Maintenance Tips
- Annual descaling/flush: Flush the heat exchanger once a year with a descaling solution to remove mineral and scale buildup and preserve flow efficiency.
- Check gas connections: Inspect propane gas lines, fittings, regulators, and valves periodically for leaks, corrosion, or loose connections; tighten or replace as needed.
- Clean water inlet filter/screens: Remove and rinse the inlet filter/screens regularly to prevent debris from reducing water flow. (General tankless practice)
- Ensure proper venting: Verify that vent pipes and exhaust paths are clear of obstructions for safe combustion and optimal performance.
- Monitor indicators: Pay attention to error codes, flame irregularities, or fluctuating temperatures; address issues promptly according to the user manual. (General tankless insight)
- Wipe exterior surfaces: Gently clean the outer unit with a soft, damp cloth; avoid abrasive cleaners that might damage coatings. (General home appliance care)
- Professional inspection: Schedule annual professional service to check propane pressure, burners, combustion safety features, and internal components for long‑term reliability. (Best practice)
