Condensation-Free O eration
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
he Rheem Digital is equipped
with polymer headers and an
integral copper fin tube heat
exchanger built with stainless
steel tube sheets. his 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. he 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.
his 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
he 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.
Micro rocessor-Controlled Thermostat
he Rheem Digital gas heater
is equipped with a micro-
processor-based control. his
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. he digital display tells
you when the water is being
heated and notifies you when
your target temperature has
been reached.
Self-Diagnostic
roubleshooting a Rheem gas heater has never been easier. he 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. he display uses
real English, with no cryptic codes to decipher.
Remote-Com atible
he 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. he 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. his 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
he Rheem Digital monitors the low voltage electrical supply. his helps ensure the
heater is wired properly during installation. he 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. he stainless steel
burner system used in the Rheem Digital is inherently forgiving and
extremely robust. he burner is self-adjusting to compensate for gas pres-
sure fluctuations, meaning the heater will always burn clean and safe.
Smooth Light Off
he 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
he Rheem Digital use a spark-to-pilot ignition system. his is the most reli-
able and robust ignition system available– an industry proven standard for
over 30 years.

Co er Fin Tube
he Rheem Digital is built to last with the highest quality inte-
gral copper fin tube available. Copper is well known for its
ability to transfer heat efficiently, and is an excellent choice for
pool and spa heater heat exchangers, where the water chem-
istry is properly maintained.
Cu ro-Nickel Fin Tube
Rheem heaters are available with an optional cupro-nickel fin
tube heat exchanger for added protection against aggressive
water chemistry, which has been known to attack copper heat
exchangers and cause premature failure. Cupro-nickel's major
advantage over standard copper is that it’ s more tolerant of
bad water chemistr and is more resistant to erosion, thanks to
a much harder surface and a wall that is approximatel 50%
thicker. When you are unsure of your ability to maintain the
pool or spa water chemistry, a cupro-nickel heat exchanger is
a cost-effective way to protect against premature failure.
D-2 Power Vent
Rheem offers an optional power vent feature. Sometimes,
equipment rooms or unusual venting configurations require
the use of a power vent. Being the heater experts, we have this
option for you when the need may arise.
Through-the-Wall Ca able
he D-2 Power Vent assembly is a Category III mechanical
draft venting system that operates under a positive static pres-
sure that prevents excessive condensate production in the
vent. All sizes are capable of relieving flue gases up to a max-
imum of 100 equivalent feet of vent length. All models have a
standard 4” diameter exhaust connection.
Multi-Position
Using the Rheem-supplied adjustable 90° elbow, the flue
gases may be discharged in any direction (see D-2 Power
Vent manual for details). he D-2 Power Vent is also dual-volt-
age capable (120/240 volt) and engineered for long life and
smooth operation.
