DESCRIPTION
Operator: Save these instructions for future use!
Ideal for use on wall heaters, space heaters, consoles,
etc., this gas pilot safety valve provides 100% shut-off of
bothpilotandmainburnergassupplyintheeventofpilot
flamefailure.Thisvalveisequipped with a3-positiongas
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 thermo-
couple 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.
Never use flame to detect leaks.
Do not leave unused inlet unplugged.
DO NOT USE THESE GAS VALVES WITH
UNVENTED APPLICATIONS.
MAIN PIPING CONNECTIONS
1. Besurethemaingassupplyisshutoffbeforestarting
theinstallation.Thegasvalvemaybeinstalledinany
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. Ifthesideinletistobeused,itisnecessarytoremove
the plug and install it in the bottom inlet. This proce-
dure 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
approvedforallgases,onlytothemalethreadsofthe
plug. DO NOT apply compound to first two threads.
Do not overtighten the plug.
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.
Applyingpipe jointcompoundto pipethreadswill 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. Ifaviseoropen-endwrenchisusedtoholdthecontrol
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

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 1⁄4to 1⁄2additional turn using a small
wrench. Do not overtighten.

FOR YOUR SAFETY READ BEFORE LIGHTING
WARNING
!
If you do not follow these instructions exactly, a fire or explosion
may result causing property damage, personal injury or loss of life.
A. This appliance has a pilot which must be lighted by hand.
When lighting the pilot, follow these instructions exactly.
B. BEFORE LIGHTING smell all around the appliance area for
gas. Be sure to smell next to the floor because some gas is
heavier than air and will settle on the floor.
FOR YOUR SAFETY
“WHAT TO DO IF YOU SMELL GAS”
• Do not try to light any appliance.
• Do not touch any electrical switch; do not use any
phone in your building.
• Immediately call your gas supplier from a neighbor's
phone. Follow the gas supplier's instructions.
• If you cannot reach your gas supplier, call the fire
department.
C. Use only your hand to push in or turn the gas control knob.
Never use tools. If the knob will not push in or turn by hand,
don't try to repair it, call a qualified service technician. Force
or attempted repair may result in a fire or explosion.
D. Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and
any gas control which has been under water.
PILOT LIGHTING PROCEDURE
1. Turn the gas control knob to the OFF position (it will
be necessary to depress the knob slightly at the
PILOTposition). Allowfiveminutes foranygas inthe
combustion chamber to escape (LP gas, which is
heavier than air, may require forced ventilation).
2. Turn the gas control knob to the PILOT position.
3. Push down on the gas control knob and light the pilot
immediately. Hold the knob down for one full minute
after lighting the pilot.
4. Whenthegascontrolknobisreleased,thepilotflame
should continue to burn (if the pilot goes out, repeat
the above steps).
5. Rotate the gas control knob from PILOT to ON
position (full counterclockwise position) to
supply full flow to main burner.
NotturningthegascontrolknobtothefullON positionwill
reduce the flow and could result in poor ignition of main
burner.
PILOT FLAME ADJUSTMENT
These controls are factory preset and will not normally
require additional adjustment of the pilot flame. If field
adjustment of the pilot flame is required, remove the pilot
adjust cover screw to expose the adjusting screw. Turn
theadjustingscrewclockwise( ) toreduceflame,
or counterclockwise ( ) to increase flame. Re-
place pilot adjust cover screw and tighten securely.
