Horizontal Obstructions; Sideways Flue Diverter; Multiple Appliance Installations - Rinnai REU-AM2626WDL Operation & Installation Manual

Horizontal Obstructions

AS/NZS 5601 'Gas Installations' stipulates a minimum horizontal clearance of 500 mm between a building structure
and obstruction facing the terminal�
For correct operation of Rinnai external continuous flow water heaters such a building structure MUST 'obstruct'
the full front cover height of the appliance (for appliance dimensions, refer to "Table 1� Appliance Dimensions" on
page 26), or extend vertically above and below the front cover as shown below.
There MUST be NO partial obstructions to the front cover of the appliance or any other parts
of the appliance casing� This will avoid the appliance failing to operate under windy conditions�
IMPORTANT

Sideways Flue Diverter

When a Sideways Flue Diverter is to be fitted the installer MUST also refer to the instructions provided with the
Sideways Flue Diverter and observe all the specific clearances and warnings.
CONTROL BOARD DIPSWITCH SETTING:
The installer MUST follow the Sideways Flue Diverter instructions of the "Commissioning Check
WARNING
List" provided on the front cover of the appliance and the "Commissioning Instructions" located
in the inside the appliance front cover�
When delivered ex-factory ALL the
switches of the control board dipswitch
are set to OFF (left position)�
When a Sideways Flue Diverter is fitted
the installer MUST set switches SW1
and SW3 to ON (right position) ONLY�
Improper setting of the switches will cause the appliance to operate incorrectly�

Multiple Appliance Installations

In reference to Horizontal Terminal Clearances (Extract
from AS/NZS 5601) dimension 'h' on page 18 does
not apply when multiple Rinnai external water heaters
of the same model are installed on the same vertical
face with flue terminals at the same height.
Under these conditions appliances can abut each other
as shown above�
The total gas consumption of all appliances applies
when determining other clearances�
For appliance dimensions, refer to "Table 1� Appliance
Dimensions" on page 26�
