Installation Manual
HEATER LOCATION
When positioning the heater the main variables governing the location are Flueing and Warm Air
Distribution.
This heater must not be installed where curtains or other combustible materials could come into
contact with it. In some cases curtains may need restraining.
ENCLOSURE REQUIREMENTS
As the Rinnai RHFE-752ETR has a cool outer casing it can be installed into existing Masonry fireplace
or into a decorative fireplace constructed from combustible materials such as wood or plaster.
A pair of wheels located at the rear the heater allows it to slide
in and out of the enclosure for ease of commissioning and
maintenance. As such the heater must be positioned on a flat
and level surface that allows free movement.
In a masonry fireplace, use a slurry of sand and cement to
level the base as required.
In a decorative fireplace, if the appliance is elevated from the
ground, a base must be constructed using a board with
supporting joists as shown.
WALL PENETRATION REQUIREMENTS
Mark the location of the gas supply (consumer piping) and flue
pipe penetrations form the centreline
of the heater enclosure
using the following dimensions:
Consideration must be given to the position of any studs,
noggins or other components of the wall structure.
For all installations, ONLY Rinnai ASP & ES Flue components MUST BE used. The Rinnai
RHFE-752ETR MUST NOT be flued into ‘natural draft’ flue system or via a chimney.
Consult the Rinnai “Power Flued Flamefire Space Heater Co-axial Flue System Installation
Manual” supplied with flue kits ASPDFK or ASPKIT03 for detailed flue installation
instructions.

The enclosure dimensions specified are critical to the successful installation of this
appliance and must be strictly adhered to.
Centreline of enclosure
400 mm right of centreline
55 mm from base of enclosure
378 mm left of centreline
580 mm from base of enclosure plus or minus 25mm
Ensure the penetration points are marked accurately as this is critical for successful
appliance installation.
The penetration for the flue pipe only needs to be made for ‘Direct’ flue installations, where
the flue terminal is located directly to the rear of the appliance.
If no flue pipe penetration is required the markings are still useful for indicating the correct
position of the flue transition within the enclosure for extended horizontal flue applications.
