Gas Connection - Rinnai Arriva 750 Installation Manual

Gas connection

Gas pipe sizing must consider the gas input to this appliance, as well as other gas
appliances in the premises. The gas supply termination is inside the heater, and enters
from the rear right hand side of the appliance.
To ensure correct positioning
terminate the gas supply so it is
80 mm in from the front face of the
enclosure opening.
Purging gas supply
Foreign materials and debris
such as swarf, filings etc. must
be purged from the gas supply.
Failure to do so may cause damage
to the control valve causing it to
malfunction.
Direct flue wall penetration
requirements
Use the guide pictured to mark
the penetration points for the gas
supply and flue transition locations.
Consideration must be given to
the position of any studs, noggins
or other components of the wall
structure on both sides of the wall.
Mark these measurements
accurately as this is critical to a
successful installation.
The penetration for the flue
transition only needs to be made
for direct flue installations, where
the terminal is to be terminated
directly to the rear of the
appliance.
