET OF THE EQUIPMENT
