Hydrotherm BM-8073 Pilot Assembly

The Hydrotherm BM-8073 Pilot Assembly is a critical OEM replacement component engineered specifically for liquid propane (LP) boiler systems. As a veteran-grade standing pilot assembly, the BM-8073 ensures consistent ignition and flame monitoring for Hydrotherm gas-fired units. This robust assembly features the LP-Q314ALB pilot burner configuration, designed to provide a stable, high-efficiency pilot flame for reliable main burner ignition. When troubleshooting ignition failures or burner instability, replacing the assembly with this genuine Hydrotherm boiler part is essential for maintaining system safety and performance standards. The LP pilot assembly is precision-manufactured from high-heat resistant alloys to withstand the rigors of atmospheric combustion, preventing premature thermocouple degradation and ensuring precise fuel-to-air mixing. For contractors focusing on HVAC replacement parts, this assembly simplifies the maintenance of legacy Hydrotherm equipment by matching exact factory specifications for mounting and gas flow.

• Precise LP Calibration: Specifically jetted and configured for liquid propane systems, preventing the soot buildup common with incorrect orifice sizing.
• OEM Compatibility: Drops directly into Hydrotherm boiler configurations using the BM-8073 MPN, ensuring correct alignment with the main burner.
• Enhanced System Reliability: Features a durable standing pilot design that provides consistent flame sensing for uninterupted heating cycles.
• Durable Construction: Built with high-grade metal components to resist corrosion and thermal stress in high-temperature combustion chambers.

• Is this pilot assembly compatible with Natural Gas? No, the BM-8073 is specifically designed for LP (Liquid Propane) applications. For natural gas units, the BM-8072 is the correct alternative.
• What causes a pilot flame to frequently go out? Frequent outages are often caused by a faulty thermocouple or a clogged pilot orifice; replacing the entire pilot assembly restores reliable operation.
• Does this include the pilot tubing? This part is the assembly itself; ensure your existing pilot line and fittings are clear of debris before reconnecting.
