Nozzle DC0133

Product detailed description

ATMOS DC0133 ceramic nozzle

The oldest of the three nozzles used successively in the DC50S boiler – it belongs to units manufactured no later than 31 Dec 2009. The same nozzle is also used in the DC50 type.

Which boilers it fits

• DC50,
• DC50S with a production date up to 31 Dec 2009.

What comes with the nozzle

Besides the original nozzle, the package includes sealing cement and three sealing cords. They are used to seal the front and both sides.

Don't forget the block

Behind the nozzle in the DC50S boiler there is also an extension – a 200 × 200 mm ceramic block. It is not supplied with the nozzle and must be ordered separately: block DC0031 – nozzle extension.

Frequently asked questions

• How do I choose the right output for a solid fuel boiler? Start from the calculated heat loss of the heated building, but with wood/coal boilers also consider that the boiler burns for several hours per load at essentially constant output - which is why it is common practice to add a heat accumulation tank to the boiler, which stores the excess heat for later use instead of the boiler having to be throttled down inefficiently.
• What else do I need to install this boiler? Besides the boiler itself, the system generally requires: a buffer (accumulation) tank of suitable volume, a circulation pump (often already with a built-in Laddomat or a thermostatic valve protecting the boiler against low-temperature corrosion), a safety valve, an expansion vessel, and a flue/chimney with sufficient draught corresponding to the boiler output - the exact chimney draught values can be found in the technical parameters above.
• Which fuel is suitable and which is not? Use only the fuel recommended by the manufacturer for the given model (usually log wood of defined length and moisture content, or brown coal briquettes or coal depending on the boiler type) - unsuitable or overly moist fuel reduces efficiency, increases the formation of tar and deposits, and can damage the boiler.
• What about the chimney inspection and legislation? Before the boiler is put into operation, and also regularly during its use (usually once a year for solid fuels), an inspection/cleaning of the chimney by an authorised chimney sweep is required by law - without the relevant inspection report, an insurance claim in the event of a fire may be disputed.
• How much maintenance does the boiler require? It usually includes regular removal of ash and cleaning of the heating surfaces/flue gas passages from soot (the interval depends on intensity of use, usually in the order of weeks), and a thorough annual inspection including the seals and the chimney.
• Can I install the boiler myself? The placement and connection of the boiler to the heating system, the chimney and the safety components should be carried out, or at least professionally checked, by a heating technician - it is an appliance with an open fire, high temperatures and pressure components, where a connection error can pose a safety risk.
