Rinnai P50IVR-006 HD50i Front Panel Kit – (P50IVR-006) The Rinnai HD50i is a 54kW, fully modulating wall-mounted continuous flow water heater, equally suited to commercial and industrial installations as it is to a large domestic property, with the expectation of running reliably day after day. When the front panel needs replacing — whether from accidental damage, general wear, or as part of a thorough repair — a proper fitting part matters more than a substitute that'll do for now. The P50IVR-006 is the genuine Rinnai front panel kit for the HD50i, built to the same specification as the one fitted at the factory, so it integrates cleanly with the appliance's controls and internal fittings without adjustment. ⚠ Important: This is a gas appliance repair and must be carried out by a Gas Safe registered engineer.
