Features

Microprocessor-Controlled Thermostat

The Rheem Digital gas heater comes with a microprocessor-based control center. This allows you to set your pool or spa temperature precisely at your preferred setting by simply pressing the up or down temperature control button. The digital display provides a constant readout of your pool or spa water temperature. Just set it, and forget it! Truly simple. If only your VCR were this easy to operate.

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. In the unlikely event that a problem develops the digital display easily points out the problem and the probable cause. It’s like having a service technician built into every heater!

Remote Compatible

The new 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.

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 pressure fluctuations, allowing the heater to 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 reliable and robust ignition system available- an industry proven standard for over 20 years.

Cool Running

The ceramic fiber combustion chamber keeps your heater running efficiently while ensuring the outside jacket stays cool. By using this space-age material, the heater won’t retain residual heat after it is turned off, allowing it to be installed without the need for excessive clearances. This heater is also certified for installation on a combustible surface.

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 it actually protects itself from the things that tend to stifle ordinary pool and spa heaters. It delivers uninterrupted heating performance regardless of falling leaves, wind, airborne 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 solventborne- 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.

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, 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.

Options

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 efficiently transfer heat, 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 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.
