Designation for a Digital heater using natural gas is “EN”.
Prefix “P” is for plastic (polymer) headers; “C” is for cast iron (ASME) headers.
Suffix “X” is for cupro-nickel tubing; “C” is for copper tubing
Example: P-R407A-EN-X = Plastic headers, 407 model size, digital, natural gas, cupro-nickel
For elevations above 5000 feet consult the factory.
Manufactured under Patent No. 3,623,458.
Plastic (polymer) headers cannot be used for installations requiring ASME certification.

Features
All models
Digital Control
• PolyTuf Textured Powder-Coating
The Raypak gas heater 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 and years of durable service.
• Wind-Resistant Design
This heater is designed to draft naturally in outdoor installations with its exclusive
low-profile design. It is so thoughtfully and carefully designed 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. .
• Polymer Headers
Polymer headers prevent rust stains from harming your pool’s surface, giving you
years of trouble-free swimming pleasure.
• All-Copper-Fin-Tube Heat Exchanger
The fin tubes of the heat exchanger are each made from a single piece of extruded
copper. This integral-fin design allows maximum heat transfer to be attained and
maintained. Cupro-nickel is also available as an optional upgrade.
• Stainless Steel Tube Sheet
Stainless steel tube sheets are used on all Raypak heaters with the polymer headers.
This allows for a completely nonferrous waterway, leaving your pool truly rust-free.
• CPVC 2" Water Connections
Standard with every Raypak is a set of 2" slip-fit CPVC water connections to make your
installation secure and effortless.
• Condensation Protection
The Unitherm Governor helps reduce condensation from low inlet water temperatures.
It automatically regulates the water flow to help keep the water temperature in the
heat exchanger above 105°F. Both water temperature and water flow rate are
controlled to eliminate condensation, sooting, and scale build-up that can shorten
heater life.
• High Flow Rates
The Raypak gas heater comes with an automatic bypass built into the header. You'll
find that the heater is capable of handling water flow at a rate up to 125 gpm.
• Burner Tray
Every burner tray is built to last, from the stainless steel burners to the aluminized
metal used in the heat sensitive areas. Innovative design allows for the easy removal
of the tray and burners for servicing.
• Fire Tile
By using this space-age ceramic fiber material the heater won't retain residual heat
after it is turned off, this allows it to be installed without the use of costly metal heat
sinks.
• Fuel-Efficient
Energy-smart Raypak heaters consistently achieve the highest efficiency ratings. They
exceed all federal and state standards.
• Low Emissions
The Raypak Low NOx gas heater complies with the most stringent state and county
emissions laws. NOx emissions are less than 40 nanograms per joule.
• Fan-Assisted Combustion
A fan delivers cool, controlled combustion air to the sealed burners.
• Microprocessor-Controlled Thermostat
The Rheem Digital gas heater features a microprocessor-based control center. This
control allows you to set your pool or spa temperature precisely at your favorite setting
just by pressing the up or down temperature control buttons.
• Self-Diagnostic
On-board diagnostic controls let the user and the service professional know what is
going on with the heater at all times. All information is presented in real English, no
cryptic codes to decipher. In the event that you would ever have a problem with the
heater, the digital display will indicate the source.
• Flame Strength Indicator
A pool industry first! The pilot flame signal is monitored with an easy to read visual
bar display. 4 bars or less indicate a weak signal, letting the service tech know that
the pilot should be checked. 5 bars or more indicate good flame rectification. Every
heater is test fired before packaging, and the flame strength is verified to be strong
before leaving the factory.
• Voltage Monitor
Transformer output power can be monitored by the circuit board. This helps service
techs diagnose issues quicker and more efficiently.
• Cycle Counter and Run Time Monitor
The control captures every cycle of the main gas valve as well as how long it stays
open. This offers valuable and useful feedback to the service tech. By monitoring the
run times on multiple unit installations, the load can be evenly distributed among the
units, preventing excessive wear and tear on one unit.
• Remote-Compatible
Compatible with most major pool control and remote systems on the market today. Any
two-wire or three-wire remote can connect to the heater and be integrated into the
pool control system of your choice.
• Electronic Ignition
Rheem Digital heaters come standard with intermittent spark ignition pilot safety
controls. What this means is that the pilot only comes on when there is a call for heat.
This provides an energy-efficient way to control your heater’s gas usage by eliminating
the need for a continuous pilot.
Quality assurance
• ISO 9001
We are proud to be an ISO 9001 registered manufacturing plant. It’s one more
reason why Raypak is number one in the heater industry today.
• End-of-Line Test
Every Raypak gas pool heater is plumbed and test-fired before it is put in the
carton. This ensures that your heater will work right out of the box and continue
to give you years of trouble-free operation.
• Quality Check Points
The Raypak assembly process includes six final assembly quality check points
that help to ensure that every Raypak gas heater is built correctly, and built to
last.
• CSA-Certified
All of Raypak’s gas pool heaters are CSA-certified and are tested by CSA to the
ANSI Z21.56 standard.
In keeping with its policy of continuous progress and product improvement, Raypak reserves the right to make changes without notice
