I had to climb over the brick that the homeowner $hit in the crawl space...Originally Posted by hvacvegas

So what happened there? It chafed, and ignited somehow? Or was it a lightning arc that popped a pinhole in the flex connector, and ignited it simultaniously?
Illegal to use that type of connector and pass through, into another space.

Wow. Some folks are lucky to be alive right about now.

That is so sad
How do you sleep at night knowing you did that

I don't take it from the OP that he did that.

I think he was referring to the hack that did it originally.

I am not sure how it ignited. He had been smelling gas for about a week. Intake pipe was laying on the ground so I would assume it pulled gas in there and lit it.
Professional Member
How do you smell gas for a week and not do something about it? I guess its no worse then the call I found a cracked hx on, the renter asked if that was what had been setting off her carbon monoxide alarm, she then said it was real annoying so she took the batteries out.

You would have to know the guy. I swear it could have leaked for 6 months before he did anything... His girlfriend is the one that finally said something.

the issue is not the flex, but its improper installation!!
a flex is fine when instructions, common sense and codes are followed and the only way to connect a stove, clothes dryer or other moveable appliance. they are also code in some municipalities for earthquake safety.
The Food Stamp Program, administered by the U.S. Department of Agriculture, is proud to be distributing the greatest amount of free meals and stamps EVER.
Meanwhile, the National Park Service, administered by the U.S. Department of the Interior, asks us to "Please Do Not Feed the Animals". Their stated reason for this policy "... the animals become dependent on handouts and will not learn to take care of themselves."

The OP did not provide adequate information on this but from the pics, it would appear the installer ran gas piping through the return panning, which is not allowed by code, nor is installing a shutoff in a confined space, much less an air duct and certainly flexible appliance connectors are not tested or listed for use in confined unventilated spaces passing unprotected through sheetmetal. Hard to tell from the pics but if the flex was damaged down by the gas combination valve, it could be sucked up into the return where, once ignited down by the valve, could explain the burn pattern.
I agree with Pacnw: instead of vilifying the product, condemn the improper installation and mis-application of the product. Used properly, they have an excellent track record.

OMG!!!!!!!!!!

Yeah, the code here is that the entire flex must be visible and easily accessible. That's a definite code violation and improper use of a flex.
Professional Member
all mechanical codes state that UNIONS must be readily accesible!!!
gas flex is a union!
and flex lines can not pass thru cabinets.

Hmmm... Seems to me an install issue, not a product issue.
While we are on the subject of flex gas hoses... I am glad they are coated now.
We mostly use 18" flex gas hoses as a 'connector' between the shut-off and the pipe coming out of the furnace (drip leg is on the pipe coming out of the furnace). They are nice for this application. IMO flex gas hoses should NEVER touch anything... NEVER!

Here in CA, or at least the Bay Area CA, these gas flexes are a requirement rather than an option. It is part of earthquake safety. So it is not optional to hard pipe it all the way. Those would be called as a safety hazard by the City inspectors.
Professional Member
correct
as long as they do not pass thru a cabinet and are readily accesible.
we usually run all the black iron in the furnace cabinet and stub out a couple inches, then flex and then gas cock and drip leg.
