1. Heater Owner's Manual.
2. Example Compliance Certificate
3. Data Plate Example (from inside the heater). Only for your service technician.
While your heater will have a Brivis or Rinnai logo on the outer case, it may not be visible to you. In most cases, your Wall Control will also have the Brivis or Rinnai logo. On occasion, third party controllers are fitted, so it is important to confirm with information from the appliance, not the controller.
