5. インストール手順

重要： Installation should only be performed by a qualified HVAC technician. Failure to follow these instructions can result in property damage, personal injury, or death.

1. 安全第一: メインサービスパネルで炉へのすべての電源をオフにしてください。炉の手動ガス遮断弁を閉じてください。
2. アクセスイグナイター: Locate and remove the furnace access panel(s) to expose the burner assembly and ignitor.
3. 古いイグナイターを外します: Carefully disconnect the wiring harness from the old ignitor. Note the routing of the wires.
4. 古いイグナイターを取り外す: Unscrew or unclip the old ignitor from its mounting bracket. Handle it gently as it may be fragile.
5. 取り付けの検査: Examine the mounting bracket for any damage or corrosion. Clean if necessary.
6. 新しいイグナイターをインストールします: Carefully mount the new MARS 67915 ignitor onto the bracket using the original hardware or suitable replacements. Ensure it is securely fastened and positioned correctly according to the furnace manufacturer's specifications. Avoid touching the black ignitor element.
7. 配線を接続: Connect the new ignitor's wiring harness to the furnace control board or existing wiring, ensuring a secure and correct connection. The MARS 67915 comes with 36-inch leads and a connector for direct replacement.
8. セキュアパネル: Replace all furnace access panels securely.
9. 電力とガスの復旧: Open the manual gas shut-off valve. Restore electrical power to the furnace.
10. テスト操作: サーモスタットで熱要求を開始し、炉の点火シーケンスを観察して、新しい点火装置が点灯し、ガスバーナーが適切に点火することを確認します。

6. 動作原理

The MARS 67915 is a hot surface ignitor. When the furnace calls for heat, the control board sends voltage to the ignitor, causing its silicon carbide element to heat up rapidly to a very high temperature (typically over 1800°F or 980°C). Once the ignitor reaches its optimal temperature, the gas valve opens, allowing gas to flow over the hot ignitor, which then ignites the gas. After successful ignition, the ignitor typically de-energizes, and the flame sensor confirms the presence of a flame.

7. メンテナンス

The MARS 67915 ignitor is a sealed component and does not require routine user maintenance. However, regular professional furnace maintenance is recommended to ensure optimal performance and longevity of all furnace components, including the ignitor.

• During annual furnace inspections, a qualified technician should visually inspect the ignitor for cracks, discoloration, or signs of wear.
• Ensure the area around the ignitor and burner assembly is free from dust, debris, and obstructions.

8。 トラブルシューティング

If your furnace is not igniting, and you suspect the ignitor, consider the following common issues. Always ensure safety precautions are followed before any inspection.

• Ignitor Not Glowing:
  • Check for power to the furnace.
  • Verify wiring connections to the ignitor are secure.
  • The ignitor itself may be faulty or broken. A qualified technician can test its resistance.
• Ignitor Glows but No Ignition:
  • Check if the gas supply to the furnace is open.
  • Ensure the ignitor is positioned correctly to ignite the gas stream.
  • There might be an issue with the gas valve or furnace control board.
  • The ignitor may not be reaching sufficient temperature to ignite the gas.
• Furnace Cycles On and Off Rapidly: This could indicate a problem with the flame sensor, which works in conjunction with the ignitor.

For complex issues, it is highly recommended to contact a certified HVAC professional.
