* (2) Computes and plots averages of glass temperatures on graph paper from temperature charts, using pencil and template to draw lines and circles.
* Interprets graph to determine need for temperature adjustment.
* Turns valve to increase or decrease air and gas supply into burners.
* (3) Tests gas-to-air ratio of burned atmosphere, using gas analyzer.
* Inserts hose of gas analyzer into furnace and starts suction pump to withdraw sample of burned atmosphere.
* Observes dial indicator on analyzer to determine if gas-to-air ratio is in accordance with specifications.
* Turns valve to adjust gas-to-air ratio and control heat of furnace.
* Records tests, temperatures, and adjustments in log.
