Consideration of care for your boiler should
include evaluation 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 affect or
damage the boiler.
•
Water that contains chemicals
exceeding the levels below can damage
the boiler.

When choosing an installation location, you
must ensure that clearances will be met and
that the vent length will be within required
limits. Consider the installation
environment, water quality, and need for
freeze protection. Requirements for the gas
line, water lines, electrical connection, and
condensate disposal can be found in their
respective installation sections in this
manual.
This section provides information on the
importance of water quality to the Rinnai
Condensing Boiler. The information is
intended to serve as general guidelines only
and is not a complete list of water quality
guidelines.
•
Unsuitable heating system water can cause
the formation of scale or sludge, which
affects system efficiency. 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 distilled
water to soften the water to fill the heating
system.
•
For Domestic 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 flushing schedule.
Scale build
- up is caused by hard water and
can be accelerated if the boiler is set at a
high temperature. Rinnai offers
Southeastern Filtration
’ s “ ScaleCutter Water
Conditioning System ” that offers superior
lime scale prevention and corrosion control
by feeding a blend of control compounds
into the cold water supply.
•
Oxygen permeable or rubber tubing is not
permitted in the heating system unless it is
separated from the boiler by a plate heat
exchanger. The boiler warranty may be
voided if connected directly to CH systems
that include this tubing.
•
Thoroughly flush the system prior to filling.
While flushing, isolate the boiler.
•
Do not introduce any system cleaner into
the boiler. Flush the system thoroughly to
remove all system cleaner before filling the
boiler with water.
•
When freeze protection of the heating
system is desired, only use Rinnai
- approved
antifreezes. The allowed maximum
concentration is 50%.
•
Reference section “ 14.1 Approved Cleaners,
Inhibitors and Antifreezes ” in the Appendix
for an approved list of system cleaners,
inhibitors, and antifreezes.
IMPORTANT
Replacement of components due to
water quality damage is not covered by
the warranty.
