RayPak Low NOx Pool Heater Features

Digital Control
Microprocessor-controlled Thermostat
The Raypak Digital gas heater is equipped with a microprocessor-based control center. This control allows you to set your pool or spa temprature precisely at your preferred setting just by pressing an up or down temprature control button. The digital display gives you a constant readout of your water temperature.
Self-Diagnostic		Remote-Compatible
Troubleshooting a Raypak gas heater has never been easier. The Raypak 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 developes, the digital display easily points out the problem and the probable cause. It's like having a service technician built into every Raypak Digital heater.		The Raypak Digital is compatible with most major brand pool control and remote systems on the market today. Any two- or three-wire remote can connect to the Raypak Digital heater and be integrated into the pool control system of your choice.
Heat Exchanger
Condensation-Free Operation
Both water temperature and flow rate inside the heater are controlled to help eliminate condensation, sooting and scale buildup that cab shorten the life of a heater. Raypak engineered the Unitherm Govenor Specifically for pool heater application, regulating low-temperature incoming water to help reduce condensation. For over 30 years, Raypak has led the industry, setting the standard for condensation protection.
Rust-Free Waterways
The Raypak Digital, with polymer headers, is equipped with an integral copper finned-tube heat exchanger and stainless steel tube sheets. This unique construction guarantees rust-free operation, especially important when heating spas and smaller pools. Even the smallest details such as the studs and nuts are made out of stainless steel. the Payoff? A heater that will last years after yearsand can easily be services if the need should ever arise.
Burners
Stailess Steel Burners
Burner design is a critical component in any gas heater. The stailess steel burner system used in the Raypak 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.
Fan-Assisted Combustion		Pilot Ignition
Not all low NOx heaters are made the same. The Raypak Low NOx design uses a fan to provide cool, controlled combustion air to the burners. Other brands use a fan to pull hot flue gases through the heater. The RAypak design allows the heater to outperform all others during cold starts and provide longer components life.		The Raypak 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.
Copper Fin Tube - (Standard)
The Raypak Digital is built with the highest quality integral copper fin tube available. Copper is well known for it's ability to efficiently transfer heat, and is an excellent choice for pool and spa heater exchangers, where the water chemistry is properly maintained.
ASME Copper Fin tube - (Optional)
The Raypak Digital ASME gas heater is equipped with .062" wall integral copper finned tubes. This tubing is approximately 50% larger in wall thickness than standard tubing, providing additional resistance to wear from chemical corrosion. The Raypak Digital heater is also available in an optional ASME version. Raypak has inspectors on-site daily performing certifications for our pool heater and commercial boiler production that may require ASME. Being in the boiler business for over 50 yearstruly ,akes Raypak the leader for your commercial needs. Why ASME? Most local codes require that public pools, pools that are in condominiums, appartments, or other commercial applications, be ASME certified. ASME stands for American Society of Mechanical Engineers, a non-profit group which sets many industrial and manufacturing standards. A pool heater that is made to ASME standard must perform to a set of specifications as determined by ASME, specifically in relation to the operating water pressure the application can handle. Each and every ASME heat exchanger that goes into RAypak heater is certified by a state inspector to make sure it complies with ASME codes for pool heaters.
Glass-Lined Cast Iron Headers
Raypak has applied it's years of commercial boiler experience to the design of the cast iron glass-lined header. A metal header design allows for the higher working pressures required by ASME. Only after the material meets the stress anaysis and metal composition tests is it approved for use in an ASME unit
Cupro-Nickel Fin Tube - (Optional)
Raypak 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 offers superior tolerance to bad water chemistry and increases erosion protection, thanks to a harder surface and wall that is approximately 50% thicker than our standard copper fin tube. When you're 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.

The D-2 Power Vent (optional)
	Sometimes, equipment rooms or unusual venting configurations require the use of a power vent. Being the heater experts, we have the D2 Power Vent assembled i a category III mechanical draft venting system that operates under a positive static pressure and prevents excessive condensate production in the vent. All sizes are capable of relieving the flue gases up to a maximum of 100 equivalent feet of vent length. All models have a standard 4" diameter exhaust connection. Using the Raypak-supplied adjustable 90 degree elbow, the flue gases may be discharged in any direction (see the D-2 Power Vent manual for details). The D-2 Power Vent is also dual-voltage capable (120/240 volts) and engineered for long life and smooth operation.
