This prevents dangerous combustion leaks and ensures the HVAC burner assembly operates at peak thermal efficiency

Can I use a different probe length for this application

provided the 1/3 HP and 115V electrical ratings match

The 7B switch provides a proportional 135-ohm signal for modulating feed water systems

or inconsistent manifold pressure leading to erratic flame patterns

Lochinvar & A.O. Smith 100145536 322838-754 This prevents dangerous combustion leaksThe Lochinvar & A. O. Smith 100145536 is a critical Insulation Bottom Cover Frame (INSULBTMCF) designed to maintain the thermal integrity of the combustion chamber in high efficiency boiler and water heater systems. As a veteran tech, you know that degraded base insulation leads to excessive cabinet heat and lost efficiency. This OEM replacement part provides a high temperature thermal barrier at the unit's base, ensuring that heat energy is directed
