WARNING
EXPLOSION HAZARD. CAN CAUSE
INJURY OR EQUIPMENT DAMAGE.
Only trained professional gas appliance service
technicians should install and check out the S8910U.
Selectable DIP switches allow the ignition module to be
customized for the appropriate trial count, trial for
ignition period, and igniter warm-up time. Use only the
appropriate DIP switch configuration as given in Table 4
on page 7. Refer to Tables 1, 2, and 3 for appropriate
number of ignition trials, warm-up, prepurge and
between trial prepurge timings.
Improper DIP switch configuration can result in
appliance malfunction.

Wire the Module

CAUTION
1. Check the wiring diagram furnished by the
appliance manufacturer, if available, and compare
with Table 5. Carefully follow any special
instructions affecting the general procedures
outlined in this section.
2. Disconnect the power supply before making wiring
connections to prevent electrical shock or
equipment damage.
IMPORTANT
1. Be sure all wiring complies with applicable electrical
codes and ordinances.
2. Hot surface igniter leadwires should not be allowed to
rest against grounded metal surfaces.
3. A common ground is required for the S8910U and the
main burner. The 24V (GND) terminal internally
grounds one side of the transformer. Any auxiliary
controls or limits must not be in the grounded leg. In
addition, the appliance should be earth-grounded.
4. Make sure the transformer has adequate VA. The
ignition module requires 0.4A at 24 Vac. Add the cur-
rent draws of all other devices in the control circuit,
including the pilot and main valves in the gas control,
and multiply by 24 to determine the total VA require-
ment of these components. Add this total to 9.6 VA
(for the ignition module). The result is the minimum
transformer VA rating. Use a Class II transformer
when replacement is required.
5. Check that L1 (hot) and L2 (neutral) are wired to the
proper terminals.
1. Connect the wires to the S8910U Ignition Module as
shown in Table 5. Make sure that adequate system
ground is provided as indicated in the wiring table. See
Fig. 2 through 4. Where a change in quick-connect is
required, cut off the original quick-connect, strip the lead-
wire and firmly crimp in place the proper quick-connect
supplied.
2. Verify the thermostat anticipator setting as explained in
the preceding IMPORTANT, item 4.
