Why is my stove working?

I smell it every time I turn on the gas valve
My Bad.:facepalm:

I have a 500 gallon Propane Tank at my house.

Mercaptan is added to give the "Rotten Cabbage" smell.
Since Propane must boil to make gas, smaller boat size tanks mixes the Mercaptan well.

Ah…so the mercaptan can “settle” in a large tank? I didn’t know that.

thanks,

I stopped by the yard today. I had forgotten to close the propane tank valve when I left. Stove still works perfect. I'm stumped
I'm going to ask possibly a dumb question - How long did you hold the bypass valve open before you did the flame test where you got it working? How many BTU's was the burner that you did this with?

I know with my stove, when I leave it for quite a long time and come back to the boat, I don't have the patience to get the stove going with one of my two smaller burners. I will start up using my 11,000 BTU burner that has a double gas ring. It still takes more time than I like, but it's a whole lot less than trying to do it through one of my 7000 BTU burners... I'll often actually open up both the 11,000 BTU burner and one of the 7000 BTU burners... I don't have enough hands to do both 7000 BTU burners and the 11000 BTU burner.

On my boat, I don’t have thermal couples on the burners, just on the oven. I always use the external solenoid when not using the stove.

If the propane had been shut off for a long time, it takes time to get propane to the burner. If I put a flame to the burner, the flame is pushed by air flow coming out of the burner ring, but no propane catches for a bit (10-20 seconds?). Once I use it, and if I use it daily, it catches almost immediately.

This thought did cross my mind. I have a wall mounted, ventless heater that does the same thing. First time you open the valve on the pipe it does nothing, even if you smell gas. If I leave the pipe valve open and the heater's knob off for a few days, then it'll fire up on the first or second try. I was hoping to try this but I left the tank valve open. I'll try it this week.

I'm surprised that your stove on a 1988 boat doesn't have a thermocoupler.

Sometimes you need to look up and just say… THANK YOU!:biggrin:
The engineer in me really really wants to know

Hahaha - yeah I very much understand... The problem is can you reproduce it? You might have had some kind of airlock that the heat helped unblock. There are so many possibilities that unless you can reproduce this - you may never know...
