Consideraon of care for your boiler should
include evaluaon of water quality.
• The water must be potable, free of
corrosive chemicals, sand, dirt, or other
contaminants.
• It is up to the installer to ensure the
water does not contain corrosive
chemicals or elements that can aect or
damage the boiler.
• Water that contains chemicals
exceeding the levels below can damage
the boiler.

When choosing an installaon locaon, you
must ensure that clearances will be met and
that the vent length will be within required
limits. Consider the installaon
environment, water quality, and need for
freeze protecon. Requirements for the gas
line, water lines, electrical connecon, and
condensate disposal can be found in their
respecve installaon secons in this
manual.
This secon provides informaon on the
importance of water quality to the Rinnai
Condensing Boiler. The informaon is
intended to serve as general guidelines only
and is not a complete list of water quality
guidelines.
• Unsuitable heang system water can
cause the formaon of scale or sludge,
which aects system eciency. It can
also cause corrosion and reduce life of
the heat exchanger.
• Never use water that has been treated
by a reverse osmosis, deionized, or
dislled water to soen the water to
ll the heang system.
• Oxygen permeable or rubber tubing is
not permied in the heang system
unless it is separated from the boiler by
a plate heat exchanger.
• Thoroughly ush the system prior to
lling. While ushing, isolate the boiler.
• Do not introduce any system cleaner
into the boiler. Flush the system
thoroughly to remove all system
cleaner before lling the boiler with
water.
• When freeze protecon of the heang
system is desired, only use Rinnai-
approved anfreezes. The allowed
maximum concentraon is 40%.
• Reference secon “14.1 Approved
Cleaners, Inhibitors and Anfreezes” in
the Appendix for an approved list of
system cleaners, inhibitors, and
anfreezes.

Replacement of components due to
water quality damage is not covered by
the warranty.
