I am looking for answers if anybody has had success on installing a commercial gas furnace next to a large air handler used to supplement the free heat from refrigeration. Will the gas furnace work to heat the airflow when it is drawn off from a large commercial duct? It would be ducted out of the main large supply duct, through the commercial furnace and then ducted back into the large supply plenum. I don't have room for inline duct heaters line Reznor makes. Any input would be greatly appreciated!
