Options THE NEW DEGREE OF COMFORTTM Copper Fin Tube The Rheem Digital is built to last with the highest quality integral 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 chemistry 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 pressure that prevents excessive condensate production in the vent. All sizes are capable of relieving flue gases up to a maximum 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-voltage capable (120/240 volt) and engineered for long life and smooth operation. For dimensions and technical specifications, see catalog number MKG-15-1505.
