Pentair | 471291 | Propane Gas Millivolt Pilot Assembly

The Pentair 471291 Propane Gas Millivolt Pilot Assembly is a replacement ignition component designed for compatible pool and spa heater applications that use a millivolt pilot system and propane fuel. This assembly supports heater startup by providing the pilot flame used in the ignition process, making it an important service part when the original pilot assembly becomes worn, damaged, or no longer functions correctly.

Key Features

• Replacement propane gas millivolt pilot assembly is designed for compatible heater systems that use a millivolt ignition configuration.
• This component supports the pilot ignition process by providing the pilot flame source used during normal heater startup.
• Propane gas configuration is intended for compatible LP heater applications and should be matched carefully to the correct fuel type.
• Intended for maintenance and repair when the original pilot assembly becomes worn, damaged, clogged, or fails to ignite properly.
• OEM replacement design helps maintain fit and function within the original heater ignition system layout.
• Proper pilot assembly performance is important to dependable ignition, stable burner startup, and normal heater operation.
• Targeted replacement format allows service of the pilot ignition area without replacing larger heater control or burner components.
• Durable service-part construction is suited for routine pool and spa heater maintenance in outdoor equipment environments.

Product Overview

The Pentair 471291 Propane Gas Millivolt Pilot Assembly is a service replacement part used in compatible heater ignition systems that rely on a millivolt pilot setup. In this type of heater, the pilot assembly plays a central role in startup by establishing the pilot flame needed for normal ignition operation. Because ignition performance depends on the condition of the pilot components, a worn or damaged pilot assembly can lead to unreliable startup, interrupted heating cycles, or complete ignition failure.

This part is best suited for repair situations where the heater remains otherwise serviceable but the original pilot assembly needs replacement. Since pilot assemblies must match the correct ignition type and fuel type, the millivolt configuration and propane gas application are both important to verify before installation. For pool and spa service professionals maintaining compatible propane-fired heater systems, the 471291 pilot assembly fills an important role in restoring dependable ignition performance and normal heater operation.
