gas, Be sure to smell next to the floor because some gas is
heavier than air and will settle on the floor.

with either a gas control knob or gas control lever. Use only
your hand to push the lever or to turn the gas control knob.
Never use tools, If the knob will not tum or if the lever will not
move by hand, do not try to repair it. Call a qualified service
technician. Force or attempted repair may result in a fire or
explosion.

system. Do not attempt to manually light burners on these

burners will automatically light, The ignitor does not get
hot when there is no call for heat on units with an automatic
ignition system,
