The Raypak Digital 266A is an atmospheric gas heater for pools and spas. Its digital thermostat shows water temperature and status messages on an LCD.

Made for:

• Natural gas only. The propane 266A for the same elevation is a different item number (009225).
• Raypak lists item 009221 for 2,000 to 6,000 ft and item 009847 for 6,000 to 9,000 ft.
• Outdoor installation as shipped, using the stackless top packed with the heater. Indoor installation needs Raypak indoor stack kit 009839 and a vent to the outside.
• Pump flow between 25 and 100 GPM. Above 100 GPM Raypak calls for an external bypass valve.

Details:

• Raypak lists the Digital series at 82% thermal efficiency.
• Natural gas supply pressure 6 in. WC minimum, 10.5 in. WC maximum. Gas connection 3/4 in. NPT.
• A ProTek Shield sacrificial assembly under the inlet connection protects the heat exchanger from galvanic corrosion.
• Electronic intermittent ignition lights the pilot and main burners automatically on a call for heat.
• Digital control with LCD display: pool and spa modes, adjustable setpoint, status and diagnostic messages. Remote-ready for two-wire or three-wire control systems.
• Unitherm Governor (thermostatic mixing valve) and a built-in automatic bypass valve in the inlet/outlet header.
• Power 120 or 240 VAC, single phase, 60 Hz. Draws 4 A at 120 V or 2 A at 240 V. Not for 208 VAC.

• Raypak limited warranty: two years parts and labor, or one year when installed anywhere other than a single-family home.
• Rheem cross-reference: Rheem item 009963, model P-M266A-EN-C #50, is the same heater sold under the Rheem label.
• Ruud cross-reference: Ruud item 009995, model P-D266A-EN-C #50, is the same heater sold under the Ruud label.

Good to know:

• Raypak's rated input applies up to 2,000 ft. Above that the manual reduces input 4% for each 1,000 ft above sea level.
• This is an atmospheric heater, not a Low NOx model. Raypak's Low NOx Digital heaters are the 207A to 407A models, and Raypak notes that some states and localities require Low NOx heaters.
• The ProTek Shield is a wear item. Raypak says to replace it when its weight has dropped to about 40% of the original.
• Salt chlorinators and chemical feeders must be plumbed downstream of the heater. Raypak's water chemistry table allows up to 4,500 ppm salt.
• Gas, venting and electrical work must be done by a qualified installer or service agency and meet local codes. Raypak's warranty applies to heaters installed by a licensed service provider.
