FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
Ideal for use on wall heaters, space heaters, consoles, etc., this gas pilot safety valve provides 100% shut-off of both pilot and main burner gas supply in the event of pilot flame failure. This valve is equipped with a 3-position gas control knob to provide for pilot lighting. This control also allows pilot flame adjustment.
If the pilot flame goes out during normal operation, or if there is insufficient pilot flame to provide proper thermo­couple output, the safety valve will close, stopping the flow of all gas. This valve is designed for use on all domestic heating gases up to 1⁄2” PSI.

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.

DO NOT USE THESE GAS VALVES WITH UNVENTED APPLICATIONS.
MAIN PIPING CONNECTIONS
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 proce­dure requires a 5⁄16” 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.
5. Apply pipe joint compound (pipe dope) that is ap­proved 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.
PILOT GAS CONNECTION
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 11⁄2 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 1⁄4 to 1⁄2 additional turn using a small wrench. Do not overtighten.
