Turning off pilot flame in Gas Boiler?

We have a central heating unit which is Gas operated, yesterday my wife turned off the Gas to the whole house instead of the water line by mistake so the pilot light in the Gas furnace went out. We have been living in this house for 11 years and we never out the pilot light after the winter, I can get someone to relight it in the fall later this year but my question is, is this safe the way the light went out and can I leave it like that until the fall?

I am asking because I don't know if this works like a stove where if the pilot lights go off then you smell Gas all the time?

There are two schools of thought as to leaving a continuously burning pilot burning in the non-heating season. If your boiler room (basement) is dry with a relatively low relative humidity it serves no purpose to leave it burning. However if you have a damp basement then the continuously burning pilot may help in retarding the formation of rust in the boiler's combustion chamber. I personally do not advocate leaving a continuously burning pilot burning during the non-heating season.

Of course, if your boiler also provides your domestic hot water you have no choice but to keep it burning.

If you decide to leave the pilot off you need to close the gas valve located at the boiler. While there is an automatic pilot safety valve that shuts off the gas flow if the pilot is accidentally extinguished for safety you really need to close the gas valve before the pilot safety valve.

The gas pilot may stay on depending on the type of gas control system. The newer styles are designed to shut the pilot off.

Pilot

I find boilers with a constant pilot to stay much cleaner than those with electronic ignition or ones on which the homeowner turns off the pilot. The slight bit of heat the pilot generates helps to reduce or eliminate condensation. As Furd pointed out, if you live in an area of low humidity the pilot probably wouldn't make much difference.

I checked last night, when I opened the boiler door I can smell gas but when I put the door back on, no gas smell. This appears to have an electronic ignition but there aren't any instructions anywhere so I have called a heating guy to show me what to do each year or simply how to properly turn off and on the pilot. What I can't figure is when my wife turned of the gas to the house then why didn't the separate water heater pilot shut off too?

Pilot staying on

These are outstanding reply's to that question.

Our's is close.

Today we turned on the Furance for the first time this season. It did not start heating so I checked and the force had stop blowing. As I was working to get it going I heard a buzzing sound for a few seconds and then it stopped.

Unsure of what it was I cut off the gas and the thermostat. The buzzing happen again and has been going on and off since then (first heard about 9:50am this morning).

The pilot is still lit and has not gone off. The instruction mentions a main swith which I can not seem to fine.

Please help.

Mr. Redhawk.....!
