USE AND INSTALLATION INSTRUCTIONS
INSTALL PIPING TO GAS VALVE
All piping must comply with local codes and ordinances or with the National Fuel Gas code (ANSI
Z223.1 NFPA No. 54) whichever applies. Tubing installation must comply with approved standards
and practices. Use appropriately sized fittings when
connecting aluminum tubing to the pilot outlet.
1. Use new, clean and correctly reamed pipe free from
burrs, chips, debris and any foreign matter. When
tubing is used, make sure the ends are square
and clean. All tubing bends must be smooth and
without deformation.
2. Run pipe or tubing to the valve. If tubing is used,
obtain a tube-to-pipe coupling to connect the tubing to the valve.
3. Install sediment trap (Drip Leg) in the supply line to the gas valve.
INSTALLING THE VALVE
1. Mount the valve in the desired position (NEVER UPSIDE DOWN).
2. Mount the valve so the flow of gas is consistent with the gas flow arrows on the valve.
3. Apply a moderate amount of quality pipe compound (DO NOT USE TEFLON TAPE)
to the pipe only, leaving two end threads bare. On LP installations, use compound that
resists exposure to LP gas.
4. Remove seals over inlet and outlets if necessary.
5. Connect pipe to valve inlet and outlet. Place a 1” 1/16 wrench on valve as shown in Fig. 3.
6. Thread pipe into the valve until a gas tight seal is achieved. Typically, for NPT thread,
penetration is usually no more than the diameter of the pipe or 2 and 1/4 turns thread. Valve
distortion or mechanical failure can result if the pipe is inserted too deeply.
7. Connect pilot tubing to valve with appropriately sized fittings as shown in Fig. 4.
8. Confirm gas tight seals with gas leak test.
