 - Smell all around the appliance area 

for  gas.  Be  sure  to  smell  next  to  the  floor  because  LP/

Propane gas is heavier than air and will settle on the floor.

Use only your hand to move the gas control switch. Never 

use tools. If the switch will not move by hand, do not try to 

repair it. Force or attempted repair may result in a fire or 

explosion.
