Whether upgrading your existing system or adding a new pool or spa to your home, the 406 ASME pool heater offers you flexible installation solutions. Thanks to a brilliant low-profile design, corrosion resistant cabinet made of galvanized metal, copper fin tube heat exchanger, and a bevy of advanced-engineered materials, enjoying your heater year-round is a breeze. The Digital ASME also comes equipped with ProTek Shield, Raypak's new cutting-edge module that protects the heat exchanger and extends the life of your Raypak.
The 406 Digital ASME Bronze Cupro-Nickel 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
No need for fans to combat drafting problems under normal conditions. This B-R406A-EN-X ASME pool 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.
406 ASME Controls
These 406 ASME Cupro-Nickel pool heaters are available with digital electronic ignition. 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.
All-Copper-Fin-Tube Heat Exchanger
The 406 ASME 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.
Condensation Protection
The Unitherm Governor inside the 406 ASME 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 406 ASME Bronze 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 406 ASME 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
A ceramic fiber combustion box keeps your heater running efficiently while keeping the outside 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 Raypak 406 ASME heaters consistently achieve the highest efficiency ratings. They exceed all federal and state standards.
