Mestek gg075a1nsa11 Low Profile Unit Heater 75000 Btu/h

Product Description

The MESTEK gg075a1nsa11 is a residential and commercial low-profile gas-fired unit heater rated at 75,000 BTU/h on natural gas. It operates on 115 volts with an 82% AFUE efficiency rating and uses a single-stage direct spark ignition system. The heat exchanger is constructed of aluminum. A 1/12 HP open drip-proof (ODP) motor drives the unit. The heater is power-vented and supports either standard vent configuration or separated combustion with the addition of an LP conversion kit. Licensed HVAC technicians and commercial mechanical contractors typically install this unit in occupied or semi-conditioned spaces where ceiling-mounted heat delivery is required.

This unit heater is suited for residential garages, warehouses, workshops, loading docks, and light commercial spaces where a low-profile ceiling-mounted heating solution is needed. The power-vented design allows flexible vent routing, and the separated combustion option supports installations where indoor air quality or makeup air is a concern. The included LP kit compatibility expands fuel options where natural gas is not the available utility.
