FLUE TERMINAL LOCATION
Ensure that the location of the flue terminal can comply with the requirements of AS/NZS 5601 -
Fig. 6.2 which is reproduced in part below.
WARNING
AS/NZ 5601 was current at the time of printing but may have been superseded. It is the installer's
responsibility to ensure that requirements of the current version of AS/NZS 5601 are met.
The flue system must be fully assembled and secured in place before the heater is installed into
the enclosure.
Refer to separate Flueing Installation Manual for Rinnai Flamefire heaters.
