(24 Volt, 120 Volt and .750 Volt Models)
INSTALLATION INSTRUCTIONS
Operator: Save these instructions for future use!
FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY
AND/OR PROPERTY DAMAGE.
DESCRIPTION
The 36C03, 36C13 and 36D34 complete gas controls combine into a single compact package the functions of 3- position gas cock, pressure regulator, 100% shut-off automatic pilot, and main operator. Separate models are available for use on 24 VAC, 120 VAC and .750 VDC systems. These controls can be mounted in any orientation except upside down.

SPECIFICATIONS
DO NOT BEGIN INSTALLATION UNTIL YOU READ THE FOLLOWING PRECAUTIONS.
! WARNING
If you do not follow these instructions exactly, a fire or explosion may result, causing property damage, personal injury or loss of life.
1.Failure to turn off electric or main gas supply to heating system could cause personal injury and/or property damage by shock, gas suffocation, fire, and/or explosion.
2.Do not use this control on circuits exceeding specified voltage. Higher voltage will damage the control and may cause shock or fire hazard.
3.NEVER USE FLAME OR ANY KIND OF SPARK TO CHECK FOR GAS LEAKS–COULD CAUSE FIRE AND/OR EXPLOSION.
4.Do not use a control set for natural gas with LP gas, or a control set for LP gas with natural gas. Personal injury and/or property damage, gas suffocation, fire, and/or explosion may result.
! CAUTION
1.Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring can cause equipment damage, property damage, and/or personal injury.
2.This control is not intended for use in locations where it may come in direct contact with water. Suitable protection must be provided to shield the control from exposure to water (dripping, spraying, rain, etc.).
INSTALLATION
MAIN PIPING CONNECTIONS
NOTE
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.The control may be installed in any orientation except upside down. The arrow on the valve indicates the direction of gas flow through the control.
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. 1 for typical piping connections).
6.If you are using a vise or open-end wrench to hold the valve while installing piping, do not tighten excessively, as this may damage the valve.
7.If additional clearance for the gas cock knob is required when installing the new valve in an existing system, rotate the knob to the position between ON and OFF. Depress the knob while turning the valve. The knob will depress only while in this position.
8.See SYSTEM WIRING 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.
