Raypak Ruud M406a ASME Propane Heater C-R406A-EP-C 009279

Raypak offers a complete line of gas heaters to fit almost every application. Inside and out, the Raypak is the result of over 50 years experience in the design, engineering and manufacturing of all types of residential and commercial pool, and water heaters. These units meet the ASME pressure vessel requirements demanded by code for commercial installations over 200,000 BTUH and are certified to the ANSI Z21.56 pool heater standard.  So dive in and take a look at the Raypak heater that can meet your exact needs.

Features: 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 power paint has a perfect bond.  Underneath the tough, yet beautiful finish you will galvanized metal that offers superior rust prevention and years of durable service.

Wind-Resistant Design No need for fans to combat drafting problems under normal conditions. 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.

Control Options These units are available with two different control designs to meet your requirement.  They are available with digital electronic ignition, or as a millivolt design. The digital system (pictured) requires external power (120VAC or 240VAC) and generates a pilot only when there is a call for heat.  It provides simple setup and easy programming, as well as easy-to-understand diagnostics and simple connections to remote controls. The millivolt ignition system does not require external power.  It generates its' own current internally, with a small thermocouple driven by the constant pilot.  

Cast-Iron Headers Rugged cast-iron headers with porcelainized waterways provide the strength that tough ASME requirements demand.

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 allow 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 inside the header 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.
