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 instruc-
tions 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 po-
tential 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 Termina-
tions 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.
