Features at a Glance

Key components: Main gas valve body, pressure regulator, solenoid coils, manual shut-off, pressure taps, and wiring terminals.

Feature	Description
Manual shut-off	Allows manual gas flow control during service
Pressure regulator	Maintains consistent gas pressure to burner
Solenoid coils	Electrically operated valves for gas control
Pressure taps	For pressure testing and adjustment
Wiring terminals	For thermostat and control system connection
Gas inlet/outlet	Standard pipe thread connections
Safety lockout	Prevents gas flow during unsafe conditions
Pilot adjustment	For pilot flame regulation
Status indicator	Visual indicators for valve position
Mounting bracket	For secure installation

Installation

Unpack and inspect contents. Ensure proper gas type compatibility.

Shut off gas supply: Turn off main gas valve and electrical power.
Remove old valve: Disconnect wiring and piping from existing valve.
Install new valve: Apply pipe sealant to threads, connect gas lines.
Connect wiring: Follow wiring diagram for proper connections.
Test for leaks: Use leak detection solution on all connections.

WARNING! Gas valves must be installed by qualified technicians only. Failure to properly install can cause gas leaks, fire, or explosion.

Operation

Gas valve operates automatically based on thermostat signals.

Normal operation: Thermostat calls for heat, valve opens to allow gas flow.
Pilot operation: For standing pilot models, pilot remains lit continuously.
Safety shutdown: Valve closes if flame sensor detects no flame.
Pressure regulation: Maintains consistent pressure to burner assembly.
Manual override: Use manual shut-off for emergency closure.

CAUTION! Never bypass safety controls. Regular inspection required for safe operation.

Specifications

Controls and Settings

Access pressure adjustment via pressure tap ports. Manual shut-off for service.

Adjustments: Pressure regulator adjustment screw, pilot adjustment screw, manual shut-off lever.

Pressure Regulation: Adjust outlet pressure using manometer and adjustment screw. Pilot Adjustment: Regulate pilot flame height for optimal operation. Manual Operation: Use shut-off lever for emergency closure. Electrical Testing: Check coil resistance and voltage at terminals.

Connecting to System

Gas connections: Inlet from gas supply, outlet to burner manifold. Electrical: Thermostat and control board connections.

Turn off gas and electrical power before connecting.
Connect gas piping using proper pipe sealant.
Wire according to furnace control board diagram.
Verify all connections are tight and secure.

Tip: Use two wrenches when connecting piping to prevent damage to valve body.

Maintenance Procedures

Regular maintenance ensures safe and efficient operation.

Annual inspection: Check for gas leaks and proper operation.
Pressure testing: Verify inlet and outlet pressures are within specifications.
Electrical testing: Check coil resistance and voltage.
Cleaning: Keep valve area free of dust and debris.
Lubrication: Some models require periodic lubrication of moving parts.

WARNING! Maintenance must be performed by qualified technicians. Never attempt repairs without proper training.

Safety Features

Automatic shut-off: Closes if no flame detected. Pressure relief: Prevents over-pressure conditions. Thermal protection: Shuts off if overheating detected. Manual override: Emergency manual shut-off capability.

Care & Cleaning

Turn off gas and electrical power before cleaning. Use dry cloth only; no liquids or chemicals.

CAUTION! Do not use compressed air for cleaning as it can damage internal components. Keep area around valve clear of combustible materials.

Regulatory Information

UL listed: Meets Underwriters Laboratories standards. ANSI compliant: Conforms to American National Standards Institute requirements. CSA certified: Canadian Standards Association approved.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No gas flow	Power issue/valve closed	Check 24V power to coil; verify manual valve open; check thermostat.
Insufficient gas pressure	Regulator issue	Adjust pressure regulator; check inlet pressure; clean filter.
Valve not opening	Faulty coil/control issue	Test coil resistance; check control board signals; replace if faulty.
Gas leak detected	Loose connections	Tighten all connections; replace damaged components; retest.
Intermittent operation	Wiring issues	Check all electrical connections; test voltage stability; inspect wiring.

Reset: Turn power off for 30 seconds then restore if lockout occurs.
