Raypak lists the propane 406A for the same elevation as item 009227, item 009223 for 2,000 to 6,000 ft and item 009849 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 009841 and a vent to the outside.

• 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. Raypak says to replace it when its weight has dropped to about 40% of the original.
• 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.

• Gas, venting and electrical work must be done by a qualified installer and meet local codes.
