D. GAS BURNER ASSEMBLY

Gas heated dryers are equipped with a gas burner assembly consisting of three (3) burner tubes, gas valve, glo bar, flame sensor, sail switch, and hi-limit thermostat. The inlet piping enters through the rear of the dryer on the left hand side (viewing from the front) and runs to the front of the dryer where the gas valve is located.

E. BLOWER MOTOR and IMPELLOR

The impellor on the ML-130 is shaft driven. The blower motor drives the shaft on which the impellor is mounted. This enables the impellor to run at a higher RPM, thereby producing a higher airflow (cfm).

F. IDLER ASSEMBLY

(Viewing from the rear of the dryer) the idler assembly is located approximately on the lower center of the dryer. The idler assembly consists of two (2) idler pulleys, (small and large). The idlers’ main purpose is to reduce the speed and increase torque provided to the tumbler (basket) bearing. Also, at the idler assembly, belt tension can be adjusted.
