Frequently Asked Questions

• How can I check that the "Exhaust Extension Gamat 473" fits my device exactly? The most reliable way is to compare the exact type/catalogue designation on your device's (boiler, tank, water heater) rating plate with the compatibility stated directly in this product's name (brand KARMA) and in its technical parameters above. If in doubt, send us the exact type designation of your device (including any serial number) - we will be happy to verify compatibility for you.
• Why is it important to use an original/compatible part rather than a universal replacement? Parts such as gaskets, sensors or safety components (safety valves, thermal fuses) are usually dimensioned exactly for the parameters of the specific device (pressure, temperature, sensor electrical resistance) - the wrong part can cause reduced function, leaks, or, in the case of safety components, a real safety risk.
• Does this part need to be installed by a professional? For simpler, mechanical parts (e.g. gaskets, covers, small accessories with no connection to electricity, gas or the pressurised part) a handy DIYer can usually manage the replacement after disconnecting the device from power and utilities. However, for any intervention in the gas, electrical or pressurised part of the device (e.g. sensors located directly in the combustion chamber, safety valves, electrical modules) we always recommend a service technician - especially since such an intervention could affect the validity of the warranty on the whole device.
• How do I know this part is worn and needs replacing? Common signs include visible wear/cracking (for gaskets and rubber parts), water or flue gas leaking at the part, an error message on the control display (for sensors and electronic modules), or an obviously reduced function of the device (e.g. irregular burning in burner parts). If in doubt, the safest option is to have a service technician assess the condition during the regular annual inspection.
• Is it worth keeping this part at home as a spare/service part? For parts that are subject to normal wear (gaskets, fuses, small mechanical parts) and whose failure would mean a shutdown of heating or water heating, keeping a spare is a sensible precaution - especially for an older device for which it may be harder to source the part quickly.
