A. O. Smith Master-Fit commercial gas water heaters have always provided
maximum installation flexibility for both new construction and replacement
applications. Now, Master-Fit offers The Eliminator for automatic self-cleaning
protection against build-up of lime and other sediments.
As deposits of lime and other sediments accumulate inside the tank, they form
a barrier between the burner and the water, concentrating heat around
the critical weld areas. The result is reduced energy efficiency, higher
operating costs, and greater risk of premature tank leaks.
Nothing protects like it, and nobody
offers it but A. O. Smith. PermaGlas
Ultra Coat is an exclusive “slush coat”
process that heat-bonds glass to each
tank’s inner surface after all connections
and seams have been welded. Because
it’s a slush coating process instead of a
spray-on coating, PermaGlas Ultra Coat
covers and protects better.
And because A. O. Smith PermaGlas
Ultra Coat is applied after the tank is
welded, there is no chance of “weld
burn” that can burn away normal glass
lining and expose bare steel to water.

Glass Coating
The Eliminator directs incoming cold water under
pressure to sweep the bottom of the tank to keep
sediment moving so it doesn’t accumulate.
With The Eliminator, every Master-Fit water heater
can be expected to maintain its rated efficiency
longer and deliver reliable service year after year.

PermaGlas Ultra Coat provides protection for
the tank’s top, bottom, and outer shell and
all weld seams.
All welds completed prior
to PermaGlas Ultra Coat.
Once tanks are filled
with PermaGlas, they
are rotated (computer
controlled ) for precise,
even coating.
Technician removes hand-
hole clean-out to prepare
it for the next step.
Tanks are then rotated
further, allowing the
excess PermaGlas to
drain from the tank.
After pre-drying in 200ºF
ovens, the tanks are then
fired to 1,600ºF, fusing the
PermaGlas to the steel tank.
