2. Safety Information
WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause property damage, injury, or death. Read the installation, operating, and maintenance instructions thoroughly before installing or servicing this equipment.
- Always shut off the main gas supply before installing or servicing the gas valve.
- Ensure all electrical connections are disconnected before working on the unit.
- Verify that the gas type (Natural Gas or LP) matches the valve's configuration. An LP conversion kit is included for flexibility.
- All work should be performed by a qualified technician in accordance with local codes and regulations.
- Check for gas leaks using a soap solution after installation; never use an open flame.
3. Setup & Installation
The White-Rodgers 36C03-333 gas valve is designed for standing pilot ignition systems. Follow these general steps for installation:
- Preparation: Turn off the main gas supply and electrical power to the appliance. Allow the appliance to cool.
- Remove Old Valve: Disconnect all gas piping and electrical wiring from the existing gas valve. Carefully remove the old valve.
- Install New Valve: Apply appropriate pipe sealant to all threaded connections. Install the new White-Rodgers 36C03-333 valve, ensuring correct orientation. The valve features a 1/2 inch inlet and a 3/4 inch outlet. A reducer bushing kit (3/4 x 1/2 In. and 1/2 x 3/8 In.) is provided for adapting to various pipe sizes.
- Electrical Connections: Connect the 24VAC wiring to the appropriate terminals on the valve. For systems requiring only two wires to energize the gas valve solenoid, connect them to the outer 'TH' and 'TR' terminals. If your system has a high-temperature safety switch already in series with the 24VAC transformer power, you may use the included jumper to bypass the unneeded high-temperature safety connection on the valve.
- Gas Type Conversion (if necessary): If converting from Natural Gas to LP or vice-versa, use the included LP conversion kit and follow its specific instructions.
- Leak Test: After all connections are made, slowly turn on the main gas supply. Check all gas connections for leaks using a non-corrosive soap solution. Bubbles indicate a leak. Tighten connections as needed and re-test.
- Pilot Light Adjustment: Refer to the appliance manufacturer's instructions for lighting and adjusting the pilot flame.
4. Operating Instructions
The White-Rodgers 36C03-333 is a standing pilot gas valve. This means a small pilot flame remains lit continuously, ready to ignite the main burner when heat is called for.
- Lighting the Pilot: Follow the specific instructions provided by your appliance manufacturer. Generally, this involves turning the gas control knob to the 'PILOT' position, pressing and holding it down, and then lighting the pilot burner. Continue holding the knob for about 30-60 seconds until the thermocouple heats up and holds the pilot flame.
- Main Burner Operation: Once the pilot is lit and stable, turn the gas control knob to the 'ON' position. When the thermostat calls for heat, the 24VAC coil in the gas valve will energize, opening the main gas flow to the burner, which will then be ignited by the standing pilot flame.
- Shutting Down: To turn off the appliance, turn the gas control knob to the 'OFF' position. This will shut off both the main burner and the pilot flame.
5. Maintenance
The White-Rodgers 36C03-333 gas valve is designed for reliable operation with minimal maintenance. However, periodic checks are recommended to ensure continued safe and efficient performance.
- Annual Inspection: It is recommended to have a qualified HVAC technician inspect your heating system, including the gas valve, annually.
- Pilot Flame Check: Periodically observe the pilot flame. It should be a steady, blue flame enveloping the tip of the thermocouple. A weak, yellow, or wavering flame may indicate a dirty pilot orifice or other issues.
- Cleanliness: Keep the area around the gas valve clean and free from dust, debris, and obstructions.
- Connections: Ensure all gas and electrical connections remain tight and free from corrosion.
6. Troubleshooting
Before attempting any troubleshooting, ensure the main gas supply is on and electrical power is supplied to the appliance. If you are unsure about any step, contact a qualified service technician.
