Features:

Raypak's Low Emissions units use combustion control to minimize levels of nitrogen oxides (NOx). These units meet emissions standards in all Low NOx areas, from Los Angeles (SCAQMD rule 1146.2 certified) to the San Joaquin Valley (SJAPCD rule 4308) and any other areas applying the stringent SCAQMD standard -- the "gold standard" of emissions regulations -- to pool heaters.

Available for natural gas only.

PolyTuf Textured Powder Coating
The Raypak gas heater has a polyester-coated,non-corrosive cabinet tha tis 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.
Digital Controls
The digital controls provide simple setup, simple programming, and easy-to-understand diagnostics. The unit only generates a pilot when needed.
Bronze Headers
Rugged bronze 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.
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 heaters consistently achieve the highest efficiency ratings. They exceed all federal and state standards.
