COMMERCIAL WATER HEATERS
STRENGTH IN NUMBERS
Cyclone Xi water heaters can be installed in manifolded
multiples to serve the highest demand applications in place of
boiler systems. For example, four BTH-500s can be manifolded
to provide total storage of 520 gallons with an input of
2,000,000 BTU.
The Cyclone Xi features power-vent and power direct-vent design, allowing clean uncontaminated
air to be drawn directly into the unit with the flue gas products vented conventionally through the
ceiling or directly through the wall to the outside.

EASIER TO INSTALL
Because installation space today is almost always at a premium, we’ve designed the Cyclone to install in
an absolute minimum of space. The exhaust outlet and fresh air intakes are positioned so the water
heater can be placed either in a corner or against a wall.
ADVANCED GLASS LINING TECHNOLOGY
Exclusive PermaGlas
®
Ultra Coat
™
glass lining protects all Cyclone
water heaters. PermaGlas Ultra Coat provides superior protection for
all inner tank surfaces, as well as for the inside of the heat exchanger,
which would otherwise be vulnerable to corrosion from flue gas
condensate. The innovative helical coil minimizes weld points to
extend tank life.
