21. Check the manual shut-off
valve shown in Figure 11.45 to
be sure it is in the on position.
22. If 12 volts was not measured
in Step 18 and the Gas Valve
did not open or there were no
sparks to the Burner, and the
check lamp did not go out,
replace the Ignition Module.
23. Check for 12 volts DC at the
gas valve terminals as shown
by Figure 11.46.
A. The valve will show 12 volts
at the valve only during a
trial for ignition or when
the flame is burning.
B. If 12 volts is not measured,
replace the Ignition Module.
Note: Be sure that the mod-
ule is not in lockout, since
12 volts is de-energized
during lockout and the
module would be replaced
unnecessarily.
C. If you have 12 volts and the
valve did not open, replace
the valve.
24. If the Ignition electrode does
not send sparks to the Burner,
check the electrode wire for
continuity as shown in Figure
11.47.
