Installation Notes
Steam Generators can be typically mounted within 50 ft. of
the bathing area.
Steam Generators should be accessible for service.
Do NOT install near flammable material such as paints,
thinners, gasoline, etc.
Steam generators must NOT be installed outdoors, in
moist, humid areas, in areas prone to freezing, or extreme
heat such as an unventilated attic. To do so will void the
warranty.
