Wall Penetrations - Rinnai RHFE-750ETR Installation Manual

It is critical that any wall penetrations are located correctly.
The enclosure dimensions specified are critical to the successful installation of this appliance
and MUST BE strictly adhered to.
CAUTION
Ensure there are no wall studs, noggins, wiring or other obstruction within the wall cavity where
the flue is proposed to penetrate.
Ensure the location of the flue terminal can comply with the requirements of AS5601. Figure 5.3
from AS5601-2004 and additional information is shown on page 2.
Especially relevant is the requirement to have a minimum of 300mm clearance between the flue
terminal and the finished ground level. It is not permissible to excavate a hole to obtain the
required 300mm clearance, unless there is sufficient drainage provision.
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' and 'Direct Extended' 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 flue exhaust connection of 'Sideways', 'External Wall', 'Internal Wall' and 'Under Floor'
flue applications.
When creating penetrations for flue system installations other than 'Direct' and 'Direct
Extended' the minimum diameter required for the wall penetration of PVC external pipes is 80mm.
IMPORTANT
On all 'Sideways' and 'Under Floor' flue applications, allow for a continuous 2° fall from the
heater connection point to the wall terminal.
