Environment
Air surrounding the water heater is used for
combuson 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
oen contains these compounds. Therefore it is
recommended that outdoor models be used for these
locaons where possible.
The water heater 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 instrucons are strongly
recommended.
IMPORTANT CONSIDERATIONS:
• 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.
Damage and repair due to corrosive compounds in
the air is not covered by warranty.
