Installation

Main Piping connections

NOTE

Refer to warnings and cautions on page 2 before attempting installation. All piping must comply with local codes, ordinances, and/or national fuel gas codes.

1.Turn off electrical power to the system at the fuse 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.This valve may be installed upright, + or – 90˚ from upright, or vertical (refer to figure 1). The arrows on the valve iden- tification label and on the bottom plate indicate direction of gas flow through the valve

4.You should use new pipe that is properly chamfered, 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 (50ft lbs max).

7.See SYSTEMWIRING when making electrical connections. After all gas and electrical connections 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.

Pilot Gas Connection

Models 36H3X and 36H6X require a pilot

connection.

Loosen the pilot fitting until it is finger-tight.

Insert clean, deburred tubing all the way through the fitting. While holding the tubing securely, slowly tighten fitting until you feel a slight “give”. Tighten the fitting an additional 1 1/2 turns.
