This is the first time I've ever even tested for a gas leak in this area of a furnace. Got a definite positive reading here but I'm not sure if it should be classified as a leak, as it is near what I'd call the jets. The furnace was not running during this test.

Writeup for HVAC contractor. There will be some presence of gas present at the burner orifices when the gas valve shuts down and will take time to dissipate. Honeywell had an article about this an the correct method of testing is a device called a bubbleometer.

Lots of questions are needed. Had the furnace been recently run? How large of a leak did it detect, the detector can pick up small amounts of residue. Have you ever tried sticking the probe in the fire (haha)? Did you know that your detector can identify a cracked heat exchanger?

No.
Unless you have more information to add about sniffer reactions in other locations... The header is not purged at shutdown. There is gas in there. There is no way for it to get out.

Thanks for all the feedback. I didn't write it up. Too many unanswered questions. Referred it to an HVAC guy for other issues, however.
Paul, enlighten me.

We rip open a 12 year old gas-fired furnace, pull out the exchanger, and find a crack.
So cool. It's HVAC training from your office chair! Coming soon.... |
