Product Details


  • Outdoor installations only
  • New construction or major renovation—installation needs to commence during the framing stage and before internal linings, cladding, or building wrap is applied.

A Rinnai INFINITY unit positioned inside a recess box operates at a slightly louder level than an INFINITY installed on an outside wall. Please keep this in mind if positioning near a bedroom as the operating noise could affect some people.

Building code compliance
Local councils may have their own requirements regarding a recess box installation, as it is similar in detail to installing a meter box. If in doubt over compliance, it is advisable to consult the local council prior to installation.
