Raypak Digital 336K Natural Gas Heater

The Raypak 014940 (P-R336A-EN-X) is the cupronickel version of the 336A Digital — a 332,500 BTU natural gas residential pool and spa heater built specifically for saltwater pools and installations where water chemistry runs aggressive. It shares the same proven digital platform as the standard 336A but swaps the copper heat exchanger for cupronickel, giving it significantly better resistance to salt, low pH, and high-demand use.

This model replaces the Raypak 010104. The current replacement model is 014940.

Key Features

• 332,500 BTU natural gas input — electronic spark-to-pilot ignition fires only on call for heat, no standing pilot
• Cupronickel fin tube heat exchanger — harder surface and thicker-walled tubing than standard copper; built for saltwater pools, low pH, and heavy use where copper falls short
• Polymer resin headers with stainless steel tube sheets — fully nonferrous waterway, no rust contamination in pool water
• ProTek Shield module included — sacrificial protection for the heat exchanger, replaceable to extend heater life
• Microprocessor digital controls with self-diagnostics — plain-English display, remote compatible with any 2- or 3-wire system, built-in voltmeter and run-time/cycle meter

If you're running a saltwater chlorinator or your water chemistry is hard to keep balanced, the cupronickel exchanger on the 014940 is worth the upgrade over the standard 009218 — it handles the corrosive load that shortens copper exchanger life.

Professional installation by a licensed contractor is required — and warranty registration must be completed — to receive the full 2-year parts and labor warranty. Rated for elevations 0–2,000 ft. only.
