Buying Guide
Key considerations when choosing a pilot light assembly kit:
- Compatibility: Confirm model and serial compatibility with your water heater or RV heater. Look for explicit model lists or a universal compatibility claim.
- Thermocouple length: Standard lengths are 24 inches; ensure the included thermocouple matches your unit’s expectations to avoid ignition timing issues.
- Included components: Some kits include the thermocouple, tubing, and gas line; others require separate purchases. Verify what’s included to meet your installation needs.
- Installation requirements: Gas shutoff and basic tools are typically needed. Follow the manufacturer’s safety instructions to avoid leaks or improper ignition.
- Durability and materials: Stainless portions and corrosion-resistant connectors contribute to longer life in heat and humidity environments.
- Warranty and support: A limited warranty or easy access to customer support can be helpful if compatibility questions arise.
- Installation environment: RV use, residential homes, and commercial settings may have different venting and safety considerations. Choose kits designed for your setting.
