Sequence of Operations
1. Reference Instruction Manual 818 for details on the
Veri-Flame control.
2. Turn the BURNER switch on. For modulation units,
the LOW FIRE light on the Veri-Flame comes on.
3. When all externally provided interlocks and limits are
made, the INTERLOCKS CLOSED light on the Veri-
Flame comes on.
4. The Veri-Flame checks that there is no flame signal
and no air switch voltage to panel terminal 10.
5. The Veri-Flame energizes the combustion air motor
(or motor starter), and then checks for combustion air
pressure switch. If it is not made within 10 seconds,
the unit will go to alarm and lockout.
6. For modulation units, the LOW FIRE on the Veri-
Flame turns off and the HIGH FIRE light turns on and
panel terminal 19 makes contact with terminal 20.
This sequence is used to drive an actuator to the
high flow position for rapid purging. The Veri-Flame
checks that the high purge position switch is made.
For purge units, the selected purge timing starts.
7. After the set purge time on modulation units, the
LOW FIRE light comes on, the HIGH FIRE light goes
off, and the contact between terminals 19 and 20 is
opened. This sequence is used to drive the
actuator to the low fire or starting position. The
modulation Veri-Flame checks that the low fire
position switch is made.
8. At the end of the purge time, the spark and the
starting gas valve are energized.
9. The flame on light at the Veri-Flame FLAME SIGNAL
test jack comes on when the sensor detects the
flame. If no flame signal is present at the end of the
trial for ignition, the unit goes to alarm and lockout.
10.At the end of the trial-for-ignition time, the spark is
shut off and the burner flame is held at the start
position to check for flame stability.
11.If the flame signal is still good, the BURNER ON
control panel light turns on. For pilot burner systems,
the main gas valve comes on. The LF relay is
energized to make contact between panel terminals
21 and 23. For purge and no-purge units, this
sequence allows the automatic control of the
actuator for burner firing rate. On modulation units,
the LOW FIRE light turns off and the AUTO light
comes on, allowing the actuator to respond to a
control signal.
12.On units with the alarm beeper, the alarm will come
on for any lockout condition such as loss of flame,
loss of air switch, and loss of gas valve closed switch
during standby mode. There is no alarm for loss of
operating limits and interlocks.
13.To shutdown, turn the burner switch to off or open
any interlock and limit that feeds terminal 7.
