Condensation-Free Operation
Both water temperature and flow rate inside
the heater are controlled to help eliminate
condensation, sooting and scale build-
up that can shorten the life of a heater.
Rheem engineered the Unitherm
Governor specifically for pool and
spa heater applications, regulating
low temperature incoming water
to help reduce condensation.
Rust-Free Waterways
The Rheem Digital is equipped
with polymer headers and an
integral copper fin tube heat
exchanger built with stainless
steel tube sheets. This ensures
rust-free performance, which is
especially important when heating
spas. Even the smallest details, such
as the studs and nuts, are made out of
stainless steel. The payoff? A heater that will
last year after year and can easily be serviced
if the need should ever arise.

Wind-Resistant Design
Performance and reliability are enhanced by the
“ pagoda top,” designed to keep the Rheem
Digital operating even in windy conditions. No
need for fans to combat drafting problems.
This heater is engineered to draft naturally
in outdoor installations with its exclusive
low-profile design. It is so thoughtfully and
carefully constructed that it actually pro-
tects itself from the things that tend to sti-
fle ordinary pool and spa heaters. It deliv-
ers uninterrupted heating performance
regardless of falling leaves, wind, air-
borne debris, rain, downdrafts, updrafts,
sleet, snow, etc
.
PolyTuf Textured Powder Coating
The Rheem Digital has a polyester-coated, non-
corrosive cabinet that is more durable than solvent-
borne and waterborne-coated metal cabinets. Every
piece of sheet metal goes through a 7-stage wash system,
making certain the powder paint has a perfect bond. Underneath the tough, yet beautiful finish, you
will find galvanized metal that offers superior rust prevention for years of durable service.
Microprocessor-Controlled Thermostat
The Rheem Digital gas heater
is equipped with a micro-
processor-based control. This
control allows you to set your
pool and spa temperature precisely at your preferred set-
ting just by pressing an up or down temperature control
button. The digital display tells
you when the water is being
heated and notifies you when
your target temperature has
been reached.
Self-Diagnostic
Troubleshooting a Rheem gas heater has never been easier. The Rheem Digital has
on-board diagnostic controls that let the user and the service professional know what
is going on with the heater at all times. The display uses
real English, with no cryptic codes to decipher.
Remote-Compatible
The Rheem Digital is compatible with most major pool control and remote systems
on the market today. Any two- or three-wire remote can connect to the Rheem Digital
and be integrated into the pool control system of your choice. The display clearly
shows the heater is under control of a remote system.
Run Time and Cycle Meter
Yet another industry first, the Rheem pool heater can report how long it has run and
how many times it has fired. This is valuable feedback for the service professional.
Multi-unit installations can monitor the run time of each unit and balance out the duty
load, thus avoiding over working one individual heater.
Flame Strength Indicator
Rheem leads the way with the first control in the pool industry to monitor and meas-
ure the pilot flame signal. Known for our high quality, leading edge commercial boil-
ers, it just made sense for Rheem to use this existing commercial technology on our
residential pool heaters. Rheem also uses this function on the end of line test, mak-
ing sure every heater leaves with a robust flame signal.
On Board Voltmeter
The Rheem Digital monitors the low voltage electrical supply. This helps ensure the
heater is wired properly during installation. The heater will also let you know if the
voltage has dropped too low to function properly. No
other pool heater takes care of you like a Rheem.
Stainless Steel Burners
Burner design is a critical component in any gas heater. The stainless steel
burner system used in the Rheem Digital is inherently forgiving and
extremely robust. The burner is self-adjusting to compensate for gas pres-
sure fluctuations, meaning the heater will always burn clean and safe.
Smooth Light Off
The soft-opening gas valve ensures smooth turn-on; no “ Hard Light”
to worry about. Easily removable burner tray and pilot assembly make
service and maintenance a simple task.
Pilot Ignition
The Rheem Digital use a spark-to-pilot ignition system. This is the most reli-
able and robust ignition system available– an industry proven standard for
over 30 years.
