Determine Installation Location - Rinnai REU-VA1320WF-US Operation And Installation Manual

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, and electrical connection 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.

Environment
Air surrounding the water heater 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 such locations be avoided.
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 INSTALLATION:

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.

Chemicals that are corrosive in nature should not
be stored or used near the water heater.
Damage and repair due to corrosive compounds in
the air is not covered by warranty.
