Frequently asked questions

• How can I check that the "DC0031 Block - nozzle extension" fits my appliance exactly? The most reliable way is to compare the exact type/catalogue designation on the rating plate of your appliance (boiler, storage tank, water heater) with the compatibility stated directly in the name of this product (Atmos brand) and in its technical parameters above. If in doubt, send us the exact type designation of your appliance (including the serial number, if applicable) and we will gladly verify compatibility for you.
• Why is it important to use the original/compatible part rather than a universal replacement? Parts such as seals, sensors or safety components (safety valves, thermal fuses) are generally rated precisely for the parameters of the specific appliance (pressure, temperature, electrical resistance of the sensor) - an incorrect part may cause reduced performance, leaks or, in the case of safety components, a real safety risk.
• Does this part have to be installed by a professional? For simpler, mechanical parts (e.g. seals, covers, small accessories with no connection to electricity, gas or the pressure circuit), a skilled DIY enthusiast can usually handle the replacement after disconnecting the appliance from the power supply and the pipework. However, for any work on the gas, electrical or pressure part of the appliance (e.g. sensors directly in the combustion chamber, safety valves, electrical modules) we always recommend a service technician - especially if the intervention could affect the warranty of the entire appliance.
• How do I tell that this part is worn and needs replacing? Common signs are visible wear/cracking (for seals and rubber parts), water or flue gas leaks at the part, an error message on the controller display (for sensors and electronic modules), or clearly reduced performance of the appliance (e.g. irregular combustion with burner parts). If in doubt, it is safest to have a service technician assess the condition during the regular annual inspection.
• Is it worth keeping this part at home as a spare? For parts that are normally subject to wear (seals, fuses, small mechanical parts) and whose failure would mean a heating or hot water outage, keeping a spare is a sensible precaution - especially for an older appliance, for which the part may be harder to obtain at short notice.
