FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.

DESCRIPTION

The 36J22/24/54/55 combination gas valves are de-

 

 

 

 

signed for direct spark ignition (DSI) and hot surface

 

 

 

 

ignition (HSI) system applications. These valves

 

 

 

 

are equipped with redundant and main solenoid

 

 

 

 

valves that control gas flow to the main burners, a

valves. The 36J24 and 36J55 are also equipped

 

 

 

 

with a slow-opening pressure regulator for softer

 

 

 

 

lighting characteristics. When the second solenoid

PRECAUTIONS

DO NOT BEGIN INSTALLATION UNTIL YOU READ THE FOLLOWING PRECAUTIONS.

 

! WARNING

 

Ifyoudonotfollowtheseinstructionsexactly,afireorexplosion

1.Failuretoturnoffelectricormaingas supply to heating system could cause personal injury and/or property damage byshock,gassuffocation,fire,and/or explosion.

2.Do not use this control on circuits exceedingspecifiedvoltage.Higher voltage will damage the control and may causeshockorfirehazard.

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

propertydamage,gassuffocation,fire, and/or explosion may result.

5.Do not use a gas valve which appears to be damaged. A damaged valve may cause personal injury and/or property damage duetoshock,gassuffocation,fireand/or explosion. Contact supplier to replace any valve that appears to have been damaged.

6.Do not use a gas valve that has been in direct contact with water. Water entering gas valve may result in concealed internal damage to gas valve. Personal injury and/ orpropertydamage,gassuffocation,fire and/or explosion may result.

!WARNING

Properly install gas piping to control.

!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.).

3.Cleangaspipingofcontaminants,cuttingfluid,orotherchemicalswhichmightreactharmfully with the gas valve components before install.

MAIN PIPING CONNECTIONS

NOTE

Refer to warnings and cautions on page 2 before attempting installation. All piping must comply with local codes, ordinances, and/or national fuel gas codes.

1.Turnoffelectricalpowertothesystematthe fuseboxorcircuitbreaker.Alsoturnoffthe main gas supply.

2. Ifreplacinganexistingvalve,disconnectall plumbing and electrical connections from the old control.

3.The control may be installed in any position. The arrow on the bottom plate indicates the directionofinletgasflow.

4.You should use new pipe that is properly chamfered,reamed,andfreeofburrsand chips.Ifyouareusingoldpipe,besureitis cleanandfreeofrust,scale,burrs,chips,and old pipe joint compound.

5.Apply pipe joint compound (pipe dope) that is approved for all gases, only to the male threads of the pipe joints. DO NOT apply compoundtothefirsttwothreads(seefigure

2 for typical piping connections).

6.If you are using a vise or open-end wrench to holdthevalvewhileinstallingpiping,donot tightenexcessively,asthismaydamagethe valve. (Torque: 375 in-lb maximum.) Do not cross-thread during installation as this may damage the valve.

7.See SYSTEM WIRING when making electrical connections. After all gas and electrical connectionsarecompleted,turngasonandcheck for gas leaks with leak detection solution or soap suds. Bubbles forming indicate a leak.

SHUT OFF GAS AND FIX ALL LEAKS IMMEDIATELY.

LP GAS CONVERSION

ForLPgasconversion,usetheLPconversionkit supplied with this control. Refer to the instructions packed with LP conversion kit.

NOTE

All piping must comply with local codes, ordinances, and/or national fuel gas codes.

NOTE: A MANUAL SHUTOFF VALVE MUST BE INSTALLED WITHIN 6 FEET OF THE EQUIPMENT

ADJUSTMENT

PRESSURE REGULATOR

ADJUSTMENT

These controls are shipped from the factory set forNaturalGaswiththeregulatorsetasspecified on the control label. Consult the appliance rating plate to ensure burner manifold pressure is as specified.Ifanotheroutletpressureisrequired, followthesesteps.ForLPgasconversion,useLP conversion kit.

NOTE

NATURAL GAS

Single Stage Models – Outlet pressure will be factory-adjusted in the 2.5" to 5" range. The valve cannot be adjusted outside this range.

Two-Stage Models: Low outlet pressure will be factoryadjusted in the 1 to 4" W.C. range and high outlet pressure will also be factory-adjusted in the 2 to 5" W.C. range.

The valve cannot be adjusted outside this range and the high outlet pressure setting must always be set at least 1" above the low outlet pressure setting.

OUTLET PRESSURE ADJUSTMENT

1.Turnoffallelectricalpowertothesystem.

2.Backoutletpressuretestscrewoutoneturn, counterclockwise,notmorethanoneturn. (seefig.8)

3.Attach a hose and manometer to the outlet pressure boss of the valve.

4.Turn on system power. Set thermostat to call for heat (low stage for two-stage systems). Main burner should light. Proceed to step 7 for single stage systems.

5.(2-stage only) Remove regulator cover screw from the low outlet pressure regulator adjust tower(fig.8) and turn screw clockwise

( )toincreasepressure,orcounterclockwise ( ) to decrease pressure. Always adjust regulator according to original equipmentmanufacturer'sspecificationslistedon the appliance rating plate. Replace regulator cover screw.

6.(2-stage only) Set thermostat to call for high stage.

7.Remove regulator cover screw from the single stage or high outlet pressure regulator adjust tower(fig.8) and turn screw clockwise

( )toincreasepressure,orcounterclockwise ( ) to decrease pressure. Always adjust regulator according to original equipmentmanufacturer'sspecificationslistedon the appliance rating plate. Replace regulator cover screw.

8.Turnoffallelectricalpowertothesystem.

9.Remove manometer hose and turn outlet pressure test screw in to seal pressure port (clockwise,7 in-lb minimum).

10.Turn on electrical power to the system.

11. Turn on system power and energize valve.

12.Usingaleakdetectionsolutionorsoapsuds, check for leaks at pressure boss screw. Bubbles forming indicate a leak. SHUT OFF GAS AND FIX ALL LEAKS IMMEDIATELY.
