• Perform lubrication checks when needed.
End-of-season equipment shutdown:
• Open the clean-out doors on both sides and let any grain fall through. If needed, the discharge augers can
be run briefly to ensure no grain is left on the topside of a stationary auger system.
• Clean out the rear cross auger.
• For storage, the cleanout doors should be left open so that rain may fall through.
• The belts should be loosened and removed, then stored in a dark place.
• The chains should be removed and lubricated, then stored in an air tight container.
5.3. Burner Gas Ports
Conduct initial inspection within the first month after commissioning. Visually check the gas ports of the new

Annual inspections are normally adequate once the initial piping debris is removed. Heavy usage of the burner
may require checking and cleaning monthly or more.
5.4. Solenoid Valves
All solenoid valves should be cleaned annually. The time between cleanings will vary depending on the service
conditions. In general, if the voltage to the coil is correct, sluggish valve operation, excessive noise, or leakage
will indicate that cleaning is required. In the extreme case, faulty valve operation will occur and the valve may
fail to open or close.
Cleaning instructions and rebuild kits for valves can be obtained online from vendors such as ASCO, etc.
