instructions. If you do not smell gas go to next step.

gas is heavier than air and will settle on the floor.
The gas valve on this unit is equipped with a gas control
switch. Use only your hand to move the switch. Never use
tools. If the switch will not turn or if the control switch will not
move by hand, do not try to repair it. Force or attempted
repair may result in a fire or explosion.
Placing the furnace into operation:
These units are equipped with an automatic ignition system.

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