Environment; Clearances From Appliance; Attachment Of The Water Heater - Rinnai RV53i Operation And Installation Manual

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, deter-
gents, bleaches, cleaning solvents, oil based paints/ varnish-
es, and refrigerants. The air in beauty shops, dry cleaning
stores, photo processing labs, and storage areas for pool sup-
plies often contains these compounds. Therefore Rinnai rec-
ommends 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 cor-
rosive 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.

Attachment of the Water Heater

1. Identify the installation location and confirm that the
installation will meet all required clearances.
2. Securely attach the water heater to the wall using any of the
holes in the wall installation brackets which are at the top
and bottom of the water heater. Ensure that the attachment
strength is sufficient to support the weight. Refer to the
weight of the water heater in the Specifications section.

RV53i & RV53e Operation and Installation Manual

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 clos-
et so that it is protected from the potential of contaminat-
ed 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. Cor-
rosive 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.
