10. Make sure the Unload switch is OFF.
11. Open the main fuel supply valve on the tank if using LP gas, or the valve in the fuel supply line if using
natural gas. Open the manual shut off valve to allow fuel flow to the dryer.
12. The dryer should be filled with grain. Turn the Load Auger switch to the AUTO position. In both
the AUTO and MANUAL positions, the Dryer Grain Level switch will automatically keep the dryer full
of grain. In the AUTO position, the dryer will shutdown after a preset time period according to the out
of grain timer.
13. Turn each Fan switch to ON. The fan will start and the switch will illuminate when air pressure
is detected.
14. Start each burner by turning the Heater switch ON. After purging for approximately 10 seconds, the
burner will fire and the Heater switch will illuminate. This indicates that the flame sensing circuit is
sensing burner flame. For information concerning burner adjustment, see the dryer pre-starts checks
on
Page 46 of this manual. Set the plenum temperature setpoints to 180°F.
15. Look in PNEG-1650/PNEG-1651 for the full heat chart settings that correspond to the model of
dryer being used. Note the settings for initial moisture, moisture removed, approximate dry time,
1 Speed, 2 Speed low and 2 Speed high. Select the line that has the initial starting moisture. These
are the settings that we will be referred to during this start-up procedure.
16. Run the fans and burners for approximate 10% longer than the estimate dry time for the incoming
moisture. Example: Ten points removal is approximately 54 minutes. -10% of 54 minutes is
5.4 minutes, so run the fan/heaters approximately 59-60 minutes.
