Who installed the pressure gauge on the gas line? There is probably a good reason why someone turned off the gas and secured it with a tie wrap.

Your house seems to be full of mysteries. Was this work done by a DIYer?

Im not sure i had the AC replaced 2 years ago i bought the house 2 years prior to that and the fireplace worked but we just never used it.If i cut the tie wrap and turn the valve on do you think it would hurt anything i just need to make sure the fireplace works for the new owners.

mike_home,

If that was a temporary shipboard installation on a submarine I'd say it was a temporary pressure connection with a pressure gauge and a Schroeder valve to permit pressurizing with air. The tie wrap on the valve ensures that it is not opened during a pressure top test and also ensures that air will not be introduced into the gas supply.

Does the plumber use such a test rig to do a pressure drop test on new residential gas work?

Saltidawg,

I suppose a plumber could do a leak test. The usual practice is to use a soap solution on all the connections.

p3jarljam,

Can you visually see all the connections on the gas line between the shut off valve and the fireplace. My only concern would be if there is a gas leak. If you turn on the gas you should inspect all the connections carefully.

I was able to contact the guy who did my AC he said that the pressure gauge needsto be removed and capped does that sound right?

p3arljam,

You said, "I was able to contact the guy who did my AC he said that the pressure gauge needsto be removed and capped does that sound right?"

See my post three slots up.

My guess (like others have mentioned) is that the gauge was there for a new work pressure test/inspection, the red valve was closed to prevent high pressure from damaging the gas valve on the log set.

Problems:
1)If that is the case, the line past the valve has not been tested.
2) The valve should be in the same room as the appliance, not in the attic.

I would suggest a whole system leak test and verification that a shut off valve is present in the same room as the appliance.

My AC guy emailed me and said the gauge was for testing purposes only and should be removed and capped off. Does this sound correct?

I think somebody forgot to take their gauge when the job was completed. The gauge should be removed and the pipe capped.

Thanks for the help.

The gauge looks like it was forgotten about...the tie on the gas cock made me think that was copper tubing coming off the valve and was red tagged. Copper and NG or LP is not allowed in this neck of the woods.
