Gas Control/Thermostat Inspection
Once a year, visually inspect the gas control/thermostat
cover, gas control knob and status light for any physical
damage. Check for any loose connections or frayed
wires as well.
Pilot Light and Burner Inspection
Once a year, visually inspect the pilot light, then the
main burner while in operation. Through the sight glass,
confirm that both flames are blue and exhibit the pattern
shown in the illustration below. If a different flame pattern
or color is noted or soot has built up on the burner,
turn off the water heater and call a qualified service
technician.
