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.
• For Domesc Hot Water systems, if you
install the boiler in an area that is known to
have hard water or that causes scale build-
up, the water must be treated and may
require a more frequent ushing schedule.
Scale build-up is caused by hard water and
can be accelerated if the boiler is set at a
high temperature. Rinnai oers
Southeastern Filtraon’s “ScaleCuer Water
Condioning System” that oers superior
lime scale prevenon and corrosion control
by feeding a blend of control compounds
into the cold water supply.
• 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.
IMPORTANT
Replacement of components due to
water quality damage is not covered by
the warranty.
