INSTALLATION

INSTALLATION

These gas valves should be installed according to the following instructions. Check for gas leaks with a soap solution after completing installation.

!CAUTION

Never use flame to detect leaks.

!CAUTION

Do not leave unused inlet unplugged.

!CAUTION

DO NOT USE THESE GAS VALVES WITH UNVENTED APPLICATIONS.

5.Apply pipe joint compound (pipe dope) that is ap- proved for all gases, only to the male threads of pipe joints. DO NOT apply compound to first two threads. Do not thread pipe too far.

NOTE

Applying pipe joint compound to pipe threads will prevent chips from passing onto internal valve parts, since the pipe joint compound will collect and retain chips that are formed as the pipe is threaded into the body.

6.If a vise or open-end wrench is used to hold the control while installing piping, do not tighten excessively, as this may damage the control.

MAIN PIPING CONNECTIONS

PILOT GAS CONNECTION

1.Be sure the main gas supply is shut off before starting the installation. The gas valve may be installed in any position, but it should be located so that the gas control knob is easily accessible.

2.Direction of gas flow is indicated by the directional arrow on the outlet boss.

3.You should use new pipe, which has been properly chamfered and reamed. If you use old pipe, be sure it is clean and free of rust, scale, burrs, chips and old pipe joint compound.

4.If the side inlet is to be used, it is necessary to remove the plug and install it in the bottom inlet. This proce- dure requires a 516” Allen wrench. Be sure the end of the plug is free of burrs, chips, etc. Before installing plug, apply pipe joint compound (pipe dope) that is approved for all gases, only to the male threads of the plug. DO NOT apply compound to first two threads. Do not overtighten the plug.

Install the fitting into the pilot gas tapping, turning until finger-tight. Insert clean, deburred tubing all the way through the fitting. Holding the tubing securely, slowly tighten the fitting until a slight “give” is felt. Then tighten an additional 112 turns.

THERMOCOUPLE

The thermocouple connector should be clean for good electrical contact. Run the thermocouple nut into the thermocouple connection as far as possible by hand. Then set the nut with 14 to 12 additional turn using a small wrench. Do not overtighten.
