MOTOR ROTATION OF CONVECTION
BLOWERS
The correct motor rotation amperage draw for
most Blodgett Conveyor ovens is 1 amp. If the am-
perage draw is less than .5 amp, check for proper
motor rotation direction.
1. Remove the back of the oven body to check
motor rotation direction. See Figure 9.
Due to the vertical positioning of the motors in
Blodgett Conveyor ovens, the motor direction is
reference from the end of the motor (EOM) as
viewed from the rear of the oven. In the follow ing
figure all directions are taken from EOM.
VENTILATION
Ignite a smoke bomb inside the oven cavity. Note
the amount of smoke removed by the ventilation
system. The minimum recommended amount of
exhaust volume t o be removed is 80%.
