The Equinoxâ„¢ commercial tank-type gas water heater is designed for installation on the roof of a commercial building or in other outdoor locations. The water heater has an 80-gallon storage tank and 120,000-Btu input. Because it draws all combustion make-up air from its outdoor environment, the unit eliminates the potential for performance problems caused by negative air pressure inside the building, states the manufacturer. Features include a horizontally mounted insulated storage tank, an optional freeze protection kit that drains the tank in the event of power outages in below-freezing temperatures, and bottom-mounted plumbing and electrical connections. The EMC-5000 electronic control offers optional remote temperature set point adjustment and provides system status indications.
