Description
The Lochinvar & A.O. Smith BNR3502 Burner W/Barbed Fitting is a gas-fired assembly that generates thermal energy within a boiler or similar fuel-fired unit. It directs the incoming fuel-air mixture toward the ignition zone, where combustion produces heat for water heating. The barbed fitting provides a connection point for tubing associated with fuel delivery or control operations, depending on the unit configuration. Within the firing chamber, the burner works alongside ignition and gas-regulation elements to establish the required flame pattern on HVAC systems. Correct placement allows the mixture to enter the firing zone in a controlled manner and maintain the intended path.
