About This Item
The Pentair Lower Enclosure Insulation (42001-0074S) is the OEM replacement insulation panel for the lower burner enclosure on the MasterTemp and Max-E-Therm series pool heaters.
IMPORTANT: LICENSED TECHNICIAN REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
What It Does
This panel lines the lower section of the heater's outer enclosure, containing heat generated by the burner tray and combustion chamber while shielding the surrounding cabinet and adjacent components from direct heat exposure. Insulation that has become brittle, torn, or compressed can allow excess heat transfer to the cabinet exterior and reduce the heater's overall thermal efficiency.

Poolaroo Pro Tip
Seat this insulation panel fully flush against the enclosure wall with no gaps or overlaps before closing up the cabinet — a poor fit lets heat escape around the panel edges and can shorten the service life of nearby wiring and control components. Because this repair involves opening the heater's burner enclosure, have a licensed pool professional or qualified HVAC technician confirm proper seating and reassembly.
