Atmos Large Door Sibral Insulation - Thick

Product detailed description

Atmos Large Door Sibral Insulation – Thick (S0264)

Code S0264 denotes the original Sibral insulation for the large (upper) doors of ATMOS boilers in the thicker version. It belongs to the group of door spare parts and forms the thermal filling of the door.

Which boilers the insulation fits

The insulation is intended for the upper doors of the following boilers and series:

• D–P series: D14P, D21P, D25P, D31P
• DC series: DC75SE, DC100, DC105S, DC150S
• GSX series: DCxxGSX, GSXxx
• other designations: P14-P31, D21

Note on replacement

When replacing the Sibral door filling, it will probably be necessary to replace the sealing rope as well, which runs in a separate groove around the filling. The suitable part is the 18x18 sealing rope for large doors, which you will find in our range.

Before ordering, please check that the part matches the type of your boiler.

Frequently asked questions

• How do I choose the right output for a solid fuel boiler? Start from the calculated heat loss of the building being heated, but with wood/coal boilers also bear in mind that during one loading the boiler burns for several hours at an essentially constant output - which is why it is common practice to add a buffer tank, which stores the surplus 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 usually 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 matching the boiler output - you will find the exact chimney draught values 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 split logs of a defined length and moisture content, or brown coal briquettes or coal, depending on the boiler type) - unsuitable or too moist fuel reduces efficiency, increases the formation of tar and deposits and may damage the boiler.
• What about 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 certificate, even 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 soot from the heating surfaces/flue gas passages (the interval depends on intensity of use, usually in the order of weeks), and a thorough inspection once a year, including the seals and the chimney.
• Can I install the boiler myself? The siting of the boiler and its connection to the heating system, the chimney and the safety devices should be carried out, or at least professionally checked, by a heating technician - it is an appliance with an open fire, high temperatures and pressurised components, where an error in connection can pose a safety risk.
