We have not tried since. Might have to give that a try.

However, there are probably a dozen older Generacs on my street, and every one of them kept running while our two failed.

FWIW - page 8 of the owners manual states that gas pressure should be between 5 and 7 inches of water column. Pretty sure the gas man checked that, but we can have him back to verify what we have.

Service Info Bulletin

Kevin,
Generac sent out a Service Info Bulletin #SIB11-02-HAC. It says that the Nexus controller had under voltage alarms when starting. They give the same part number as you gave #0H6680A with serial numbers pre 6259547.
Best to have a local dealer check into this for you.

Excellent information.
I will speak with them today.
Thanks!

Just tried it.
Same error after she shuts down.

What all was running when they did the gas pressure test? I'm on LP, but I think the last time those guys ran a test (when I installed a new water heater, a Bosch demand type that pulls @125K btu input) it was with at least that unit running. Is the inches of water column a static test, or should the appliances be running at the time?

Yes.

In other words, both a static test and a test with full flow going should be done.

The fellow who set up our new natural gas meter and regulator had a bleeder that he could use to create a gas flow (into the atmosphere) while setting the regulator pressure. He did not have to actually run the appliances.

well, i'm not a tech, but my guess would be that its not a fuel supply issue since any temporary gas delivery issue should be gone by now. Its doubtful that both of your gas meters became defective at the same time.

hopefully you can find a good tech. I'd think Generac would like to know since two units within feet of each other seem to have failed at the same time with the same symptoms.

gas meter?

I was told by our local gas supplier that if you pull to much demand threw the gas meter there is an internal shut off or fail safe valve. If you use more fuel than the meter can supply it shuts down and the only way to get gas back on is to replace the meter.
I don't think this is your poblem but others should be aware of this for future installs.

I have to say that I see various electrical code violations on that install that would certainly not fly around my neck of the woods. The non watertight connector and lack of physical protection on the cables would be a couple of items I could never get the Inspector to agree with.

Consider your garden hose. Just crack open the faucet, in a short period there will be plenty of pressure at the nozzle. Depress the nozzle handle, a quick burst, then just peeing. Same with gas flow, volume and pressure can be tricky.

Kevin, I have a feeling you are not being totally honest here. I do not think this job was permitted or inspected. There is nothing I can see about that installation that is to code. The placement of the generator is one thing, that may just be a simple oversight from not reading the installation guidelines for the generator. That electrical installation is another - if that work was done by a "licensed" electrician he should have his license revoked or his butt dragged before the licensing board. That is one of the worst electrical installations I have seen, including many DIY installations.

This installation screams out "hey lets buy two generators, my buddy knows a guy who is an electrician and installs these things all the time!"
