Product Overview
Heat large residential pools and spas quickly with the Pentair MasterTemp 400 Natural Gas Heater. Part number 460736 delivers 400,000 BTU of heating power in a compact cabinet designed for dependable performance, efficient operation, and convenient equipment-pad installation.
The MasterTemp uses an induced-draft combustion system that carefully manages the air-and-gas mixture for reliable heating. Its hot-surface ignition system eliminates the need for a standing pilot, helping reduce wasted fuel while providing automatic electronic startup.
A digital temperature controller gives pool owners convenient access to temperature settings and operating information. Built-in diagnostic indicators help qualified service technicians identify operating problems more efficiently.
The heater connects directly to compatible 2-inch Schedule 40 PVC plumbing and can operate from either 120V or 240V electrical service when configured according to Pentair’s installation instructions.
