Raypak Millivolt 336K BTU Natural Gas Pool Heater - Copper - P-R336A-MN-C | 009194

The Raypak P-R336A-MN-C delivers a robust 336,000 BTU output using a classic Millivolt ignition system. Because it utilizes a standing pilot light and thermopile to generate its own small electrical current, this heater requires absolutely no external electricity to operate. It is the ideal choice for remote equipment pads, areas prone to power outages, or older pool setups where running new electrical conduit is impractical.

The 009194 model provides the rapid heat-up times needed for large residential pools while retaining the simple, mechanical reliability that has made Raypak a trusted name for decades. Equipped with a standard copper heat exchanger, it delivers consistent and efficient everyday performance.

Features

No Electricity Required: The Millivolt system generates its own power directly from the heat of the pilot flame. This makes it completely immune to power surges and grid outages, ensuring your pool stays warm even during severe weather or rolling blackouts.

Robust 336,000 BTU Power: Providing massive thermal lift, this unit delivers rapid temperature gains for large residential pools and attached spas, ensuring you get the fast heating you need without relying on a digital connection.

Simple Analog Dial Control: Features a straightforward mechanical thermostat. There are no digital screens to fail or complex menus to navigate; just turn the dial to your desired temperature for a true set-it-and-forget-it experience.

Standard Copper Heat Exchanger: Built with high-quality integral copper fin tubes, this heat exchanger provides maximum heat transfer and 82% thermal efficiency. The single-piece header design ensures smooth water flow and minimizes the risk of internal leaks.

PolyFlo Integrated Bypass: Raypak’s patented bypass design balances the water flow through the heat exchanger automatically. This prevents condensation and scale buildup, protecting the heater's internal components from premature wear.

ProTek Shield Technology: Includes a specialized, replaceable module designed to protect the heat exchanger from the damaging effects of galvanic corrosion (electrolysis), a critical feature for extending the life of the unit in modern pool environments.

Non-Corrosive Cabinet Construction: The unit is housed in a polyester-coated, galvanized steel cabinet built to resist rust and UV fading. Its wind-resistant design ensures the standing pilot and burner stay functional even in exposed or rural outdoor environments.

Notes

Professional Setup Required: Because this high-capacity unit utilizes a standing pilot and a massive gas draw, it must be installed by a licensed HVAC or pool professional. Proper gas line sizing (typically 1.25 inches) and adequate venting are critical.
