Raypak High Altitude Natural Gas Pool Heater 336K BTU, P-R336A-EN-C, 009848, 009972

This is the Raypak digital natural gas pool and spa heater at 336,000 BTU, in the high altitude configuration for installations between 6000 and 9000 feet.

Why altitude matters

Air gets thinner with elevation, and a gas burner set up at sea level does not fire correctly several thousand feet up. The high altitude version is configured for that reduced air density, so the heater runs the way it was designed to at that elevation.

Electronic ignition

Raypak Digital heaters use an intermittent spark ignition pilot safety control. The pilot lights only when there is a call for heat, rather than burning continuously between cycles. It is a design Raypak has run on these heaters for over twenty years.

Digital control

A microprocessor based thermostat takes the setpoint from an up and down button and holds it, while the display gives a constant readout of pool water temperature.

Part numbering

The source lists this heater under more than one number. The listing title gives P-R336A-EN-C 009848, while the part number field gives 009972, listed elsewhere in the same source as P-M336A-EN-C. Confirm the exact model with us before ordering.
