Vytautas engineering compatibility note (50-003-620)
Verified mating components for Ferroli (50-003-620) matched by connection standard (DN / thread / M30×1.5 / RA Click) and hydraulic compatibility.
Yes, this Ferroli unit (SKU 50-003-620, category: Radiators & convectors) is manufactured to European EN 12828 hydronic standards. Verify the connection thread or nominal size (e.g. DN15 1/2", DN20 3/4", M30×1.5 or Danfoss RA Click) – our engineering advisor Vytautas lists directly compatible mating components on this page.
Genuine Ferroli components use corrosion-resistant alloys (DZR brass, bronze or stainless steel) and calibrated flow paths, preventing valve sticking, water-hammer noise and premature seal leaks over 10+ heating seasons.
When installing Vandeninis konvektorius – fancoil šildymo ir vėsinimo prietaisas Ferroli Top Fan 20 (1,95 kW, 2 vamzdžių sistema) (50-003-620, retail price 22,17 €), check whether you need matching union tailpieces, Eurocone adapters, a mating thermostatic head or actuator. See the compatible parts section above.
Always observe the flow-direction arrow on the housing, depressurise the loop before fitting, and never apply hemp or tape onto flat union gaskets or O-ring cones.
Plieninis radiatorius Tipas 22 K turi 4×G 1/2" šoninį pajungimą, o laikikliai, aklė ir nuorintojas jau yra komplekte. Jam reikalingas šoninis DN15 vožtuvas (013G0014 arba 3933-02.000) – apatinio pajungimo VK 50 mm binoklis šiam modeliui netinka.

Verification note: Solid-fuel boiler door aperture and flange dimensions vary by production year and kW rating – before ordering a door conversion kit or pellet burner, verify exact dimensions against the boiler passport or with a „Gilės inžinerija“ engineer (+370 611 19158).
Confirm that 50-003-620 connection matches the supply/return pipework and flow direction arrow.
Depressurise the heating circuit, fit the union tailpiece and tighten to factory torque.
Adjust the flow scale (Kvs / l/h) or controller setting according to room or boiler loop load.
Refill the loop, vent trapped air and verify leak-free operation under operating temperature.
Engineer pro tip: When installing Ferroli (50-003-620), never wind hemp onto flat gasket seats or Eurocone O-ring cones – seal only tapered pipe threads.
