The Rinnai RBOX04L is a lockable recess box that sets a Rinnai Infinity continuous flow water heater into the wall. It suits the Infinity B16, B20 and B26 and the S20 and S26, and Rinnai's 2025 installation instructions also list the Infinity B12.
The box measures 1105mm high, 424mm wide and 150mm deep and needs a wall opening 1030–1050mm high, 365–395mm wide and 150mm deep. It can be built in as the brickwork is laid using the fold-out brick ties, or fitted into an existing wall with flush-headed masonry anchors. The base slopes 2° towards the front so any water that gets in can drain out, and cable access holes on each side allow a weatherproof power outlet to be fitted.
The water heater mounts on securing points at the top and bottom of the box, and the supplied padlock locks it in place to help reduce the risk of theft or damage. An access panel covers the area below the water heater.
