Frequently asked questions

• How can I check that the “Firebox Side Seal DC0163” fits my appliance exactly? The most reliable way is to compare the exact type/catalogue designation from the rating plate of your appliance (boiler, storage tank, water heater) with the compatibility stated directly in the name of this product (brand Atmos) and in its technical parameters above. If in doubt, write to us with the exact type designation of your appliance (including the serial number, if applicable) - we will be happy to verify the compatibility for you.
• Why is it important to use the original/compatible part and not a universal replacement? Parts such as seals, sensors or safety elements (safety valves, thermal fuses) are generally dimensioned precisely for the parameters of the specific appliance (pressure, temperature, electrical resistance of the sensor) - an incorrect part can cause reduced functionality, leaks or, in the case of safety elements, 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 piping. 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), however, we always recommend a service technician - especially if the intervention could affect the warranty on the entire appliance.
• How do I know that this part is worn and needs replacing? Common signs are visible wear/cracking (on seals and rubber parts), water or flue gas leaking at the part, an error message on the controller display (for sensors and electronic modules), or clearly reduced functionality of the appliance (e.g. irregular burning with burner parts). If in doubt, it is safest to have the condition assessed by a service technician 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 shutdown of heating or water heating, keeping a spare in stock is a sensible precaution - especially for an older appliance, for which it may be more difficult to get the part quickly.
