Nice Garage Unit Heater
Supply House did an outstanding job replacing the first heater that was unfortunately damaged during shipping. Overall I'm very satisfied with all aspects of this heater. I did a DIY install with a QuickSling mount and Z-Flex Novavent Cat III stainless steel vent pipe. A licensed gas tech performed the natural gas to LP conversion, set the gas pressure and fired it up. It's a good quality unit heater that is relatively quiet and does a great job keeping my finished 2-car garage at a constant temp.
