Aluminum radiator KFA Element left G 500 F/D, bottom connection, 50×50 mm straight connection set, cross-fed (878-052-44)

Aluminum radiator KFA Element left G 500 F/D is a left-oriented panel radiator with bottom (lower) supply designed for central heating systems. Manufactured from pressed and welded aluminium panels, the radiator provides a compact and lightweight heat emitter with a left-side orientation and lower inlet/outlet arrangement. The product comes with a straight connection set sized 50×50 mm and supports cross-feed piping layouts, making it compatible with installations that require bottom connections and flexible piping routes.

Advantages

The radiator’s aluminium construction ensures fast thermal response and reduced weight compared to steel counterparts, facilitating handling and installation. Bottom connection design with a 50×50 mm straight connection set enables neat aesthetic integration and concealed piping in modern interiors. Support for cross-fed piping increases installation flexibility, allowing the radiator to be connected in systems where supply and return are routed across or beneath the unit.

Suitable for

• Residential rooms with limited wall depth or where a lower supply is required
• Commercial spaces requiring compact, lightweight radiators
• Renovation projects where existing plumbing uses bottom or cross-feed connections
• Situations demanding quick thermal response and efficient heat transfer

Key specifications

• Material: aluminium panels
• Orientation: left-sided radiator design
• Supply type: bottom (lower) inlet and outlet
• Connection set: straight connection set 50×50 mm
• Compatibility: supports cross-fed piping configurations
• Application: central heating systems for residential and commercial buildings

How to use

Install the radiator on a suitable load-bearing wall using appropriate mounting brackets and ensure the unit is level. Connect the straight 50×50 mm bottom connection set to the supply and return pipes according to the left orientation and the chosen cross-feed arrangement. Flush the heating circuit before connection, and fill the system with the recommended heating medium and corrosion inhibitors when applicable. After filling, bleed air from the radiator using the bleed valve and adjust balancing valves if present to achieve the required heat output.

Usage recommendations

During installation, verify pipe dimensions and thread compatibility with the 50×50 mm connection set and confirm left-side orientation matches the intended piping layout. For optimal performance, ensure regular system maintenance, periodic bleeding to remove trapped air, and use of inhibitors suitable for aluminium radiators to prevent corrosion and prolong service life.
