Product detailed description

The adapter is the first part used to connect the concentric (coaxial) flue system directly to the boiler outlet - it matches the diameter of the boiler's neck with the diameter of the chosen flue pipe. Without the correct adapter, no further flue parts can be connected to the boiler.

Frequently asked questions

• How do I check that the "Protherm flue pipe adapter 60/100 mm A1K" fits my appliance exactly? The most reliable way is to compare the exact type/catalogue designation from your appliance's rating plate (boiler, storage tank, water heater) with the compatibility stated directly in this product's name (PROTHERM brand) and in its technical parameters above. If in doubt, send us the exact type designation of your appliance (including its serial number, if available) - we will gladly verify compatibility for you.
• Why is it important to use an original/compatible part rather than a universal replacement? Parts such as seals, sensors, or safety components (safety valves, thermal fuses) are usually dimensioned precisely for the parameters of the specific appliance (pressure, temperature, sensor electrical resistance) - the wrong part can cause reduced functionality, leaks, or, in the case of safety components, a genuine 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 pressurised part of the system), a competent DIYer can usually manage the replacement after disconnecting the appliance from power and the supply lines. However, for any intervention in the gas, electrical, or pressurised part of the appliance (e.g. sensors located directly in the combustion chamber, safety valves, electrical modules), we always recommend using a service technician - especially since such work could otherwise affect the validity of the appliance's warranty.
• How do I know this part is worn and needs replacing? Common signs include visible wear/cracking (for seals and rubber parts), a leak of water or flue gas at the part, an error message on the control display (for sensors and electronic modules), or a noticeably reduced function of the appliance (e.g. irregular combustion for 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/service item? For parts that are subject to normal wear (seals, fuses, small mechanical parts) and whose failure would mean an outage of heating or hot water, keeping a spare on hand is a sensible precaution - especially for an older appliance, for which the part may be harder to obtain quickly.
