EXPERIMENT 6: THE REGULATION AND PURPOSE OF A GAS MIXER.—Light a gas burner and then completely close the mixer of the burner. If the mixer is stationary, it may be closed by wrapping a piece of paper about it. What is the color of the flame? Now open the mixer. What is the color of the flame? What substance has been "mixed" with the gas by opening the burner? What is the purpose of the mixer?
EXAMINATION OF A GAS RANGE.—Inspect a gas range and find the following parts: (a) Top burners—regular, giant and simmering (see Figure 13). (b) Stopcocks of top burners. (c) Oven burners. (d) Stopcocks of oven burners. (e) Pilot (if there is one). (f) Baking oven. (g) Broiling oven. (h) Warming oven and its burner (if there is one). (i) Supply pipe. (j) Stovepipe.
The method of lighting oven burners varies in different ranges, and for this reason it is impossible to give directions for lighting which will apply to all oven burners. There is, however, one important direction that should always be borne in mind. Always open the oven door before lighting the oven burners. If such caution is not observed, the gas may escape into the oven and cause an explosion. In case there is a pilot- lighter, open the oven door and see that the oven burners are turned off before lighting the pilot.
