Modine 5H0798060001 Collector Box Gasket Replacement Part Hot Dawg

The Modine 5H0798060001 is a genuine OEM replacement Collector Box Gasket (also referenced as item 48804) designed for Modine Hot Dawg gas-fired power-vented unit heaters. This gasket seals the collector box assembly within the heater's combustion system, maintaining a proper airtight connection to ensure safe and efficient flue gas management.

The collector box gasket plays a critical role in the power-vented combustion system, where the inducer motor draws combustion air through the heat exchanger and exhausts flue gases through the venting system. A worn, cracked, or failed collector box gasket can result in flue gas leaks, pressure switch failures, or combustion performance issues. Replacing it with the correct OEM part restores the integrity of the sealed combustion pathway.
