Maintenance Tips
-
Empty ash box before every use: Improves combustion airflow, protects the fire grate, and ensures faster, cleaner heating cycles.
-
Clean ash & soot channels regularly: Remove buildup from smoke passages to maintain efficient heat output and reduce fire risk.
-
Sweep chimney and flue frequently: Prevents blockage, improves draft, and reduces creosote/fire hazards—especially in heavy use.
-
Re-stack sauna stones (at least annually): Stones crack from heat cycles; replace broken ones and keep loose spacing for proper airflow and steam quality.
-
Use only dry, seasoned wood: Ensures clean burn, higher heat efficiency, and less soot accumulation.
-
Maintain proper stone placement: Do not overpack—airflow through stones is essential for stable heating performance.
-
Check fire chamber & door seals: Ensures safe combustion, strong draft, and consistent heat retention.
-
Wipe exterior surfaces after cooling: Removes ash dust and moisture to prevent corrosion and maintain durability.
-
Inspect ventilation & air intake: Good airflow prevents smoke issues and improves burn efficiency in medium-sized sauna rooms.
