Mestek gg030a1nsa11 Low Profile Gas Unit Heater 30000 Btu/h

Product Description

The MESTEK gg030a1nsa11 is a residential and commercial low profile gas-fired unit heater rated at 30,000 BTU/h on natural gas. It operates on 115 volts and delivers 83% thermal efficiency through a single-stage direct spark ignition system with an aluminum heat exchanger. The unit is power vented and ships ready for standard venting or separated combustion with an LP conversion kit included. A 1/20 HP open drip-proof (ODP) motor drives the fan. At approximately 70 pounds, it is a self-contained forced-air heating appliance suited for overhead suspended installation by licensed HVAC technicians.

The gg030a1nsa11 fits residential and light commercial applications where ceiling height is limited and a low-profile cabinet is required. Typical install locations include garages, workshops, warehouses, utility spaces, and small commercial bays. The power vented design allows flexible vent routing, and the separated combustion option makes it viable in tight or semi-sealed spaces where indoor combustion air may be restricted. The included LP kit provides field-convertibility to propane without sourcing a separate orifice package.
