gas regulator vent clearance

[John Dirks Jr]

What is the rule, or is there a rule that the local AHJ decided to not follow in this case?

What came first??

We require a min. 3' clearance from the service regulator vent to a spark or ignition source. I don't really care if there is a receptacle adjacent to the vent, nor do I consider it to be a spark or ignition source (rule up for interpretation).

If gas were venting enough to ignite, the odor would be very strong, and you'd probably hear it venting. If you smelled a strong gas odor, would you be using the receptacle?

Plumbing the service regulator to vent away from an ignition source is typically quick and easy.

Around here that vent would have to be piped 3' away from the outlet.

That's a driveway/garage door there is it?

Going off course here a little but are there guards in front of that regulator to keep errant vehicles from hitting and breaking the high pressure gas line?

If we're talking about spark sources, isn't a running vehicle also an ignition source?

John,

I know that the attachment is not from your area. However, it will give you some of the more commonly used numbers. See page 2.

Using PSE's requirements, John's meter wouldn't comply with several clearance requirements.

While PSE is fairly close to NWN's territory, our requirements are quite different......
