4. Setup and Installation
IMPORTANT: Installation must be performed by a qualified and licensed gas technician in accordance with all applicable local and national codes.
- Preparation: Ensure the gas supply to the appliance is completely shut off and disconnected. Verify that the new valve matches the specifications of the original valve and is suitable for natural gas.
- Removal of Old Valve: Carefully disconnect all gas lines and electrical connections (thermocouple/thermopile wires) from the old valve. Remove the old valve from the appliance.
- Installation of New Valve:
- Apply appropriate pipe sealant (suitable for natural gas) to all threaded gas connections.
- Connect the gas inlet line (1/2") to the valve.
- Connect the main gas outlet line (3/4") and any side outlet lines (1/2") to the valve.
- Connect the pilot gas line to the designated pilot outlet on the valve.
- Connect the thermocouple or thermopile wires to the millivolt terminals on the valve. Ensure correct polarity if specified.
- Leak Testing: After all connections are made, slowly turn on the main gas supply. Apply a soap and water solution to all gas connections to check for leaks. Bubbles indicate a leak, which must be corrected immediately.
- Pilot Adjustment: If applicable, adjust the pilot flame according to the appliance manufacturer's instructions to ensure it properly engulfs the thermocouple/thermopile.
5. Operating Instructions
The Garland 700 Series Millivolt Combination Valve operates in conjunction with a millivolt thermostat system. Follow the specific lighting and operating procedures provided by the manufacturer of the appliance in which this valve is installed.
General Operating Sequence:
- Pilot Lighting: Turn the gas control knob to the "PILOT" position. Depress the knob and light the pilot flame. Continue to hold the knob for approximately 30-60 seconds until the thermocouple/thermopile generates sufficient millivoltage to hold the pilot valve open. Release the knob; the pilot should remain lit.
- Main Burner Operation: Turn the gas control knob to the "ON" position. Set the appliance's thermostat to the desired temperature. The main burner should ignite when the thermostat calls for heat.
- Shut Down: To turn off the main burner, set the thermostat to its lowest setting or "OFF". To completely shut down the appliance, turn the gas control knob to the "OFF" position.
If the pilot flame goes out, wait at least five (5) minutes to clear any accumulated gas before attempting to relight it.
6. Maintenance
Regular maintenance ensures the longevity and safe operation of your gas control valve. All maintenance should be performed by a qualified service technician.
- Annual Inspection: Have the gas control valve and associated components (thermocouple/thermopile, pilot burner, main burners) inspected annually for wear, corrosion, and proper operation.
- Cleaning: Keep the area around the gas valve clean and free from dust, grease, and debris. Ensure ventilation openings are not obstructed.
- Pilot Flame Check: Periodically check the pilot flame for proper size and color (a steady blue flame). A weak or yellow pilot flame may indicate a need for cleaning or adjustment.
- Leak Check: Perform a gas leak check with a soap solution after any maintenance involving gas connections.
7. Troubleshooting
Before attempting any troubleshooting, ensure the gas supply is on and the appliance is properly connected. For complex issues, contact a qualified service technician.
