Furnace frequently clogs with clinkers or hard deposits in the burn pot.

Safety first: Allow the furnace to cool completely before cleaning the burn pot.

Steps:

• 1. Clean burn pot daily (if needed): Remove clinkers and scrape the burn pot to keep air holes open.
• 2. Adjust combustion air: Increase combustion air (if adjustable) to improve burn and reduce clinker formation. Follow US Stove guidelines.
• 3. Use better fuel: Switch to premium low-ash pellets or coal recommended by US Stove. Avoid mixing brands with very different ash content.
• 4. Reduce feed rate: Lower the heat setting slightly to reduce the amount of fuel entering the pot, which can help complete combustion.
