RECLAIMER DAMPER (HR-2100B HEAT
RECLAIMER OPTION)

The reclaimer damper, used on C-2100B dryers
equipped with the HR-2100B series heat reclaimer,
must be adjusted to balance the reclaimed air from the
heat zone reclaiming duct to the fan inlet vacuum
plenum.  The damper should be adjusted by opening
the rear reclaimer door and checking for a slight vacu-
um in the duct.  If a positive pressure is noticed (air
flowing out the door), open the reclaimer damper slight-
ly.  If a large vacuum is noticed (air flowing into the
duct), close the reclaimer damper slightly.

NOTE: Making an adjustment change in the fresh-air
louvers may require a slight reclaimer damper adjust-
ment.

HEAT RECLAIMER DOORS

The HR-2100B reclaimer is equipped with hinged
cleanout doors every two feet along the length of the

reclaimer duct.  These doors can be opened for clean-
ing the dryer and reclaimer duct wall.

The dryer can also be operated with the reclaimer
doors in the OPEN position to allow reclaiming air to
escape when full reclaiming is not desired.  In this situ-
ation, the reclaimer damper should be FULLY CLOSED
and the fresh-air louvers readjusted to give the desired
grain cooling required.

C-2100B1 SERIES FULL HEAT DRYERS

FRESH AIR LOUVERS

The fresh air louvers on the C-2100B1 series dryers
should be fully opened during drying operation.

On C-2100B1 series dryers equipped with HR-2100B1
series Heat Reclaimer, the louvers should be approxi-
mately 66% open, creating a slight vacuum in the fan
inlet plenum.  This opening should be fine tuned by
watching the pressure on the hinged skirt doors.  If the
doors are being blown outward by the dryer exhaust
