Lochinvar & A.O. Smith 100288663 Insulation
The Lochinvar & A.O. Smith 100288663 Burner Plate Insulation Door is a critical thermal barrier designed for high-efficiency gas-fired boilers and water heaters. Engineered from high-density ceramic fiber insulation, this OEM component sits behind the burner mounting plate to contain combustion heat within the chamber. By preventing radiant heat transfer to the exterior cabinet, the 100288663 insulation maintains peak thermal efficiency and protects sensitive external controls from heat damage. This burner door gasket and insulation assembly is a direct replacement for 100288663, ensuring a precise fit and an airtight seal against the combustion chamber. For field technicians, replacing a cracked or degraded burner plate insulation is a standard preventative maintenance step to resolve rollout issues and optimize fuel-to-air ratios. This lightweight, 0.74-pound part is designed for rapid installation on professional-grade Lochinvar and A.O. Smith heating systems, maintaining the structural integrity of the burner assembly under extreme temperature cycles.
Key Benefits:- Maximum Thermal Retention: High-grade ceramic fiber reduces jacket heat loss, improving overall system AFUE ratings.
- Internal Component Protection: Shields the burner plate and gas valves from excessive heat, reducing the risk of premature part failure.
- Direct OEM Compatibility: Specifically engineered for a drop-in fit on A.O. Smith and Lochinvar residential and commercial units.
- Improved Combustion Safety: Proper insulation prevents heat rollout and ensures stable internal temperatures for the burner assembly.
When should the burner plate insulation be replaced?
Replace the 100288663 insulation if you observe visible cracking, "hot spots" on the unit's exterior, or if the material has become brittle and degraded due to excessive thermal stress.
Is this part compatible with other boiler brands?
While designed for A.O. Smith and Lochinvar systems, compatibility is based on the specific OEM part number. Always cross-reference the 100288663 part ID with your technical manual before installation.
Does this include the burner door gasket?
This part is the primary burner plate insulation door component. For a complete seal, ensure the surrounding burner door gasket surfaces are clean and intact during the swap.
