FLUE INSTALLATION
FLUE TERMINAL LOCATION
The RHFE-952ER & RHFE-1252ER flue terminal are ‘Fan Assisted’ with a maximum input of 34 MJ/
h. 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.
AS/NZS 5601 was current at the time of printing but may have been superseded.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. When installing a condensate trap kit (ESCONDK) the condensate MUST BE drained
to the inbuilt condensation drain tray of the heater (refer to “CONNECTING THE FLUE SYSTEM”
on page 23). Consult the Rinnai "Power Flued Flamefire Space Heater Co-axial Flue System
Installation Manual" supplied with flue kits ASPDFK or ASPKIT03 for further flue installation
instructions.
The flue terminal should be positioned away from flammable materials.
