Product Overview
The Pentair 471204 Pilot Assembly is a service replacement part used in compatible natural gas IID ignition heater systems. It is most commonly tied to MiniMax Plus and PowerMax heaters, along with related commercial MiniMax applications that use the same pilot style. Because the pilot assembly is a key part of the heater ignition sequence, its condition directly affects startup reliability and overall burner operation during a call for heat.
This part is best suited for repair situations where the heater remains otherwise serviceable but the original pilot assembly has become worn, damaged, or unreliable. The natural gas configuration and IID application are both important to correct fitment, so it should be matched carefully to the heater model and ignition type. For service professionals maintaining compatible Pentair heater platforms, the 471204 fills an important role in restoring dependable ignition performance and normal heater operation.
