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 3­position 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

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.

!

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.

If you do not follow these instructions exactly, a fire or explosion may
result, causing property damage, personal injury or loss of life.

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.

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 com-

pound 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.

PILOT GAS CONNECTION

Install fitting into pilot gas outlet (see fig. 2), turning until
finger-tight. Insert clean, deburred tubing all the way
through the fitting. While holding the tubing securely,
slowly tighten fitting until you feel a slight "give". Tighten
the fitting an additional 1 1/2 turns.

NOTE

All wiring should be installed in accordance with local
and national electrical codes and ordinances.

Always check that the electrical power supply used agrees
with the voltage and frequency shown on the gas control.

The typical wiring diagram shows only the terminal iden­tification and wiring hook up. Always refer to wiring
instructions provided by Equipment Manufacturer for sys­tem hookup operation.
