Bard HVAC 8620-202 Pilot Assembly

The Bard 8620-202 Pilot Assembly is a direct OEM replacement component engineered for the Bard WAG series gas-electric wall-mount units. This assembly is critical for maintaining consistent pilot flame rectification and ensuring reliable ignition cycles in high-demand HVACR applications. Designed for natural gas (NG) configurations, the 8620-202 includes a precision-calibrated pilot burner and a durable thermopile lead suited for millivolt control systems. For technicians performing HVAC preventative maintenance or troubleshooting furnace ignition failure, this assembly provides the exact technical tolerances required by the manufacturer to prevent nuisance lockouts and improper combustion. The integration of high-temperature lead wires ensures long-term resistance to thermal degradation within the heat exchanger cabinet. Replacing a fouled or oxidized pilot with a genuine Bard replacement part restores the millivolt signal integrity, maintaining the system's safety circuit and overall equipment efficiency.

• OEM Precision: Guaranteed compatibility with Bard WAG series equipment, eliminating field-modification risks.
• Signal Reliability: Provides consistent millivolt output to the gas valve for stable pilot flame sensing.
• Refined Combustion: Optimized orifice design maintains the correct pilot flame pattern for swift main burner ignition.
• Durable Construction: Engineered with stainless steel components to withstand high combustion chamber temperatures.

Is the Bard 8620-202 compatible with LP conversion kits?
This specific pilot assembly is configured for natural gas systems; verify orifice sizing and manufacturer documentation before attempting any gas type conversion.

Does this assembly include the pilot tubing?
The 8620-202 typically ships as the pilot burner and sensor assembly; existing 1/4-inch pilot gas lines should be inspected for kinks or clogs during installation.

What is the common cause of pilot failure in WAG units?
Carbon buildup on the thermocouple or pilot head is frequently caused by poor secondary air circulation or incorrect gas pressure, necessitating a full assembly replacement to restore the flame signal.
