My gas furnace exhaust vent that runs through the chimney, touches the gas
feed line into furnace and makes a rattling sound. Is that dangerous? Can i
put something in between the two to eliminate the rattle

Turn water into wine and get ****ed and then get nailed up by the romans.

Put something in so that nothing touches the gas line at all and
I don't see how you will have anything to worry about. I
wouldn't want anything bumping into my gas line.

A very hot sheet metal tube against a gas line?

Make sure you've got the fire department's phone number on your speed

Use a bracket or two to move them apart, assuming there is enough free play
there. If they rattle there is rubbing and if it goes on long enough, it
could wear a hole, presumably in the thinner vent pipe. Sounds like a hack
installed it. Did it pass inspection like that?

I'm sure there is a code that says you can't do that, but I don't see the
science whereby the heat from a home furnace exhaust next to a nat gas line
is going to cause a disaster. I guess you could
come up with a pathological case, where somehow with work on a line you
got the right mix of fuel and air in there, but even then, the exhaust
gas vent heat transferred to a section of gas pipe, isn't going to create
a temperature that's even close to the ignition range. Igniters in furnaces
glow red hot for a reason. It would be also near impossible to get air
and fuel in the pipe at the same time with the furnace running and without
the furnace running, the vent won't be hot.

I would use a bracket or two to move them apart, assuming there is enough
flex there. And check everything else, because whoever installed this,
is a hack.

That sounds like another claim from some whacko source. From what I've read,
there is no real accurate count of polar bears, that we've only begun to
try to count them in recent years and the general scientific consensus is
that at this point some populations have declined, some have increased and
overall it's mixed.

What kind of gas line is it? CSST, copper or black pipe?

What kind of exhaust vent? Double wall metal vent or PVC?

Only potential problem I see is if they rubbed and eventually the
exhaust, usually thinner, would get a hole and allow fumes in.

A dozen years back we upgraded some gas boilers at work and the gas
company had to install a new larger meter. I will admit, I did not get
too close when they welded the gas supply pipes.

How warm does the gas pipe get where the exhaust pipe touches it?

You could fold a couple layers of fiberglass cloth and slide it between
them. Or just re-position the vent pipe a bit. Maybe just run a wire
around the vent and pull it away a bit to get rid of the rattle.

Did they teach you that at MIT?
