Environment

Air surrounding the water heater is used for

combuson 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

oen contains these compounds. Therefore it is

recommended that such locaons be avoided.

If it is necessary for a water heater to be located in

areas which may contain corrosive compounds, the

following instrucons are strongly recommended.

IMPORTANT CONSIDERATIONS FOR INSTALLATION:

 DO NOT Install in areas where air for combuson

can be contaminated with chemicals.

 Before installaon, 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.

Consideraon of care for your water heater should
