If pilot burner is functioning correctly, ensure
adequate flame current as follows:
• Turn off the furnace at the circuit breaker or fuse
box.
• Clean the flame rod with an emery cloth.
• Make sure electrical connections are clean and
tight.
• Check for cracked ceramic insulator, which can
cause short to ground, and replace igniter-flame
rod assembly if necessary.
• Turn on power and set thermostat to call for heat.
The pilot should light and then the main burner
should light.
Replace Igniter-Flame Rod Assembly
Turn off the furnace at the circuit breaker or fuse box.
Remove the spring clip, then the igniter-flame rod
assembly from the pilot burner.
Disconnect the igniter-flame rod assembly keyed plug
from the igniter connection on the SV9500/SV9600.
Remove the igniter-flame rod assembly from the

Check Ignition Cable
Make sure that ignition cable is not in contact with
metal surfaces.
Make sure that ignition cable is not more than
3 ft (1m) long.
Check electrical continuity of ignition cable.
Check Grounding
If ground is poor or erratic, safety shutdown will occur.
Therefore, if frequent shutdowns are reported, check
that ground is made through the pilot tubing.
Excessive temperature at the ceramic flame rod
insulator will permit electrical leakage to ground.
a.
If bracket is bent, bend it back to correct position.
b.
If insulator is cracked, replace igniter-flame rod
assembly (Q3400A).
