Modine 5H0799530001 Flame Rectification Amplifier for Gas-Fired Unit Heaters

The Modine 5H0799530001 is an OEM replacement flame rectification amplifier designed for use in Modine gas-fired unit heaters. This component plays a critical role in the burner control system by detecting and confirming the presence of a flame during the ignition sequence.

Flame rectification amplifiers work by processing the micro-amp DC signal generated when an active flame bridges the sensor rod and the grounded burner assembly. The amplifier reads this rectified signal and communicates flame confirmation to the heater's control board. If no valid signal is detected within the required startup window, the control board will shut off the gas supply to ensure safe operation.

Key Features:

• Genuine OEM Modine replacement part (MPN: 5H0799530001)
