hi..

Last night i smell some gas in my home. I don't know why. I call to the company and they said that the leakage is minor and leakage is from the furnance. Now i have my detector and is working fine.

I light a cigarette and start troubleshooting the problem [pipe]

I get worried.

There are acceptable limits of gas tightness, but these need a manometer and a shutdown of the system to pressure up and measure.

One thing I have learned over many years is that leaks, especially gas, don't get better by themselves.

One house I lived in had gas pipes built in but we were not connected to the grid until some time after we moved in. Then when the boiler started / stopped you got a "whiff" at a certain place then it went away. Eventually we decided to dig up the concrete floor, found the pipe about 1/2" below the surface with a nail from the carpet gripper stuck in it....

in an enclosed space, gas can easy build to the magic concentration limit.

I would not mess with it - isolate the system, get it pressure checked, find the leak, fix the leak, sleep happy.

Mix up some soapy water and go bubble hunting.

Gas leakage is a minor thing? [neutral]

If it's a fart - yes!
 
I wish I could diagnose a minor leak over the phone! Is this the start of smellivision?

Use a tele-scent then, not a tele-phone [peace]
 
maybe the OP took emmanualtops advise and it has gone BOOOOM!

anyone seen a big flash on the horizon recently?

LittleInch, I was quite serious about troubleshooting [upsidedown] I would never advise something unsafe.
According to experiments carried by US Bureau of Mines, "a smoked (puffed) cigarette would only ignite methane air mixture if the latter were caused to flow across the glowing cigarette at 1000 ft per min. Attempts were made to ignite propane, petrol and butane with lighted cigarettes without success and similar results were obtained with white spirit".

More at:
So unless the troubleshooter comes with the top of his/her burning cigarette directly to the leak hole where gas flows at critical velocity, nothing serious should happen.

Interesting. Not sure what happens about the action of lighting the cigarette in the first place, but assuming this is true, how would it help you find the leak?? If you hadn't added the link I would have taken one look at the date and assumed the worst.

I fear the worst for the OP though!

Good troubleshooter always has a portable gas detector on these occasions, as a part of PPE. Come on, you know these things better than I do.

My concern is that the OP can smell the gas but the detector remains silent for all this time. It should be checked when it was the last time it was serviced and calibrated. These things cannot hang there forever without maintenance.

I guess the OP did some smoking while troubleshooting.
