Copper Fin Tube
The 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.
Cupro-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 chemistry and is more resistant to erosion, thanks to
a much harder surface and a wall that is approximately 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 Capable
The 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). The D-2 Power Vent is also dual-volt-
age capable (120/240 volt) and engineered for long life and
smooth operation.
