Gas Pot Hints
Keep gas tips clean and round. A blue flame is the heating flame. Watch the mouthpiece burner. Clean out metal and dross which forms there due to metal dripping from the mouthpiece.
If the mouthpiece burner does not give a long, blue flame after cleaning, procure a new mouthpiece burner and replace the old one.
A yellow flame indicates too little air in the mixture. This can be caused from too large a hole in the gas tip, air inlet partly closed, dirty burners, or gas burning in the mixer. Sometimes the hole in the tip of the gas cock is too large. The hole can be paned with a small hammer and reamed out with a small broach to the proper size.
The pot burner top plate is fastened by four stove bolts. These bolts become charred and brittle from the heat, and the nuts will be very hard to start. Have a few of these bolts on hand when changing the plates, because the plate must fit tightly to the burner to obtain the best results.
Good slugs can not be produced with dirty burners. Keep them clean. It is better to spend ten or fifteen minutes cleaning the burners than to lose an hour trying to regulate the temperature of the metal.
