Flueing - Rinnai Arriva Operation And Installation Manual

Flueing - General
For all installations an Rinnai Arriva flue system MUST BE used. Flue system must be
fully assembled and secured in place before the heater is installed.
IMPORTANT
Must be compliant with 'Clearances Required for Flue
Flue terminal
Terminals' from NZS 5261 2003. Flue terminal should be
locations
positioned away from flammable materials.

1 x 90° bend = 1 m of length, for every 90° bend the overall length must
be reduced by 1 m (i.e. with 3 bends maximum flue length is 5 m).
Flue transition for all flueing installations (excluding horizontal direct
flueing) is counted as a 90° bend.
Down rating For all Arriva flueing except direct flueing, the appliance must be down
the appliance rated as per instructions on the data plate. Down rating ensures effective
performance of the fan.
Roof space
Flue is not to terminate under floors or in a roof space.
or underfloor
termination
A condensate trap is required for any vertical flue installations to ensure
Condensate
condensate generated during combustion is trapped and prevented from
entering the chamber.
For horizontal and down and out installations there must be a continuous
fall of at least 2°. This equates to approximately 20 mm per metre to the
termination point to drain condensate. For standard direct flueing the Rinnai
flue kits have an inbuilt 2° fall.
The Arriva must not be flued into natural draft flue cavities or via a
Masonry
chimney.
