Maintenance Tips

• Clean ash regularly: Remove ash buildup after each few burns to maintain strong airflow and efficient combustion.
• Inspect chimney & flue (monthly): Keep smoke path clear to prevent reduced draft, smoke backup, or weak heating.
• Use only dry, seasoned wood: Moist wood lowers heat output, creates excess smoke, and increases soot buildup.
• Maintain proper airflow control: Ensure air vents and dampers are not blocked for clean, efficient burning.
• Check stone placement (if stone basket used): Keep sauna stones loosely arranged to improve heat transfer and steam quality.
• Remove soot from fire chamber: Light cleaning helps preserve stainless steel surfaces and improves long-term durability.
• Inspect door seals & hinges: Ensure tight closure for safe combustion and stable heat retention.
• Keep surrounding area heat-safe: Maintain proper clearances and fire-safe surfaces around the heater.
• Seasonal deep inspection: Before heavy use, check chimney integrity, internal buildup, and general wear.
