About the NewAir G73

The NewAir G73 is a small, hardwired heater that offers over 17,000 BTUs of heating power for your garage. It can be mounted on your ceiling or wall, and because it is hardwired, you know you never have to worry about electrical fires or overheating plugs.

The built-in single-pole thermostat makes operating this heater quick and easy. An auto-shutoff feature won’t allow this unit to overheat, so you can always feel confident that you can be both warm and safe. It comes with a swivel bracket and adjustable louvers for maximum control when heating your area.

How to Use

Using the NewAir G73 is quick and easy once it has been installed. Since this heater is a hardwired model, it would be best to get an electrician to install it for you. There are directions in the manual on how to do it yourself, but with professional installation, you can feel safe and confident that it is done correctly.

Once installed, all you need to do is use the built-in thermostat to control how hot you want to make the area. Turn the thermostat knob clockwise all the way for the heating element to turn on. Then you can adjust it lower or higher as desired. To make it run on an automatic cycle, turn the knob counterclockwise, slowly, until you hear a click. That will allow you to keep the room at an even temperature.

To clean this unit, use a damp cloth on the outside of the unit only. Make sure you dry it when you are finished. Use a vacuum to remove any dust or debris that has gotten inside. To maintain the heater, check all of the parts regularly, and if you see anything that looks broken or burnt, stop using it until you talk to a professional.


Safety is important, and the NewAir G73 knows that. This heater comes equipped with an automatic shut-off in case of overheating. Being hardwired eliminates the dangers of exposed plugs and outlets. The metal body keeps the inside components safe while being ceiling or wall mounted with the provided brackets keep the unit high enough to be out of reach of little hands and fingers.

As always, for the most safety with any hardwired product, it would be best to have it installed by an electrician. This heater is UL certified for safety, so you can trust that you can keep your garage warm during cold winter months without putting you and your home at risk. Clean it with a damp cloth, but do not use any type of sprays or liquid cleaning products. Although this heater is very low maintenance, it is still a good idea to routinely check for any problems that may arise.
