Microprocessor-Controlled Thermostat
The Raypak X94 Professional gas
eater is equipped with a micro-
h
processor-based control. This control
allows you to set your pool and spa temperature precisely
at your preferred setting just by pressing an up or down
temperature control button. The digital display tells you
when the water is being heated and
notifies you when your target temperature has been reached.
Self-Diagnostic
Troubleshooting a Raypak gas heater
has never been easier. The Raypak
Professional has on-board diagnostic
controls that let the user and the service professional know
what is going on with the heater at all
times. The display uses real English,
with no cryptic codes to decipher.
Remote-Compatible
The Raypak X94 Professional is com-
patible with most major pool controls
and remote systems on the market
today. Any two- or three-wire remote can connect to the
Raypak X94 Professional and be integrated into the pool
control system of your choice. The display clearly shows the
heater is under control of a remote system.
Run Time and Cycle Meter
Another industry first, the Raypak
pool heater can report how long it
has run and how many times it has
fired the main burner. This is valuable feedback for the service professional. Multi-unit installations can monitor the run
time of each unit and balance out the duty load, thus avoiding overworking one individual heater.
Flame Strength Indicator
Raypak leads the way with the first
control in the pool industry to monitor
and measure the flame signal. Known
for our high quality, leading edge commercial boilers, it just
made sense for Raypak to use this existing commercial
technology on our pool heaters. This little tool is a service
tech’s dream. Raypak also uses this function on the end-ofline test, making sure every heater leaves with a strong
flame signal.
On Board Voltmeter
The Raypak digital control is so smart
it can monitor the low voltage electri-
cal supply from the transformer. This
helps eliminate miswiring during installation. It lets the installer know if the unit is wired for 240V when 120V is supplied and vice-versa. 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 and no other pool heater has
this function built in.
Flue Gas Temperature Monitoring
The X94 comes standard with
a built-in flue gas high limit lo-
cated in the flue collector. This
allows you to use PVC, CPVC or Polypro without having to buy any accessories to run the low temp flue
pipe.
Fan Speed - High Altitude Adjustment
High altitude operation can be
dialed in at the job site to max-
imize the combustion flue
gases. The blower fan can safely be fine-tuned
through the digital control. This feature is also helpful
with long intake air ducting or to help reduce fan
noise. The user can adjust the fan speed between
7000rpm and 7500rpm.
Freeze Protection
When freeze protection is enabled (when pump operation
is enabled) the control will
monitor the water temperature. If it falls below 40°F
the pump will turn on for 15 minutes. After 15 minutes
the pump will shut off once the water exceeds 42°F.

MORE CONTROL - LESS HASSLE
The Raypak X94 Professional gas heater is equipped with an enhanced functionality board as seen in the photo below.
This control works in conjunction with the standard ignition control board and offers expanded functionality required
to operate the variable speed fan. In addition to the fan control, the board also allows for a pump time clock function,
pump speed controller, 3-way valve controller, freeze protection and burner modulation control. All programming is
one through the standard control LCD display.
d
Time Clock
With the built-in time clock function you
can program the pump for a 7 day
chedule. It can be set for up to 4 dif-
s
ferent operating periods per day. There is also an option to set
2 different schedules, schedule A and schedule B. A manual
override feature for service or operation outside the schedule
is provided.
Pump Speed Controller
The controller can handle any type of
pump from a single speed, dual speed,
4-speed or variable speed. Variable
speed is handled through a direct PWM signal. The pump can
also be programmed to boost the flow automatically when
there is a call for heat in Pool or Spa mode.
3-Way Valve Controller
3-way water valve control is possible
when pump operation is enabled. The
control allows you to program the suction and return valves to the desired position. There is also an
option to allow a “Valve Change Delay”. This turns the pump
off for 30 seconds to allow the valves to rotate into position
without the pump running.
Rheem EcoNet™Enabled
Introducing EcoNet, the first control that integrates
your heating, cooling and water heating systems.
Now you can enjoy total home comfort at your fingertips, with an advanced control that makes it simple to adjust temperature, set schedules, check
system status and more. It’s smart technology that

Full Burner Control- Industry First
Eco Mode • Turbo Mode • Comfort Mode
Another industry first, the Raypak X94
can adjust the amount of input to the
burner. Turbo mode is standard fullfire operation. Eco Mode is a reduced input rate which can
be used for added energy savings or to reduce short cycling. Comfort Mode is for Spa mode and reduces the
burner input as the water approaches the target temperature. Once the water is within 1.5°F of the set point, the
burner modulates the input rate down to match the heating
load. This feature helps keep the water comfortable and reduces short cycling.

