Enerco F160551 Gas Unit Heater 50000 Btu/h Natural Gas 115V

Product Description

The ENERCO F160551 is a 50,000 BTU/h gas-fired unit heater designed for heating large commercial and industrial spaces. It runs on natural gas at 115 volts, single phase, and includes a liquid propane conversion kit for job sites or facilities where natural gas is not available. A spark ignition system with a self-diagnostic control module simplifies troubleshooting during commissioning and service calls. The low-profile cabinet design allows installation in buildings with limited overhead clearance, making it a practical choice where standard unit heaters will not fit. Heating coverage reaches approximately 1,667 square feet under typical conditions. This unit is installed by licensed HVAC technicians or qualified mechanical contractors.

The F160551 is suited for warehouses, garages, workshops, agricultural buildings, and light commercial spaces where forced-air gas heat is required. It supports both Category 1 vertical venting and Category 3 horizontal venting configurations, giving installers flexibility in routing exhaust based on the structure. The included angle brackets allow direct ceiling mounting without additional hardware for standard installations. The 1/2 inch gas connection is compatible with common supply line configurations used in commercial and light industrial settings.
