For Rinnai External continuous flow water heaters such a building structure must ‘obstruct’ the full front cover height of the appliance, or extend vertically above and below the front cover.

    Rinnai Heavy Duty Units require a minimum of either 1.5 l/min or 2.4l/min (depending on which water heater is used) per heater before they can operate. If this is not achieved they will not fire. When there is an expected scenario that results in a lower flow per heater a staging system is required.
  • Page 20: Fault Finding

    MANIFOLD PACK PREVENTATIVE MAINTENANCE Your Rinnai Continuous Flow water heaters have self diagnostic capability. If a fault occurs, an Error Code will flash on the status monitor or inbuilt controller. If you have Water Controllers, this assists with diagnosing the fault and may enable you to overcome a problem without a service call.

    This may be indicated by Fault 10. Contact Rinnai Service. • Internal heaters may operate for a short period of time and then stop. This can be caused by Rinnai Co-axial flueing not being pushed together properly and exhaust gases are re-entering the inlet air. Check flue connections.
