Pentair | 42002-0024S | MasterTemp and Max-E-Therm Heater Stack Flue Sensor
The Pentair 42002-0024S Stack Flue Sensor is a replacement temperature safety component designed for compatible Pentair MasterTemp and Sta-Rite Max-E-Therm pool and spa heaters. This part monitors flue temperature within the heater exhaust system and helps protect the unit by responding when exhaust temperature conditions exceed normal operating limits.
Key Features
• Replacement stack flue sensor is designed for use with compatible Pentair MasterTemp and Sta-Rite Max-E-Therm heater electrical systems.
• This sensor monitors exhaust temperature conditions within the heater stack or flue area during normal operation.
• Proper stack flue sensor function is important to helping protect the heater from excessive exhaust temperature conditions.
• Intended for maintenance and repair when the original sensor becomes worn, damaged, or no longer responds correctly.
• OEM replacement design helps maintain fit and function within the original heater electrical and safety system layout.
• This part is commonly referenced as a stack flue sensor or stack flue service kit for compatible heater platforms.
• Current references note that this version can be used to retrofit the older stack flue switch part number 42002-0009.
• Durable service-part construction is suited for routine pool and spa heater maintenance in outdoor equipment environments.
Product Overview
The Pentair 42002-0024S Stack Flue Sensor is a service replacement part used in the exhaust temperature monitoring system of compatible MasterTemp and Max-E-Therm heaters. Current product references consistently identify this SKU as the stack flue sensor for these heater platforms, and several listings specifically note that it is used in the heater electrical system.
Its primary role is to monitor flue or exhaust temperature so the heater can respond appropriately if temperatures rise beyond the intended operating range. Current reference materials also note that the sensor is located on the exhaust elbow and is intended to prevent flue gas output from exceeding approximately 500°F, making it an important protective component within the heater safety system. Some current listings further note that this part includes instructions for retrofitting the older stack flue switch 42002-0009.
