Operation
The White-Rodgers 36H32-423 gas valve features a simple ON/OFF control and an adjustable regulator.
Gas Flow Control:
- ON Position: Allows gas to flow through the valve when called for by the appliance's control system.
- OFF Position: Shuts off the gas supply to the appliance. This position should be used for servicing or extended periods of non-use.
Regulator Adjustment:
The gas pressure regulator is factory set to 3.5" W.C. (Water Column). If adjustment is necessary, it should only be performed by a qualified technician using a manometer to measure outlet pressure. The 'REG. ADJUST' screw on the valve allows for fine-tuning of the gas pressure.
Maintenance
The White-Rodgers 36H32-423 gas valve is designed for reliable operation with minimal maintenance. However, periodic checks by a qualified technician are recommended as part of routine appliance servicing.
- Annual Inspection: Have a qualified technician inspect the valve and gas connections annually for signs of wear, leaks, or corrosion.
- Cleaning: Ensure the inlet/outlet screens remain clear of debris. Do not attempt to clean internal components.
- Operational Check: Verify that the ON/OFF switch operates smoothly and that the valve opens and closes correctly.
Troubleshooting
If you experience issues with your gas appliance, consult a qualified technician. Do not attempt to repair the gas valve yourself.
Common Issues (Technician Only):
- No Gas Flow: Check if the valve is in the 'ON' position. Verify gas supply to the appliance. Inspect electrical connections and control signals.
- Pilot Light Issues: If the pilot light fails to ignite or stay lit, the valve's pilot section or associated controls may require inspection.
- Irregular Burner Operation: Fluctuations in gas pressure or flow can indicate a regulator issue or obstruction within the valve.
