7. This furnace is equipped with an ignition device which automatically lights the
burner. Do not try to light the burner by hand.
8. Plug in furnace.
9. Set thermostat to desired setting. If thermostat is set above room temperature,
the blower will come on.
10. Allow approximately 45 seconds for ignition to occur. When ignition occurs,
the glo-bar will stay on for a short period of time. The flame sensing probe will
sense the burner flame and shut off glo-bar.
If ignition does not occur within 22 seconds, the ignition control will attempt to
light burner three times. This will take about two minutes. If ignition does not
occur, the ignition control will lock out the glo-bar and valve circuit. Air in the
gas line or a short gas interruption will prevent furnace from igniting. If this
happens, turn thermostat off and wait 5 minutes. Turn the thermostat back on.
The furnace will try to ignite again.
11. If the furnace still does not ignite, follow instructions To Turn OffGas to
Furnace, page 22. Call as qualified service person. Do not attempt to restart
