Framing Dimensions - Rinnai Arriva 752 Installation Manual

Framing dimensions

The main points governing location are flueing and warm air distribution. The Rinnai Arriva has
an integrated zero clearance box that isolates the appliance from combustible materials. This
means it can be installed directly into a decorative fireplace constructed from materials such as
wood or plaster.

To ensure the appliance performs correctly, without rattling, it must be installed on a flat
level support base that allows free movement of the appliance. The joists used to support the
appliance off the ground must be capable of supporting a minimum of 1.5 times the weight of
the appliance.
Wheels, located at the rear of the heater, allow the unit to slide in and out of the enclosure for
installation and maintenance.
Installer please note:
Issues caused by 'rattling' fires not installed on a flat level base, as detailed in these
instructions, will not be covered by warranty.
