No fuel should come above the bricks in the fire-box, and never should the fire be allowed to get so hot as to make the top of the stove red, as that warps the iron.
The same principle of combustion is found in a gas stove, the air uniting at the point of burning with the gas coming through the pipe. The flame of a gas stove should be blue with a light-blue center. If it burns with a yellow flame, it is not adjusted correctly and the gas company should be notified. The oven doors of a gas stove should always be left open while it is being lighted until all the burners have caught, in order to prevent a pocket of unburned gas from collecting in the oven.
Stoves of all types must be kept clean. They should be rubbed often with paper, and anything spilt in the oven should be scraped up carefully. Gas-burners as well as the tops of a gas stove can be removed and washed thoroughly at the sink with boiling water and washing-soda. Blacking makes stoves look better and preserves the iron.
