4. Setup and Installation
IMPORTANT: Installation must be performed by a qualified professional in accordance with all local codes and the manufacturer's instructions.
- Preparation:
- Ensure the main gas supply to the appliance is turned off.
- Confirm that the appliance and gas lines are clean and free of debris.
- Gather all necessary tools and materials for installation.
- Mounting the Valve:
- Position the millivolt valve in a suitable location within the appliance, ensuring proper ventilation and access for service.
- Utilize the quick-mount installation system for secure and efficient placement.
- Connecting Gas Lines:
- Connect the propane gas supply line to the inlet port of the valve.
- Connect the appliance's burner line to the outlet port of the valve.
- Use appropriate pipe sealant on all threaded connections, ensuring it is resistant to propane gas.
- Tighten all connections securely, but do not overtighten.
- Pilot Assembly Installation:
- Install the complete pilot assembly according to the appliance manufacturer's instructions.
- Connect the pilot gas line from the valve to the pilot assembly.
- Connect the thermopile wires from the pilot assembly to the appropriate terminals on the millivolt valve.
- Connect the igniter wire (if applicable) to the igniter button or module.
- Electrical Connections (if applicable):
- If using a wall switch or remote control, connect the appropriate wires to the TH and TH/TP terminals on the valve, ensuring correct polarity.
- Leak Testing:
- Turn on the main gas supply.
- Apply a non-corrosive leak detection solution to all gas connections.
- Bubbles indicate a leak. If a leak is detected, turn off the gas supply, tighten the connection, and re-test. Repeat until no leaks are present.
- Initial Ignition:
- Follow the appliance's specific instructions for initial pilot lighting and burner ignition.
5. Operating Instructions
This millivolt valve operates in conjunction with your appliance's control system (e.g., wall switch, remote control, or manual knob).
- Lighting the Pilot:
- Ensure the main gas supply is on.
- Locate the pilot knob on the valve. Turn it to the "PILOT" position.
- Press and hold the pilot knob down. Simultaneously, press the igniter button repeatedly until the pilot flame lights.
- Continue to hold the pilot knob down for approximately 30-60 seconds after the pilot lights to allow the thermopile to heat up and generate sufficient millivoltage.
- Release the pilot knob. The pilot flame should remain lit. If it extinguishes, repeat the process.
- Turning On the Main Burner:
- Once the pilot is lit and stable, turn the pilot knob to the "ON" position.
- Activate your appliance's control (e.g., flip the wall switch, press "ON" on the remote) to ignite the main burner.
- Turning Off the Main Burner:
- Deactivate your appliance's control (e.g., flip the wall switch to "OFF", press "OFF" on the remote). The main burner will extinguish, but the pilot will remain lit.
- Turning Off the Entire System (including Pilot):
- Turn the pilot knob on the valve to the "OFF" position. This will extinguish both the main burner and the pilot flame.
- For extended periods of non-use, it is recommended to turn off the main gas supply to the appliance.
6. Maintenance
Regular maintenance ensures the safe and efficient operation of your millivolt valve kit. All maintenance should be performed by a qualified service technician.
- Annual Inspection: Have a qualified technician inspect the valve, pilot assembly, and all gas connections annually for wear, leaks, and proper operation.
- Pilot Assembly Cleaning: Periodically inspect the pilot burner and thermopile for dust, lint, or carbon buildup. Clean gently with a soft brush or compressed air if necessary. Ensure the pilot flame impinges correctly on the thermopile.
- Gas Line Inspection: Check gas lines for any signs of corrosion, damage, or leaks.
- Valve Operation: Ensure the valve knob turns smoothly and clicks positively into each position (OFF, PILOT, ON).
7. Troubleshooting
Before attempting any troubleshooting, ensure the main gas supply is on and all connections are secure. If you are unsure about any step, contact a qualified service technician.
