What are the Benefits and Features?

  • No Need to Re-fuel

As opposed to smaller portable units, this Generac generator is designed solely for back up power supply. That’s why this generator has to be plumbed into your natural gas line. The unit includes the piping, but it should probably be installed by a professional. At the end of the day the times when you need this generator, you’ll be happy you got it properly installed. And it has the added of bonus of endless fuel during a disaster because natural gas lines are underground. So you don’t have to go out of your comfortable home and refuel in bad weather.

In addition, it works very well also in conditions where the natural gas pressure is very low, as it can operate with just 3.5” of water column of pressure.

  • Auto Start

Automatic Power Transfer SwitchThe Guardian 6729, like all in the Generac Guardian series, has the auto start feature. This means when there is a power cut the generator will automatically start within seconds. This specific model includes the Generac 200 Amp automatic Transfer Switch to facilitate this. It is installed in your distribution board and senses when the utility supply cuts out. It will then switch on your standby generator within seconds. You probably won’t even know the power was out.
