Determine Installation Location; Water Quality - Rinnai REU-VC2528FFUD-US Mode D'emploi

Determine 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 of this manual.

Water Quality

Consideration of care for your water heater should
include evaluation of water quality.
The water must be potable, free of corrosive chemicals,
sand, dirt, or other contaminates. It is up to the
installer to ensure the water does not contain corrosive
chemicals, or elements that can affect or damage the
heat exchanger. Water that contains chemicals
exceeding the levels below affect and damage the heat
exchanger. Replacement of the heat exchanger due to
water quality damage is not covered by the warranty.

Regulations
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.
When scale build-up in the heat exchanger begins to
affect the performance of the water heater, a diagnostic
code "LC#" will display. Flush the heat exchanger to
prevent damage to it. Scale build up is caused by hard
water 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.

Environment
Air surrounding the water heater, venting, and vent
termination(s) is used for combustion and must be free
of any compounds that cause corrosion of internal
components. These include corrosive compounds that
are found in aerosol sprays, detergents, bleaches,
cleaning solvents, oil based paints/ varnishes, and
refrigerants. The air in beauty shops, dry cleaning
stores, photo processing labs, and storage areas for pool
supplies often contains these compounds. Therefore it
is recommended that outdoor models be used for these
locations where possible.
The water heater, venting, and vent termination(s)
should not be installed in any areas where the air may
contain these corrosive compounds. If it is necessary for
a water heater to be located in areas which may contain
corrosive compounds, the following instructions are
strongly recommended.
IMPORTANT CONSIDERATIONS FOR:
Indoor/Internal Water Heaters

DO NOT Install in areas where air for combustion
can be contaminated with chemicals.

Before installation, consider where air has the
ability to travel within the building to the water
heater.

Where possible, install the water heater in a sealed
closet so that it is protected from the potential of
contaminated indoor air.

Chemicals that are corrosive in nature should not
be stored or used near the water heater.
Outdoor/External Water Heaters and Vent
Terminations of Indoor/Internal Water Heaters

Install the water heater as far away as possible
from exhaust vent hoods.

Install as far away as possible from air inlet vents.
Corrosive fumes may be released through these
vents when air is not being brought in through
them.

Chemicals that are corrosive in nature should not
be stored or used near the water heater or vent
termination.
Damage and repair due to corrosive compounds in the
air is not covered by warranty.
