Lochinvar & A.O. Smith 100208060 Insulation

The Lochinvar & A.O. Smith 100208060 Insulation is a critical OEM replacement part designed specifically for the burner plate door of high-efficiency condensing water heaters and boilers. This high-density refractory component, also identified by part number FIB2168, measures approximately 187mm in diameter (7.25 inches) and is engineered to withstand the intense thermal cycling found in the combustion chamber. It is a precise fit for Lochinvar Knight and Shield models, including the KBN080-500, AWN-1, and SNR150-100 series. Maintaining the integrity of the door insulation is vital for protecting the heat exchanger access door from warping and ensuring optimal combustion efficiency. When performing annual maintenance, technicians should inspect the burner plate insulation for cracks or degradation to prevent heat bypass, which can lead to localized overheating and equipment failure.

• Precise OEM Compatibility: Verified for use in Lochinvar Knight KBN and Shield AWN/SNR series for a seamless 187mm fit.
• Superior Thermal Resistance: Engineered to handle high-temperature combustion environments, protecting the burner door assembly.
• Optimized Energy Efficiency: Reductions in heat loss through the access door help maintain the unit's high-efficiency rating.
• Durable Refractory Material: Designed for long-term stability under regular boiler firing cycles.

Is the 100208060 insulation different from the FIB2168?
No, these part numbers are identical. Lochinvar transitioned from FIB2168 to 100208060, but the technical specifications and dimensions remain the same.

What are the signs that my burner door insulation needs replacement?
Look for visible cracks, crumbling edges, or discoloration on the insulation face. If the door's exterior surface shows signs of excessive heat or paint peeling, the internal insulation is likely compromised.

Does this part include the mounting hardware or gaskets?
This SKU covers the 187mm insulation disk only. It is highly recommended to inspect and replace the burner door gasket (such as 100208088) simultaneously to ensure a proper airtight seal.
