Low power 1. Low fuel combustion heat or high fuel moisture. Use recommended fuel with defined moisture content.
-//- 2. Low draft. Check the draft in the flue and the compliance of the pipe with the manufacturer's recommendations.
-//- 3. Soot deposits in the gas passages and/or flue gas collector. Clean the surface of the furnace and flue passages from accumulated soot.

It is impossible to regulate the operation of the boiler. 1. The ash door does not close tightly. Check the sealing cord and the door fastener.
-//- 2. Strong draft in the chimney and/or high heat output of the fuel. Adjust the chimney damper. Install a draft limiter.
The temperature of the flue gases exceeds the passport values. Strong draft in the chimney and/or clogged heat transfer surfaces. Adjust the chimney damper. Clean the surfaces of the furnace and flue passages from soot and resin.
