Lochinvar Pool Heater Flame Sensors

Overview

The LOCHINVAR L100165931 is a flame sensor with gasket designed for use in commercial pool heating systems. The flame sensor monitors burner operation by detecting the presence of a flame through ionization current, providing a signal to the control board that confirms ignition. If the sensor fails to detect a flame within the required trial-for-ignition period, the control will initiate a lockout. This part includes the mating gasket for a sealed installation. It is typically installed and serviced by licensed HVAC technicians or commercial pool equipment technicians familiar with hydronic heating systems. This flame sensor is specified for use with the KnightXL AQUAS XP 602 to 802 commercial pool heater series. These are high-capacity commercial pool heaters commonly installed in natatoriums, hotel pools, aquatic centers, and similar facilities. The heater range covered spans the 602 through 802 MBH input models within that product family. Technicians servicing units in this range experiencing nuisance lockouts, flame-sensing faults, or ignition failures should evaluate this sensor as a replacement candidate.
