LIGHTING

A. This appliance has a pilot which must

be lighted by hand. When lighting the
pilot, follow these instructions exactly.

not use any phone in your building.

from a neighbor’s phone. Follow
the gas supplier’s instructions.

• If you cannot reach your gas sup-

plier, call the fire department.

the gas control knob. Never use tools.
If the knob will not push in or turn
by hand, don’t try to repair it, call a
qualified service technician or gas
supplier. Force or attempted repair
may result in a fire or explosion.
