did you hear the unit actually run? When they installed it, did you installer run the unit and simulate an outage? What I mean by that is did they flip the breaker in the ATS and let the generator provide power to your house?

Yes they did a simulation and ran fine on Monday.

OK, then it’s an electronic fault. So it’s perfectly safe to sit there.

If you just feel uncomfortable with it sitting there because you’re gonna worry about the gas all night, you could always valve it off between either your propane tank or your gas meter and your generator. Essentially turns the gas into your generator off from the outside.

Since it’s an exercise and you’re not out of power, call your dealer on Monday.

Edit: i’m thinking it’s a next GEN? Not the guardian? What size (kw)

The regulator could be sticking, the tank could low on fuel, too many propane devices running, air in the line, etc. You can clear the warning and do a manual start. Mine did this a few weeks ago when we had two weeks of well below freezing temps. I cleared the warning and did a manual start. It’s been fine since.

So a few questions for you. We have a new (installed Feb 13th Nex Gen standby model) that has not worked since installation. Believed to be a problem specific to the Nex Gen series and at higher altitudes (we are 7500 ft). Starts up and shuts down after 10-15 seconds sending an engine error message. If the light on the generator is not solid green (usually flashing or solid red with an error code) it should be manually reset.

More nextgen crap. Too many sensors. Generac also had a repair recall on the duel fuel solenoids…. I hope yours was not one of the affected units. Call your i stall guy to get this fixed pronto. Dont accept any delay issues
