This stainless flange is the larger Cilindro embedding ring for the 10.5 kW PC110E on this shop. Not HPC2 (6 / 8 / 9 kW). Not a chimney. Not the LED flange.
How it is used
Same job as HPC2: bench cutout, heater through the hole, flange covers the rim and shields the bench. SSB and the dealer catalog name this SKU for 10.5 kW / 11 kW-class Cilindro. We map it only to harvia-cilindro-pc110e. Harvia’s EU page also mentions Cilindro Pro PC165E/200E — we do not invent those onto this US shop listing.
