Lochinvar L100165920 Pilot Ignitor with Gasket

Product Description

The LOCHINVAR L100165920 is a pilot ignitor with gasket designed as a direct OEM-style replacement for Lochinvar pool and spa heater units. The ignitor initiates combustion by lighting the pilot flame, which in turn proves the burner circuit and allows the main gas valve to open. Licensed HVAC technicians and pool heater service professionals install this component during routine ignition system service or when diagnosing a no-heat or pilot outage condition. The included gasket provides a proper seal at the mounting point, preventing combustion gas migration. The part measures 5.15 inches in length, 1.4 inches in width, and 0.65 inches in height.

This pilot ignitor is suited for residential and commercial pool and spa heating applications using Lochinvar gas-fired heater units. Compatible series include the SB, AW, XP, KB, and XLP product lines across multiple input ratings. Typical installation occurs during a pilot assembly replacement or combustion system overhaul on Lochinvar pool heaters in the 600 to 1500 range. The replacement gasket included with the assembly eliminates the need to source a separate seal, making this a complete service kit for the pilot section.
