Important Safety Information

WARNING: EXPLOSION HAZARD. Severe injury or death can result.

• Installation and servicing of heating equipment must be performed by a qualified installer or service agency.
• Failure to follow these instructions exactly can result in fire or explosion, causing property damage, personal injury, or loss of life.
• Do not use this valve if any part has been submerged in water. A qualified service technician should inspect the appliance and replace any part of the control system and any gas control that has been submerged in water.
• Always turn off the main gas supply to the appliance before attempting any installation, maintenance, or servicing.
• Check for gas leaks after installation or servicing.

Key Features

• Includes a manual valve, two automatic operators, a servo pressure regulator, and a pilot adjustment.
• Provides two automatic valves for enhanced control.
• The solenoid-operated first automatic valve opens upon a thermostat call for heat and closes when the call for heat ends.
• The diaphragm-operated second automatic valve opens under the control of the regulator and closes if the gas or power supply is interrupted.
• All adjustments, wiring connections, and the pilot outlet are conveniently accessible from the top of the control unit.

Installation Instructions

Professional installation by a qualified technician is strongly recommended. Incorrect installation can lead to hazardous conditions.

1. Turn Off Power and Gas: Before beginning any work, ensure the main electrical power and gas supply to the appliance are completely shut off.
2. Remove Old Valve: Carefully disconnect all wiring and gas piping from the existing gas valve. Note the orientation and connections for proper reinstallation.
3. Prepare New Valve: Apply appropriate pipe sealant to the threaded connections of the new Honeywell VR8200A2116 valve. Ensure the sealant is compatible with natural gas or LP gas, as applicable.
4. Install New Valve: Mount the new gas valve in the same position and orientation as the old one. Connect the gas piping securely, ensuring no leaks.
5. Wire Connections: Connect all electrical wiring to the appropriate terminals on the new valve. Refer to the appliance manufacturer's wiring diagram for correct connections.
6. Check for Leaks: After installation, turn on the gas supply and check all connections for leaks using a soap solution. Never use an open flame to check for leaks.
7. Restore Power: Once all connections are secure and leak-free, restore electrical power to the appliance.
8. Pilot Adjustment: If necessary, adjust the pilot flame according to the appliance manufacturer's instructions using the pilot adjustment screw on the valve.

Operation

The Honeywell VR8200A2116 gas valve operates automatically in conjunction with your appliance's thermostat and control system.

• When the thermostat calls for heat, the first automatic valve opens, allowing gas to flow to the pilot and then to the main burner.
• The second automatic valve, controlled by the regulator, ensures proper gas pressure and flow to the main burner.
• If the thermostat satisfies the heat demand, or if there is an interruption in gas or power supply, both automatic valves will close, shutting off the gas flow.
• The manual valve allows for complete shut-off of gas to the appliance for servicing.

Maintenance

The Honeywell VR8200A2116 gas valve is designed for reliable operation with minimal maintenance. However, periodic inspection by a qualified service technician is recommended as part of routine appliance maintenance.

• Annual Inspection: Have a qualified technician inspect the gas valve and associated components annually for proper operation, signs of wear, or potential leaks.
• Cleaning: Keep the exterior of the valve clean and free from dust or debris. Do not use harsh chemicals or abrasive cleaners.
• Pilot Flame Check: Ensure the pilot flame is stable and properly sized according to the appliance manufacturer's specifications.

Troubleshooting

If your appliance is not operating correctly, consult the appliance manufacturer's troubleshooting guide first. For issues related to the gas valve, consider the following:

• No Gas Flow:
  • Check if the manual valve on the gas control is in the "ON" position.
  • Ensure the main gas supply to the appliance is open.
  • Verify that electrical power is supplied to the gas valve.
  • Confirm the thermostat is calling for heat.
• Pilot Light Not Lighting:
  • Check for obstructions in the pilot tubing or orifice.
  • Ensure adequate gas pressure.
  • Verify the igniter or thermocouple is functioning correctly.
• Main Burner Not Lighting:
  • Ensure the pilot light is lit and stable.
  • Check for proper electrical signal from the thermostat to the gas valve.
  • Verify the gas pressure regulator setting.

Note: For complex issues or if you are unsure, contact a qualified HVAC service technician.
