3.Push in gas control knob and slightly turn clock- wise to the OFF position (see figure 16).

Note: Knob cannot be turned from PILOT to OFF unless knob is pushed in slightly. Do not force.

4.Wait five (5) minutes. Then smell for gas, in- cluding near the floor. If you smell gas, STOP! Follow “B” in the safety information above. If you do not smell gas, go to the next step.

5.Push in gas control knob slightly and turn coun- terclockwise to PILOT/IGN and depress for five
