SPECIAL NOTES ON OPERATION
An important safety feature of the FLAME-MONITOR system is its ability to remember the proper
timed operation of critical terminals such as fuel valve terminals 5, 6 & 7. Jumpering these terminals
could cause the control to sense an unusual condition and lock out.
When changing fuels on combination burners where direct spark ignition is used, it is normal to
jumper terminal 6 to 7. To assure that burner operation is not interrupted in this situation, you must
do one of the following:
• Momentarily interrupt the power to L1 when changing fuels, before the initial burner cycle with
the new fuel, or
• Install a time delay relay as shown in the diagram; this procedure can only be done with CODE
12 or higher programmers.
