Installation & Maintenance Tips
- Always shut off gas and power before service, and leak-test all gas connections after installation.
- If ignition issues persist after replacement, confirm proper gas supply pressure, clean burners, correct grounding/bonding, and unobstructed combustion air.
- Keep the heater cabinet area clear of leaves and debris—restricted airflow can cause poor combustion and safety trips.
- Maintain proper water flow and clean filtration; low flow can cause overheating and shutdowns that mimic ignition problems.
