## Summary description

Replacement seal (gasket) by GEKO designed for a 25 kW oil heater with a flue gas outlet. This component provides tight sealing at the connection points of the heater and the exhaust system to prevent leaks of oil, combustion gases and ensure safe operation. Suitable for maintenance and repair of compatible oil-fired heating units.

## Long description

Seal Geko for 25 kW Oil Heater with Flue Gas Outlet is a replacement gasket designed to restore and maintain airtight connections between the heater body and the flue gas outlet on compatible 25 kW oil-fired heating units. Manufactured for compatibility with GEKO systems, the seal prevents leaks of combustion gases and oil residues, supporting safe and efficient operation during heating cycles. The component is intended for routine maintenance and repair, offering a straightforward means to address worn or damaged seals that compromise exhaust tightness.
Advantages
The gasket provides a reliable radial seal that resists temperature and pressure conditions typical for 25 kW oil heaters with flue exhausts, helping to reduce the risk of exhaust leakage and unintended fuel or soot escape. Its design facilitates replacement with minimal disassembly of the exhaust connection and contributes to maintaining combustion efficiency. Made to fit the relevant connection dimensions, the seal supports continued safe operation and eases servicing tasks.
Suitable for
Repairing or replacing a worn seal on 25 kW oil-fired heaters with a flue gas outlet
Routine maintenance during annual service of oil heating systems
Preventive replacement after detection of exhaust leaks, soot buildup, or gasket degradation
Key specifications
Application: gasket for oil-fired heater flue gas outlet
Compatible heat output category: 25 kW class oil heaters
Function: provides airtight seal at exhaust connection to prevent combustion gas and oil leakage
Material characteristics: designed for exposure to combustion gases and elevated temperatures (material composition suited for heater exhaust use)
Installation: replacement component sized for standard flue gas outlet connection on compatible units
How to use
Shut down the heater, allow all components to cool and isolate fuel and electrical supplies before beginning work. Access the flue gas outlet connection, remove any retaining fasteners and extract the old seal. Clean mating surfaces of soot, corrosion and debris to ensure a flat contact area. Position the replacement gasket evenly around the connection interface and reassemble the exhaust connection, tightening fasteners to the manufacturer’s recommended torque. After installation, inspect the sealing area visually and perform a functional test by briefly operating the heater while checking for exhaust leaks and correct draft.
Usage recommendations
Use this gasket as part of regular maintenance schedules and replace it immediately if signs of cracking, deformation, soot leakage or corrosion appear. Ensure compatibility with the specific heater model before installation and follow the heater manufacturer’s service instructions. If unsure about fitting or if persistent leaks are detected after replacement, seek assistance from a qualified heating technician.
