BURNHAM 8026032 Glass

When you're out on a service call for a Burnham boiler, a compromised observation port is a safety hazard you can't ignore. The Burnham 8026032 Glass is the direct OEM replacement engineered to handle the thermal shock and high-pressure environments of residential and commercial heating systems. This is genuine Pyrex observation port glass, measuring 3.281 inches in diameter with a robust 0.19-inch thickness. Unlike generic alternatives, this glass features a ground and chamfered edge to ensure a gas-tight seal against the port gaskets, preventing combustion byproduct bypass and maintaining the integrity of the chimney-vented system.

For technicians monitoring burner flame characteristics or verifying standing pilot ignition, clarity is everything. This high-temperature boiler sight glass resists the etching and clouding common in older natural gas units. It is specifically designed for Burnham models like the KV905ASOB, supporting systems with capacities up to 112,000 BTU. When performing your annual maintenance, replacing a stained or heat-stressed observation port glass is a critical step to ensure the equipment continues to operate within its original factory specifications.

• OEM Precision: Guaranteed fit with a 3.281" diameter and 0.19" thickness for seamless integration.
• Thermal Resilience: Constructed from high-quality Pyrex to withstand extreme combustion chamber temperatures.
• Enhanced Visibility: Ground and chamfered edges provide a clear, undistorted view of the combustion process.
• Safety Compliance: Maintains the natural gas application seal, essential for chimney-vented safety.
• Durable Construction: Heavy-duty replacement that resists the pitting and cracking found in non-OEM glass.

Is this glass compatible with all Burnham V9 and V11 series boilers?
This specific glass is a standard for many residential Burnham units, including the KV series. Always verify the port diameter (3.281") as some larger commercial V9/V11 models may require a different port kit.

Can I reuse the old gaskets when installing this new port glass?
It is standard trade practice to replace the 8206001 outer gasket and 8206002 inner gasket whenever the observation glass is removed to ensure a proper seal and prevent gas leaks.

Why is the edge chamfered on this replacement glass?
The chamfered edge allows the glass to seat properly within the cast iron housing without creating stress points that could lead to cracking during thermal expansion.
