Lochinvar & A.O. Smith 100093804 Door
The Lochinvar & A.O. Smith 100093804 Manifold Door Assembly is a critical OEM replacement component designed for Natural Gas (NG) water heaters and commercial heating systems. This TC Ignition Project kit integrates the burner access door with an optimized thermocouple and igniter setup to ensure precise gas flow management and consistent pilot performance. As a veteran technician knows, maintaining the integrity of the combustion chamber seal is non-negotiable; this assembly provides the mandatory factory-spec fit to prevent rollout and maintain safety standards in BFG40T40N models and similar residential or commercial units.
Engineered to replace legacy part numbers 328540-000, 6910805, and 100086970, this 100093804 manifold door simplifies field repairs by consolidating the manifold, burner door, and ignition components into a single, high-durability unit. The robust construction is tailored for demanding environments where thermal cycling frequently fatigues lower-quality aftermarket parts. By utilizing this genuine A.O. Smith repair part, contractors ensure seamless compatibility with the existing water heater control system, optimizing ignition timing and reducing the likelihood of nuisance lockouts or thermocouple failures.
Key Benefits for the Technician- Direct OEM Replacement: Guaranteed fit for Lochinvar and A.O. Smith units, including the BFG series, ensuring no modifications are required on-site.
- Integrated Ignition System: Includes a factory-installed thermocouple and igniter for rapid restoration of pilot and main burner function.
- Enhanced Combustion Safety: Provides a precise seal for the combustion chamber to support efficient gas combustion and proper drafting.
- High-Temp Durability: Manifold door materials are selected to withstand the high-ambient conditions of industrial and commercial mechanical rooms.
Is this manifold door compatible with Propane (LP) units?
No, the 100093804 is specifically calibrated for Natural Gas (NG) applications. Using this assembly on an LP system without proper conversion can lead to dangerous operational conditions.
Does this kit include the door gasket?
Standard K MNFLD DOOR TCIGNTN PROJECT kits typically include the necessary seating surfaces; however, it is standard practice to inspect the existing combustion chamber insulation for damage before completing the install.
What models does the 100093804 replace?
This part is the designated replacement for several older part numbers, including 9006433005 and 6910805, specifically for 40-gallon and 50-gallon high-recovery models.
