5. Setup and Installation
WARNING: Installation must be performed by a qualified service technician. Failure to follow these instructions can result in fire, explosion, or carbon monoxide poisoning.
- Preparation: Ensure the gas supply to the appliance is turned off and the appliance has cooled completely. Disconnect electrical power if applicable.
- Access: Carefully remove any panels or components necessary to access the existing pilot assembly within your direct vent appliance.
- Removal of Old Assembly: Disconnect the gas line, igniter wire, and thermocouple/thermopile wires from the old pilot assembly. Unfasten the mounting screws and remove the old assembly.
- Installation of New Assembly: Position the new H7268 pilot assembly in the same location as the old one. Secure it with the appropriate mounting screws.
- Connections:
- Connect the gas supply line to the pilot assembly. Ensure a tight, leak-free connection.
- Connect the igniter wire to the appropriate terminal.
- Connect the thermocouple/thermopile wires to the gas valve or control module as per the appliance manufacturer's instructions.
- Leak Test: Turn on the gas supply and check all connections for leaks using a gas leak detection solution. Bubbles indicate a leak. Tighten connections as needed and re-test.
- Reassembly: Replace any panels or components removed during access.
6. Operating Instructions
The H7268 pilot assembly operates as part of your appliance's ignition system. Once installed correctly, its operation is typically automatic or initiated by the appliance's control system.
- Initial Startup: After installation, follow your appliance's specific instructions for initial startup. This usually involves turning on the gas supply and initiating the ignition sequence.
- Pilot Ignition: The electronic igniter will spark, igniting the pilot flame. The thermocouple/thermopile will sense this flame, signaling the gas valve to open and allow gas to flow to the main burner.
- Main Burner Operation: Once the pilot is established, the main burner will ignite, and the appliance will operate as designed.
- Shutdown: To turn off the appliance, follow the manufacturer's instructions. The pilot flame may remain lit or extinguish depending on the appliance's design.
7. Maintenance
Regular inspection and maintenance ensure the longevity and safe operation of your pilot assembly.
- Annual Inspection: It is recommended to have a qualified service technician inspect the pilot assembly and the entire gas appliance annually.
- Pilot Flame Check: Periodically observe the pilot flame. It should be steady, blue, and impinge directly on the thermocouple/thermopile tip. A weak, yellow, or wavering flame may indicate a problem.
- Cleaning: If the pilot burner or igniter electrode appears dirty or obstructed, gently clean it with a soft brush or compressed air. Ensure the gas supply is off before cleaning. Do not use abrasive materials.
- Wire Connections: Check all electrical and gas connections for tightness and signs of wear or corrosion.
8. Troubleshooting
If your appliance is not operating correctly, consult this troubleshooting guide. For complex issues, contact a qualified service technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pilot will not light | No gas supply, faulty igniter, obstructed pilot orifice, loose wiring. | Check gas valve, inspect igniter for damage, clean pilot orifice, check all electrical connections. |
| Pilot lights but main burner does not ignite | Faulty thermocouple/thermopile, gas valve issue, low gas pressure. | Ensure pilot flame impinges on thermocouple/thermopile, check thermocouple/thermopile for proper voltage, consult a technician for gas valve or pressure issues. |
| Pilot flame is weak or yellow | Partially obstructed pilot orifice, low gas pressure, air in gas line. | Clean pilot orifice, bleed air from gas line (if safe to do so), consult a technician for gas pressure issues. |
| Pilot goes out frequently | Drafts, faulty thermocouple/thermopile, loose connections. | Check for drafts, ensure thermocouple/thermopile is properly positioned and functioning, tighten connections. |
