Maintaining your wood burning sauna stove is key to preserving its efficiency, safety, and longevity. In this guide, we’ll walk you through essential maintenance tips that will help you keep your stove in peak condition for years to come. 

Why Maintenance Matters for Your Wood Burning Sauna Stove 

Wood burning sauna stoves are crafted to withstand high temperatures and daily use, but like any piece of equipment, they require regular care to operate safely and efficiently. Without proper maintenance, your stove can develop issues such as poor heat output, inefficient fuel consumption, smoke leakage, or even hazardous conditions. 

According to the National Fire Protection Association (NFPA), failure to maintain wood-burning appliances properly contributes to more than 25,000 home fires annually in the U.S., underscoring the importance of routine care and inspection. 

By performing routine upkeep, you can: 

• Extend the lifespan of your stove 

• Ensure optimal heating efficiency 

• Prevent dangerous buildup of creosote and ash 

• Reduce risk of chimney fires 

• Save money on fuel and repairs 

Top Maintenance Tips for Your Wood Burning Sauna Stove 

Clean the Firebox Regularly 

The firebox is where the wood burns, so it accumulates ash and debris after every use. Cleaning it regularly ensures better airflow and more efficient combustion. 

• How often: After every few sauna sessions or at least weekly during heavy use 

• Method: Wait for the stove to cool completely, then scoop out the ash using a metal ash shovel. Dispose of the ash safely in a metal container. 

• Tip: Avoid letting ash buildup exceed 2-3 inches to maintain optimal airflow. 

 Inspect and Clean the Chimney and Flue 

Creosote buildup inside your chimney and flue can lead to chimney fires and reduced stove performance. Creosote is a sticky, flammable substance created when wood smoke condenses on cooler surfaces. 

• How often: At least once per sauna season, or more frequently if used heavily 

• Method: Use a chimney brush to clean the flue, or hire a professional chimney sweep for thorough cleaning and inspection. 

• Safety Note: Check that the chimney cap is intact and free from debris or bird nests. 

Check the Stove Door Gaskets 

The stove door gasket ensures a tight seal, preventing smoke leaks and maintaining heat efficiency. Over time, gaskets may degrade or become loose. 

• How often: Inspect every 3-6 months 

• Method: Look for cracks, wear, or gaps in the gasket. Replace the gasket if damaged; SplashBlaze™ offers replacement parts for various models. 

• Pro Tip: When installing a new gasket, ensure it’s the correct size and firmly attached. 

Examine the Glass Door (If Applicable) 

Many wood burning sauna stoves have tempered glass doors for viewing the fire. Keeping the glass clean improves aesthetics and allows you to monitor the fire. 

• How often: After every few uses or as needed 

• Method: Use a specialized stove glass cleaner or a mixture of vinegar and water. Avoid abrasive materials that can scratch the glass. 

• Warning: Clean only when the glass is cool to prevent cracking. 

Monitor and Maintain Stove Paint or Finish 

Heat from the stove can cause paint or surface finishes to deteriorate over time. 

• How often: Inspect every sauna season 

• Method: Touch up with heat-resistant stove paint as necessary, following manufacturer guidelines. 

• Benefit: Maintains the stove’s appearance and protects against rust and corrosion. 

Use Proper Wood Fuel 

The type and quality of wood you burn directly affect stove performance and longevity. 

• Recommended: Dry, seasoned hardwood such as oak, maple, or birch with less than 20% moisture content. 

• Avoid: Wet, green wood or softwoods that produce excess creosote and smoke. 

• Tip: Store wood in a dry, ventilated area for at least 6-12 months before burning. 

Inspect the Air Vents and Controls 

Air vents regulate the oxygen supply to the fire, influencing heat output and fuel consumption. 

• How often: Check monthly during sauna use 

• What to do: Ensure vents are free of debris or ash, and that controls move smoothly. 

• Result: Proper airflow improves combustion efficiency and temperature control. 

Schedule Annual Professional Inspections 

While many maintenance tasks are DIY-friendly, an annual professional inspection adds an extra layer of safety and performance assurance. 

• Service includes: Chimney sweep, stove inspection, gasket replacement advice, and safety check. 

• Benefit: Identifies potential issues early, prevents hazards, and prolongs stove life.
