STARTING THE DRYER

This start up procedure is for a cold start on wet grain for continuous flow

operation.

1 . Set the MAXON or FAST ACTION HAND VALVE on the incoming fuel

l i n e to the ON position.

2 . Make sure the MOISTURE CONTROL switch is in the OFF position.

3 . Turn the FAN switch (or switches if a multi-fan dryer) to the ON posi-

tion. The light in the switch should light when the fan comes up to

about half speed.

4 . Adjust the AIR PRESSURE SWITCH if necessary.

5 . Turn the HEATER switch (or switches if a multi-fan dryer) to the ON

position. The heater will purge for about 10 seconds then ignite. The

light in the heater switch will come on during ignition and will stay on if

the heater ignites. If the heater does not ignite, the light will go out after

trial for ignition and the dryer will shut down, indicating that it did not

l i g h t . I f t h i s happens check gas supply, and all valves in the fuel line to

make sure they are ON.

ADJUSTING THE TEMPERATURE

1 . Set the HI-LOW FIRE PLENUM THERMOSTAT on the left side of the

dryer to the drying temperature that you want to run (180 deg. to 200

deg.). On multiple fan dryers set the heat chambers 30 to 60 degrees

apart. Hottest at the top, most cool at the bottom.

2 . On LP gas models adjust the PRESSURE REGULATOR (high fire) on

the burner fuel line, so that burner will reach the thermostat setting and

switch to (low fire) (pressures may be required up to 25 lbs.). Natural

gas does not have a regulator, but uses a LARGE BALL VALVE close

to the vertical supply line for adjustment (pressures may be required up

to 18 lbs.).

On LP gas models adjust the small RED HANDLED BALL VALVE

(low fire) so that the burner maintains flame then switches back to (high

fire). Natural gas has a BALL VALVE close to the burner control box,

for low fire adjustment.

3 . Adjust the burner pressure so that the burners CYCLES 4 times per

minute (approx. 10 sec. on HIGH--approx. 5 sec. on LOW). When on

HIGH FIRE increasing the pressure with the pressure regulator DE-

CREASES the time spent on high fire. When on LOW FIRE increasing

the low fire pressure with the RED BALL VALVE INCREASES the time

spent on low fire.

4 . On LP gas models adjust the VAPORIZER so the fuel pipes going to

the burner from the regulator are warm to the touch (not hot and cold).
