ADJUSTMENTS AND CHECKOUT • MAINTENANCE
MODUTROL MOTOR WITH Q100A LINKAGE
AND V51E (FIG. 4)
Minimum Flow Adjustment
Using the motor, drive the valve to the closed position.
Loosen the lock nut on the stop screw. Turn this screw in
against the operating lever until the desired minimum flow
position is obtained. If fully closed is the minimum position
desired, back the screw out until its threaded end is flush
with the stop bracket. Tighten the lock nut.
Maximum Flow Adjustment
With motor in closed position, loosen the lock nut on the
stop screw. Turn this screw in against the operating lever
until desired minimum flow position is obtained. If fully
closed is the minimum position desired, back the screw out
until it ends flush with the stop bracket. Tighten the lock nut.
MODUTROL MOTOR WITH Q100B LINKAGE
AND V51E (FIG. 5)
1. Loosen setscrews in upper ball joint to allow linkage
rod to slide freely. Loosen lower ball joint so it slides freely
in the actuating arm slot
2. Short the motor terminals red to white to drive the
motor closed.
3. Hold valve butterfly open at the desired low-fire posi-
tion and tighten the lower ball joint hand tight against the
outer end of the actuating arm slot. Tighten screw in the
upper ball joint enough to provide some friction on the rod,
but not enough to prevent it from sliding if the valve reaches
its stop
4. Short the motor terminals red to blue. As motor drives
open, note the valve travel. Reset the lower ball joint to the
proper high-fire valve position.
PACKING THE VALVE
No field maintenance is required.
LUBRICATION
Place a few drops of SAE20 or heavier oil on linkage
bearings whenever required. The motor needs no lubrication
in the field.

NOTE: When the lower ball joint is moved, the upper ball
joint usually must be readjusted if the valve is to keep the
same low-fire position
ACTIONATOR MOTOR WITH Q100C LINKAGE
AND V51E (FIG. 6)
Minimum Flow Adjustments
Using the motor, drive valve to the open position. Loosen
the lock nut on the stop screw. Turn this screw in against the
operating lever until the desired maximum flow adjustment
is obtained. If fully open is the maximum position desired,
back out the screw until its threaded end is flush with the stop
bracket. Tighten lock nut.
Maximum Flow Adjustment
Using the motor, drive valve to the open position. Loosen
the lock nut on the stop screw. Turn this screw in against the
operating lever until the desired maximum flow adjustment
is obtained. If fully open is the maximum position desired,
back out the screw until its threaded end is flush with the stop
bracket. Tighten lock nut.
CHECKOUT
Cycle the burner twice through high-fire and low-fire
while observing the actuating arm for smooth operation and
watching the burner flame level for proper regulation of gas
or air. Make certain the actuator arm does not hang up while
the drive motor is in operation.
For detailed operation of drive motor and linkage, refer to
applicable instructions furnished with the device.

Maintenance

MECHANICAL LINKAGES
Mechanical linkages may be devised to operate dampers
or other valves in unison or sequence with this assembly. In
no application should the combined load of the valve,
damper, and linkage exceed the rated load limit of the motor
for its timing. See applicable motor instructions.
