DRYER IGNITION (SOLID STATE IGNITION).
The solid state ignition system lights the main burner
gas by spark. The gas is ignited and burns only when the gas-valve relay (in the electronic controller)
calls for heat. The procedure for rst-time starting of a dryer is as follows:
A. First, review and comply with the “WARNINGS ABOUT USE AND OPERATION” found on the
inside front cover of this manual. Be sure the electrical power supply is connected correctly. The
white (neutral) wire is to be connected to the N terminal while the black (line) wire to the L1
terminal of the terminal block in the rear control box. The dryer MUST be properly grounded.
B. Make sure all gas supply lines are purged of air. Close the main gas shut-o valve and wait for
ve minutes before turning the valve back on.
C. Turn on main electrical power switch. The dryer may be started by following the “OPERATING
INSTRUCTIONS” found later in this manual.
D. Natural gas and liqueed petroleum gas red dryers both operate in the same manner. When
gas-valve relay contacts are closed (indicating a demand for heat), the solid state ignition control
will automatically supply energy to the redundant gas valve. Spark will continue until a ame is
detected by the sensing probe, but not longer than 10 seconds. If the gas fails to ignite within 10
seconds, the gas will shut o for 15 seconds. The control will attempt to ignite two more times in
a similar manner. If the gas fails to ignite after three tries, the gas valve closes and the system
will "lock out". No further attempts at ignition will be performed automatically. It is then
necessary to interrupt electrical power to the ignition system before making another attempt to
light the burners.
This can be done by opening the dryer door, allowing the dryer to come to a stop for 15 seconds,
closing the door, and pushing the "Start" button. The dryer will then repeat the ignition trial cycle.
DRYER SHUTDOWN
To render the dryer inoperative, turn o the main gas shut-o valve and disconnect electrical
power to the dryer.
IT IS RECOMMENDED THAT THE INSTALLER TEST THE DRYER FOR OPERATION AND
INSTRUCT THE USER BEFORE LEAVING THE INSTALLATION.
