6-3 Shut Down Mode

When tank water temperature reaches 172º F the heater will enter into the Shut Down
Mode of operation.  In this mode the Feed Auger, Combustion Air Blower Assy and the
Stir Rod/Combustion Air Distribution Assy will be off.  To prevent overheating the pump
will run continuously.  The heater will remain in this mode of operation until the tank
water temperature reaches 170º F.  At this point the heater will enter into the Burn
Mode of operation and all systems will be active.
