The Raypak Digital 266A is an atmospheric gas heater for pools and spas. This propane version has a digital thermostat with an LCD display.

Made for

• Fuel: propane only. The natural gas 266A for the same elevation is a different item number (009217).

• 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.

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.
• Propane is heavier than air and can collect in low or confined areas; Raypak calls for extra care when lighting propane 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.
