WIRING
WARNING
Electrical Shock Hazard.
Can cause serious injury or death.
Disconnect power supply before making wiring
connections to prevent electrical shock or
equipment damage. More than one disconnection
may be required.
Follow the wiring instructions furnished by the appliance
manufacturer, if available, or use the general instructions
provided below. When these instructions differ from the
appliance manufacturer, follow the appliance
manufacturer instructions.
All wiring must comply with applicable electrical codes
and ordinances.
Disconnect power supply before making wiring
connections to prevent electrical shock or equipment
damage.
1.
Check the power supply rating on the ignition
system control and make sure it matches the
available supply. The system transformer should be
NEMA rated for 40 VA or larger. An appliance
system power review is recommended. Install a
transformer, thermostat and other controls, as
required.
2.
Connect the 120 Vac power supply HOT lead to L1
on the ST9160 or 208907 Terminal Board.
3.
Appliance chassis must have reliable connection to
earth ground.
4.
Connect control circuit to the ignition system
control using the keyed connector. See Fig. 7
through 10.
Ground Commonality Check
Use a multimeter to check for ground commonality
between the appliance chassis and the neutral side (L2)
of the ac line voltage. Set the multimeter for ac volts and
a range low enough to read ten volts or less. See Fig. 6.
Voltage reading between the appliance chassis and the
neutral side (L2) of the line voltage should be less than
10 Vac.
Fig. 6. Testing for ground commonality.
STARTUP AND CHECKOUT
Ignition System Control Switch Settings
Ignition system control switch settings are as follows:
•
OFF prevents main gas flow through the ignition
system control.
•
ON permits gas to flow through the control body. At
the appropriate time in the appliance operation, main
gas can flow to the main burner.
NOTE:
Controls are shipped with the ignition system
control switch in the ON position. If the appli-
ance is operated with the ignition system control
switch in the OFF position, the system will
respond as if the air proving switch is stuck in
the no airflow position.
Turn on Main Burner
Follow the instructions provided by the appliance
manufacturer or turn up the thermostat to call for heat.
Perform Gas Leak Test
WARNING
Fire or Explosion Hazard.
Can cause property damage, severe
injury or death.
Check for gas leaks with soap and water solution
any time work is done on a gas system.
CAUTION
Equipment Damage Hazard.
Liquid can damage circuitry.
Do not spray soap and water solution on the
SmartValve housing. Do not use an excessive
amount of soap and water solution to perform the
gas leak test. These can damage the control.
Gas Leak Test
1.
Paint pipe connections upstream of the ignition
system control with rich soap and water solution.
Bubbles indicate a gas leak.
2.
If a leak is detected, tighten the pipe connections.
3.
Stand clear of the main burner while lighting to
prevent injury caused from hidden leaks that could
cause flashback in the appliance vestibule. Light
the main burner.
4.
With the main burner in operation, paint the pipe
joints (including adapters) and the control inlet and
outlet with rich soap and water solution.
5.
If another leak is detected, tighten the adapter
screws, joints, and pipe connections.
6.
Replace the part if a leak cannot be stopped.
