1. Pilot flame is lit automatically. Do not light the
pilot flame manually.
2. Before lighting pilot burner flame, smell around
the appliance for gas. Be sure to smell next to
the floor because LP gas is heavier than air.

• Turn off the gas supply at the appliance ser-
vice valve. On LP gas systems, turn off gas
supply at the gas tank.
• Do not light any appliances in the house.
• Do not touch electrical switches or use the
phone.
• Leave the building and use a neighbor's
phone to call your gas supplier.
• If you can not reach your gas supplier, call
the fire department.
4. Do not force the gas control knob. Use only
your hand to push down or turn the gas control
knob. Never use any tools. If the gas control
knob will not operate by hand, call a qualified
service technician to replace the gas control.

explosion.
