Questions and answers
does a udx 150 require a combustion air vent when installed in a commercial wood shop
Yes, the Reznor UDX 150 requires sufficient combustion air for installation. It must be supplied with air that enters the combustion process and is then vented outdoors. Enough air must be provided to ensure there is no negative pressure in the equipment room. If the commercial wood shop is tightly sealed, outside air may need to be introduced through wall openings or ducts.
