D. DIRECT SPARK IGNITION (DSI)
MODULE (GAS MODELS ONLY)
The DSI module is a 24 VAC device designed to be
the “controller” of the DSI system. When activated
by the dryer controls, this module constantly monitors
and controls the functions of the DSI system (i.e., spark
activation, gas valve off and on, flame verification, etc.).
Additionally, the DSI module has self-diagnostic
capabilities.
E. GAS BURNER ASSEMBLY
Gas heated dryers are equipped with a gas burner
assembly consisting of four (4) burner tubes, gas valve,
spark ignition probe assembly, 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.
F. DRIVE MOTOR
The totally enclosed, fan-cooled (T.E.F.C.) drive motor is
located approximately lower center of the dryer. It sits
on an adjustable base so that the motor can be easily
adjusted to the left or right, up or down, forward or
backward. The drive motor is a 1 HP (0.75 kw) motor
and operates on 208 to 460 volts, 3-phase (3Ø), 50/60 Hz.
