OPERATION
5. Turn the heat switch to "I" (on). The ignition
system goes through a 45-second purge time after which
the pilot lights and ignites the burner. If the burner does
not ignite, the red light on the "RESET" pushbutton switch
will light. The RESET switch must be pushed to restart
the ignition sequence. This restarting can be repeated;
however, after 15 minutes, the control system goes into
automatic 'lockout.' When 'lockout' occurs, the heat
switch must be turned to "0" (off) before the restart
procedure can be repeated to ignite the burner.
6. Set the conveyor speed controller to the desired
value.
7. Turn the conveyor switch to "I" (on).

ture can be changed.
