Troubleshooting - Baso BG1600M Installation Instructions Manual

Sequence of Operation
The heating cycle start when a call for heat from the
thermostat supplies 24VAC to the TH terminal. The
automatic vent damper (if used) is energized and when
fully open, turns on the power to the ignition control. After
a 1 second maximum diagnostic period, the spark will
start and the pilot valve will turn on, starting with the trial
for ignition period.
During the trial for ignition period, the control sparks for 4
seconds while rapidly flashing LED. It then turns off the
spark and LED for 1 second while checking pilot flame
sense. This cycle will repeat until pilot flame is detected or
trial time is over.
When pilot flame is detected, the spark will stop, main
valve will turn on and the LED will stay on continuously.
The control will remain in this state until the pilot flame is
lost or the call for heat ends. If pilot flame is lost, LED,
main and pilot valves are turned off for 0.5 seconds and a
new trial for ignition sequence will start.
If pilot flame is not detected during the trial for ignition
period, the pilot valve will be shut off. Lockout will occur if
your model has no retry. For models with retry, the control
will wait for 5 minutes and then begin another
trial-for-ignition sequence.

Troubleshooting

If the system does not function properly, determine the
cause using the procedures in this section.
Before proceeding with troubleshooting the system, check
the following.
Preliminary Checks
Are you using resistive wire between the module
spark (10) and the pilot connection?
Are all mechanical and electrical connections tight?
Is the system wired and ground correctly?
Is gas inlet pressure per manufacturer's
specifications?
Is the system powered?
Is the thermostat calling for heat?
!
WARNING: Risk of Personal Injury.
Do not place face, hands, or other parts of the body in
or near the burner area when the LED is flashing
(recycle mode). When the LED is flashing, the control
may at any time (while in the recycle mode) re-energize
the burner control system and ignite the burner which
may result in electric shock from contact with the
electrode or severe burn injury from firing of the burner.
