• PolyTuf Textured Powder Coating
The Rheem 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 supe-
rior rust prevention and years of durable service.
• Wind-Resistant Design
No need for fans to combat drafting problems. This heater is designed to draft naturally in
outdoor installations with its exclusive low-profile design. It is so thoughtfully and careful-
ly 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.
•Brass Headers
Brass headers prevent rust stains from harming your pool or spa’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.
•1-1/2” Water Connections
Supplied with every Rheem 055 heater is a set of 1-1/2" flange connections to make your
installation secure and effortless.
•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
Aceramic fiber combustion box keeps your heater running efficiently while keeping the out-
side jacket 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 use of costly metal heat sinks.
•Fuel-Efficient
Energy-smart Rheem heaters consistently achieve the highest efficiency ratings. They
exceed all federal and state standards.
Electronic ignition models only
•Electronic Ignition
Rheem Versa heaters come standardwith intermittent spark ignition pilot safety controls.
What this means is that the pilot only comes on when thereis a call for heat. This provides
an energy-efficient way to control your heater’s gas usage by eliminating the need for a con-
tinuous pilot.
•Dual Voltage 120/240v
The Rheem Versa electronic heater can easily be hooked up to 120/240v power. The heater
comes factorywired for 240v, but can be easily converted to 120v. No other small heater
offers you this much flexibility.
Millivolt models only
•Mechanical Thermostat
The Rheem millivolt gas heater comes with one mechanical thermostat. This control allows
you to set your pool or spa temperature precisely at your favorite setting.
• Millivolt Controls
No power source is required for the Rheem Millivolt heater. All operating electricity is sup-
plied by the pilot thermocouple.
Quality assurance
•ISO 9001
We are proud to be an ISO 9001 registered manufacturing plant. It’s one more reason why
Rheem is number one in the heater industry today.
•End-of-Line Test
Every Rheem 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 trou-
ble-free operation.
•CSA-Certified
All of Rheem’s gas pool heaters are CSA-certified and are tested by CSA to the ANSI Z21.56
standard.
