7. 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 first-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-off valve and wait for five 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 liquefied petroleum gas fired 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 flame 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 off 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 off the main gas shut-off 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.
