I have a ComfortMaker natural gas fired hot air unit Model No.

My problem is the pilot will only stay lilt as long as the gas
regulator selector is dpressed as soon as you let up pilot goes out
have held flame on for ten or more minutes without luck?
this is a standard thermocouple unit using a Model 36C03 Type 245
regulator
the thermocouple has been replaced the pilot tubing is clear the
pilot when lit is blue strong and making good contact with the
bthermocouple.

Don't know the mechanics of your regulator, but I had one I *almost*
replaced.
Then I finally realized the detent was worn and the button had to be
*very* firmly held down for (whatever the thermocouple activated part
is) to engage.

I can't remember details, but an old girlfriend couldn't light her
waterheater. I had trouble too until I finally pushed or twisted
something more than I thought I should have to.

I got there at 11PM. I was done at 11:30 or 45 and then she offered me
something to drink.

I didnt' want to sleep with her, but I thought she should have offered
me a drink before I was ready to leave, like 10 minutes after I got
there, or she should should have offered me a drink and food when I
was done. What say yeL?

I remember her now. When we were dating she had had me and a older
woman over for dinner. The woman and I got pasta, and she served
herself chicken or meat. She had some strange reason she needed the
meat, but we didn't. She also invited me for Thanksgiving near NYC,
200 miles from here, and on the way back read the paper or slept
almost all the way, while I drove her car. She said she was inviting
me since no one else had, but I had the feeling she needed someone to
drive.

That's why I was so picky about how she treated me when I came out at
11 PM to fix her water heater. Who needs hot water that bad anyhow,
come to think of it. That's why God gave us a stove.

So, how long have you been married? And do you have a
chaeuffers license, by now?

I'd want to take another look at how the flame is touching
the thermocouple. Next, I'd consider replacing the gas
valve. Others have suggested knob position, which is cheaper
than gas valve. Or pressing harder on the button, which is
also cheaper.

The pilot flame needs to be hitting the tip of the thermocouple.
Sounds like you believe that is ok. Heating the thermocouple opens a
safety shutoff valve in the gas valve. Make sure the thermocouple
connection to the gas valve is tight as well. Pushing the button in
bypasses that safety valve to allow you to light the pilot. If
everything else checks out then your problem is most likely the gas
valve. Unfortunately those can be pricey. However they are also
really common if you want to try to find a used one or one off ebay.

Assuming the new thermocouple is good, the only thing left is the
gas valve.

How about the nozzle of the pilot light. My ventless has a
thermocouple/nozzle assembly. I replaced it 3 years in a row until I
read to give the nozzle a blast with some canned air. Now they last
4-5 years.

If the op's thermocouple didn't include a replacement of the nozzle,
it might have a speck obstructing the flame enough to not heat the
thermocouple up enough.

The op's original post seems pretty clear that he has closely examined
the pilot flame and checked it's contact with the thermocouple end.
My guess is he's hoping agains odds for a completely new suggestion
other than buying a $100+ gas valve.

Hi,
Tried to adjust flame size? I used to clean nozzle with fine piano wire.

I said she was my ex-.

Another thing -- This was before cell phones, and she had told me she
didn't like or couldn't handle driving in NYCity -- I drove us into
Manhattan on the day after Thanksgiving, a big shopping day, and
parked the car on the street a block and a half from the entrance to
the Queens Midtown Tunnel, which connects to LIExpressway.

She was going shopping and I was going to go visit a friend and his
wife. I said, If they invite me for dinner or after dinner and to
spend the night, is it okay if you assume that if I"m not back at the
car by N:nn, I'm staying with them, and you go home by yourself? She
got angry. "I told you I can't drive in NYC" I said, "I asked if it
was all right. Just say No. And look, right up there a block in front
of us is a sign for the tunnel. Just turn right there and left a
half-block after that, at the next sign, and you'll be on the road to
your sister's." She was still angry.

She did have a good idea, to go to the wonderful aquarium in Camden
and then take a different bridge across the Delaware than the one
backed up with Thanksgiving travelers, but after we got back here, I
resigned my job as chauffer.

Hi,
Tried to adjust flame size? I used to clean nozzle with fine piano wire.

I can definitely see that, with a natural gas nozzle.

But in reading about propane torches, I came across a guy who wanted
to clean that orifice with thin wire. Is that possible? It looks
impossible to me.
