DO NOT
store or use gasoline or other
flammable vapors and liquids in the vicinity

DO NOT use any phone in your
building.

Immediately call your gas supplier from

•
If you install this water heater in an area
that is known to have hard water or that
causes scale build-up the water must be
treated and/or the heat exchanger flushed
regularly. Rinnai provides a “Scale Control
System” that offers superior lime scale pre

vention and corrosion control by feeding a
blend of control compounds into the water
supply. Damage and repair due to corrosive
compounds in the air is not covered by
warranty.
•
Keep the combustion air vent pipe loca
-
tion free of chemicals, such as chlorine or
bleach, that produce fumes. These fumes
can damage components and reduce the
life of your appliance. Damage and repair
due to scale in the heat exchanger is not
covered by warranty.

Always check the water temperature before
entering a shower or bath.
•
DO NOT adjust the parameters unless
specifically instructed to do so.