Easy Multiple Unit Nesting
Designed with multiple unit installations in mind, the X94
lends itself to space saving installations. All connections,
except for combustion air, are located on the rear of the
unit for clean installations and easy access to the heater.
The unique angled front control panel allows unobstructed
access to the controls when the units are installed side by
side. Unit is serviceable from the top of the unit and the
two front doors. With such a small footprint and close nesting capability, you can install 3 X94 heaters with just under
1.2 million BTU of input and take up less than 22 square
feet!
Venting Options
The X94 Professional offers the most venting options of
ny gas pool heater on the market today. The unit can be
a
installed with 4” PVC, CPVC, Polypro or stainless steel flue
vent. The heater is equipped with a multiport vent adapter
so no extra parts are required. The heater can also be installed with 4” PVC or metal pipe duct to bring fresh combustion air from outside the equipment room. This is
absolutely the perfect solution when chemicals are stored
in the equipment room.
Optional Condensate
Neutralizer
Raypak also offers a condensate neutralizer that is
performance matched to the
X94. Inexpensive and easy to
install and maintain. All PVC
construction with limestone
rock neutralizer. Raypak
makes larger neutralizers
that can be used on multiple
unit installations. Consult the
factory for sizing.
P/N 015199
Multiple Plumbing
Options
Another industry first from Raypak - 4
possible water connection configurations. Not only do you have righthanded and left-handed options, but
now you have pass-through options as
well. You can place the heater in series
with your equipment plumbing. The
clean, straight piping eliminates or reduces the number of elbows needed,
offering you the lowest possible pressure drop. The X94 Professional comes
with 2 CPVC plug fittings to allow you
full flexibility when installing the unit.
Optional Stainless Steel

THE HEART AND SOUL OF THE RAYPAK X94 PROFESSIONAL
®
AL-6XN
Alloy
Super-Austenitic Stainless Steel Heat Engine
The heat engine on the X94 is made from
a high-end metal alloy blend that was developed over 40 years ago for use with
seawater and brackish water conditions. Used primarily in condensers and heat exchangers on offshore oil platforms and power plants. This special alloy blend is far superior in strength, pitting and
corrosion resistance than other types of stainless. It is also preferred over titanium and other stainless steels when
used in high salt-water applications. Raypak spent over three years developing the perfect heat engine for pool applications. We tested several different types of stainless material and concluded that AL-6XN is far superior to any other
material available. Every part of the heat engine is made from this material including the fire box, heat exchange tubes,
headers and nipples.
AL-6XN®Alloy stainless steel
. This is
So What Does This Mean To You?
Believe it or not, pool water is one of the most corrosive water applications for a heater to operate and survive in. Especially with the popularity of salt chlorine generators, the water continues to challenge the life span of pool heaters.
The X94 is built specifically for this environment and uses all of the best materials available to provide the longest life
for a premium product. No other high efficiency pool heater is built with the advanced alloys and heat engine design
as the Raypak X94. There really isn’t any competition to the Raypak Professional Series.
THE MYSTERY OF ASME UNCOVERED
The Raypak X94 Professional heater comes standard as an ASME certified and stamped unit. 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 in compliance with ASME Section IV.
ASME
stands for
dustrial and manufacturing standards. A pool heater that is made to ASME standards must conform
to a set of specifications as determined by ASME, specifically in relation to the operating water pressure the appliance can handle. Each and every ASME heat exchanger that goes into a Raypak Professional heater is inspected to make sure it complies with the ASME Code for pool heaters.
That’s why Raypak is the only pool heater manufacturer to supply a flow switch, PRV and T&P gauge standard with every
Professional Series gas heater under 400MBTU. We know what it takes to make a unit 50-state ASME compliant right out of
the box. Does your heater company make sure all the little details are taken care of like Raypak does, or do you have to
make another trip to your distributor to get everything you need?
