heater can report how long it has run and
how many times it has fired. This is valu­able feedback for the service professional.

On Board Voltmeter

The Raypak Digital monitors the low volt­age electrical supply. This helps ensure
the heater is wired properly during instal-

lation. The 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 Raypak.

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 can shorten the life of a heater. Raypak engineered the Unitherm
Governor specifically for
reduce condensation. The built-in automatic bypass helps prevent scaling and erosion by balancing
the flow going into the heat exchanger.

The Raypak Digital, with polymer headers, is equipped with an integral copper finned-tube heat
exchanger and stainless steel tube sheets. Even the smallest details such a
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.

Burners

Stainless Steel Burners

Burner design is a critical component in any gas heater. The stainless steel burner system used in the
Raypak Digital is inherently forgiving and extremely robust.

Fan-Assisted Combustion

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 outperforms all others during cold starts and provides longer component life.

Pilot Ignition

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 30 years.

The right tube for the right application

Copper Fin Tube - Residential

The Raypak 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 the first choice for pool and spa
heat exchanger construction. Pure copper has stood the test of time
as the industry standard for efficiency, quality and product life.

ASME Copper Fin Tube - Commercial

Raypak Digital ASME is designed specifically to meet

The
State and local code requirements for public pools and commercial
applications. This heater is equipped with a thicker walled fin tube
allowing it to meet the ASME certification requirements.

Cupro-Nickel Fin Tube - Commercial Specialty

Raypak ASME Digital heaters can be ordered with cupro-nickel fin
tube heat exchangers for added protection against aggressive water
chemistry. Although rare, there are certain applications, like health
club spa’s, where copper is just not the best choice. Cupro-nickel
offers superior tolerance to bad and fluctuating water chemistry,
thanks to a harder surface and a thicker walled fin tube.

On-site state inspectors

ASME

ASME

The Raypak Digital heater is also available in an
optional ASME version. Raypak has state inspectors
on-site daily performing certifications for our pool
heater and commercial boiler production that require
ASME. Being in the boiler business for over 60 years
truly makes Raypak the leader for your commercial
needs. Why ASME? Most local codes require that pub­lic pools, pools that are in condominiums, apartments,
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 standards must
perform to a set of specifications as determined by ASME, specifically in relation to the
operating water pressure the appliance can handle. Each and ever
er that goes into a Raypak heater is certified by a state inspector to make sure it complies
with all ASME codes for pool heaters.

Glass-Lined Cast Iron Headers

Raypak has applied its 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 th
tion tests is it approved for use in an ASME unit.

Optional D-2 Power Vent

D-2 Power Vent

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 and prevents excessive condensate production in the vent. All

Using the Raypak-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
