• Inspect LP gas line and regulator for leaks, corrosion, or loose fittings before use
• Ensure outdoor installation area is clear of debris for proper airflow and safe operation
• Check freeze protection system and drainage path to prevent cold-weather damage
• Descale heat exchanger in hard-water areas to avoid temperature fluctuations
• Maintain proper water pressure for stable and consistent hot water output
• Keep exterior casing clean and dry; prevent insect or dirt blockage in vents
• Inspect temperature sensors and control panel for error codes and address early
• Shut off gas and water supply before any maintenance or servicing
• Do not use for hydronic heating, floor heating, or recirculating systems
• For scratch & dent units, periodically inspect casing and fittings for hidden damage or impact wear
