• Inspect outdoor unit housing & burner area for dust, insects, spider webs, and debris that can block airflow
• Check water and gas connections periodically for leaks, corrosion, or loose fittings
• Flush system before heavy-use seasons to keep heat exchanger efficient and responsive
• Protect from freezing conditions by draining the unit or using built-in freeze protection properly
• Keep temperature around 120°F to reduce scaling and improve efficiency
• Ensure proper clearance around unit for safe ventilation and combustion airflow
• Test ignition and error codes occasionally to catch early performance issues
