Rheem heaters are built with many innovative features. The Model 336 includes the below and more!

• Natural Gas Powered: This unit is powered by natural gas. 
• Energy Level: 300,000 BTUs
• 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 superior 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 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 Rheem gas heaters. This allows for a completely nonferrous waterway, leaving your pool truly rust-free.
• CPVC 2" Water Connections: Standard with every Rheem 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 watertemperatures. 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 Rheem 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.
