Burner Ignition
Unit is equipped with a direct spark ignition 100% lockout
system. Integrated Gas Unit Controller (IGC) is located in
the control box. (See Fig. 37.) The IGC contains a
self- - diagnostic LED (light- - emitting diode). A single LED
on the IGC provides a visual display of operational or
sequential problems when
uninterrupted. (See Fig. 40.) When a break in power
occurs, the IGC will be reset (resulting in a loss of fault
history) and the indoor (evaporator) fan ON/OFF times
will be reset. The LED error code can be observed
through the viewport. During servicing refer to the label
on the control box cover or Table 9 for an explanation of
LED error code descriptions.
If lockout occurs, unit may be reset by interrupting power
supply to unit for at least 5 seconds.
