this specific steam cylinder is factory-validated for Lennox HCSTEAM systems and should be used only with matched OEM equipment

Upgrading or downgrading heater kW requires verifying that the existing wire gauge (AWG) and circuit breaker size are rated for the new amperage load

This assembly includes the lead wires and transition gaskets required to restore optimal combustion airflow and prevent common pressure switch fault codes in Lennox HVAC systems

Reznor 43594 Flame Sensor 322838-753 note that the Lennox 60L27The Reznor 43594 Flame Sensor is a critical safety component designed for precise flame rectification in high performance heating equipment. As an authentic OEM Reznor part, it ensures the ignition module receives a consistent microamp signal (typically between 3 to 10 A), preventing the short cycling or lockout issues common with worn or carbon fouled sensors. Engineered to withstand the intense thermal stress of gas fired unit heaters, this sensor
