Atmos A25 Burner Combustion Chamber

Product detailed description

Atmos A25 Burner Combustion Chamber – replacement combustion chamber (cup) for Atmos A25 burners from serial no. 160

This burner bowl is designed for the Atmos A25 pellet burner without pneumatic cleaning.

If you have an Atmos A 25 pellet burner with compressor-driven pneumatic cleaning, you need this combustion chamber instead: Atmos A 25 burner combustion chamber with pneumatic cleaning

Frequently asked questions

• How do I choose the right output for a solid-fuel boiler? Base your choice on the calculated heat loss of the heated building; for wood/coal boilers also consider that the boiler burns for several hours at essentially constant output during a single load - which is why it's common practice to add a buffer (accumulation) tank to the boiler, storing surplus heat for later use instead of having to inefficiently throttle the boiler.
• What else do I need to install this boiler? Besides the boiler itself, the system usually requires: a buffer (accumulation) tank of adequate volume, a circulation pump (often already fitted with a built-in Laddomat or thermoregulatory valve against low-temperature corrosion of the boiler), a safety valve, an expansion vessel, and a flue/chimney with sufficient draught matching the boiler's output - you'll find the exact chimney draught values in the technical parameters above.
• What fuel is suitable, and what isn't? Use only fuel recommended by the manufacturer for the given model (typically split logs of a defined length and moisture content, or brown-coal briquettes or coal depending on the boiler type) - unsuitable or overly damp fuel reduces efficiency, increases tar and deposit build-up, and can damage the boiler.
• What about chimney inspection and legislation? Before putting the boiler into operation, and regularly during its use (typically once a year for solid fuels), the chimney must, by law, be inspected/cleaned by an authorised chimney sweep - without the relevant inspection certificate, an insurance claim in the event of a fire may also be disputed.
• How much maintenance does the boiler require? This usually includes regularly removing ash and cleaning the heating surfaces/flue-gas passages of soot (interval depending on intensity of use, typically on the order of weeks), plus a thorough annual inspection including seals and the chimney.
• Can I install the boiler myself? The actual placement and connection of the boiler to the heating system, chimney and safety components should be carried out, or at least professionally checked, by a heating technician - this is an appliance with an open flame, high temperatures and pressurised components, where a connection error can be a safety risk.
