INSTALLATION INSTRUCTIONS

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 and 36C10 series valves are designed to meet requirements for use on standing continuous pilot systems. 36C03 combination models include a pressure regulator, 100% shut-offauto- matic pilot, and main operator. 36C10 models do not have a pressure regulator.

MAIN PIPING CONNECTIONS

NOTE

Allpipingmustcomplywithlocalcodes,ordinances, and/or national fuel gas codes.

1.Turnoffelectricalpowertothesystematthefuse boxorcircuitbreaker.Alsoturnoffthemaingas 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 (see fig. 1). 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.

INSTALLATION

5.Applypipejointcompound(pipedope)orteflon tape that is approved for all gases, only to the male threads of the pipe joints. DO NOT apply compoundorteflontapetothefirsttwothreads (seefig.3 for typical piping connections).

6.Ifyouareusingaviseoropen-endwrenchtohold 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

Connect the leads from the E.C.O. terminals to the E.C.O. device on the furnace. Test the E.C.O. device for continuity. If there is no continuity, the powerunitwillnotholdin.Seefigure5.

If the furnace does not have an E.C.O. device, jumper the E.C.O. terminals on the valve with the jumper lead provided.

INSTALLATION

THERMOCOUPLE CONNECTION

(24 VAC AND 120 VACMODELS)

The thermocouple connection should be clean to ensure good electrical contact.

Run the thermocouple nut into the power unit tapping as far as possible by hand. Then use a small wrench to set the nut with a 1/4 to 1/2 ad-

ditional turn. Do not overtighten.

PILOT GENERATOR CONNECTION

(FOR .750 VACMODELS)

Be sure the pilot generator is completely engaged into the pilot burner.

Be sure that the two terminals from the pilot generator are securely tightened beneath the proper screws on the valve.

Connect the power unit lead to the high limit and the high limit to the TH-PG terminal.

PILOT GAS ADJUSTMENT

Ifthepilotflameislowanddoesnotengulfthe bulbofthemercuryflamesensor,thesystemwill not energize the main valve. If pilot gas pressure is too high, gas will sputter past the ignition electrode, and may not ignite. High pilot gas pressure mayalsocausetheflametoliftofftheburner, causingtheflamesensorbulbtosense“low”heat.

To adjust the pilot gas pressure, remove the cover screw(seefig.8). To REDUCE pilot pressure, turn the pilot adjust screw (beneath the cover screw) clockwise. To INCREASE pilot pressure, turn the pilot adjust screw counterclockwise. Replace and tighten cover screw.

ADJUSTMENT

The pressure regulator has been factory adjusted

(seecontrollabelforspecificsetting).Although additional adjustments will not normally be necessary, you may adjust the regulator. Do not force the adjusting screw beyond the limits that it can easily be adjusted.

1.Energize valve to ignite main burner.

2.Remove “Reg. Adj.” cover screw (see fig. 9).

3.To DECREASE outlet pressure, turn the adjusting screw (beneath the cover screw) counterclockwise. To INCREASE outlet pressure, turn the adjusting screw clockwise.

4.Replace the cover screw. Cycle the valve two or three times to verify regulator setting.
