My LP installer said that the tank and the vent nozzle for the regulator had to be at least 10 feet from any potential source of ignition, not just the generator.

Regarding the regulator vent distance, the code is NFPA 58 3.2.12.5, in case the gas supplier asks. Others have mentioned that local codes may require a greater distance than 5'. I believe Skip previously mentioned 6' in his neck of the woods.

Our regulator is within 5' of our generator, however the vent in the regulator is piped almost 6' away from the generator. See the code for more details on piping permitted.


Thanks, 'genme,' I found the NFPA and read the relevant section, and I'll consult with our supplier about those specs. I'm sure that 5' would do it here.....in our county, I doubt if you could find anyone who's even heard of the NFPA, outside of the one municipal fire department and a dozen volunteer FDs. Along the same lines, I suspect that the electrical contractors are the only ones who really see that the NEC is met....or not.

Meantime, today I ran section 2.4 of the owner's manual, "Electrical Checks," and everything tests within spec. I don't have any way to check the frequency output, but expect to have that soon. Next up are the load test and automatic operation. That ought to wrap everything up except for putting it into service.

They didn't use the flex coupling. The line coming in is a flexible yellow plastic inside that gray conduit. Plenty of flex, they said, doesn't need the vibration isolation. From what they told me, they've been going to this yellow plastic line in the LP business.....the NG company around here has been using it for over 20 years. There is a shutoff within sight of the genset, just not in the picture.


Hate to burst your bubble but that LP gas line installation is awful. No support, no flex connection, no venting, not shutoff, no drip leg... Not professional at all - I don't care how long they have been in business. I know you don't have inspections but that install would not pass inspection anytime, anywhere.

Thanks for your observations, 'bucdup'- I'll be consulting with my LP supplier on all these issue.

Hate to use such harsh language but that installation just screams problems. The vibration alone could cause serious and dangerous issues over time. Any LP installer with that many years in the business should know better. The fact they are telling you different is kind of disturbing.

I'm far from an expert, but it looks to me like you are looking for trouble by hanging that regulator off the generator like that. The combination of the weight of the regulator and pipe combined with no significant flex (yes, there is a flex line feeding the regulator, but with it coming straight up out of the ground, I suspect it gives very little flex) I think it would be putting (or will be putting) undue stress on the fuel solenoid inside the generator.

The generator ships with a flex hose for a reason. It should be in place as per the installation instructions.

I know it is disheartening to have a bunch of people tell you your brand new generator install is full of code violations and looks like crap but..............
The fact you live where there are no inspections is the real pain, and let this be a lesson to every one else, this is why there is a need for permits and inspections. I will assume you have already paid the contractors, I hope I am wrong, with permits and inspections the homeowner now has a leg to stand on to with hold payment for the work until the code violations are corrected. If you have paid for the work it may be very hard to get them back to correct the problems.

I have found some info from a contractor in Ind. He states that if you live where they do not require permits or they do not have an inspection dept. that you are supposed to call for a state inspection. Your state law requires an inspection on any contracted work. So you have a recourse if you need it to get the problems corrected

No worries, guys, if I didn't want the observations and criticism, I wouldn't have put the pictures up. Problems are noted, and will be resolved one way or the other.....

My DMM that does frequency measurement came in, and today I performed test 2.5, "Generator Tests Under Load." Everything went fine, all readings were nominal. Now all I have to do is run the test for automatic operation, and I can put this thing into service.

Performed the final test, 2.6 "Automatic Operation," and everything went fine. Placed generator on Auto in standby. I think this installation thread is over.
