This section describes the features of the Veri-Flame. It is divided into three
categories: Standard features, Optional features and the LED Indicator Lights on
the front cover. Refer to Figure 5.5 for sequence diagrams.
This input is considered the normal operation control or run input to the
Veri-Flame system. Interlocks are generally pressure or temperature switches
which, when activated, start the burner. Limit switches are generally pressure,
temperature and other switches which, when activated, stop the burner. The
interlocks and limit switches are wired in series. A break in this circuit will shut
the burner down, but will not produce an alarm.
Interlocks and Limit
Switch Input (Terminal 7)
Combustion Air
Switch Input (Terminal 6)
For purge and modulation models: This input is for monitoring the
combustion air switch separately from other interlocks and limits. The Veri-
Flame checks the air ow switch input is open before start-up, closed during
operation, and open again at burner shutdown, thus preventing operation with
an air switch that is defective, maladjusted or jumped. This input has about a 2
second delay to lter out and ignore a momentary interruption.
The input will be proven open before start-up and after shutdown. If the input
is improperly powered before the fan output is energized, the system error
light will blink. The input must de-energize within 30 seconds or the Veri-Flame
will lockout.
After the fan output has energized, the air switch input must be made within 10
seconds. If not proven, then the system will lockout, the alarm output and the
air failure light will come on. However, if the unit has the optional air switch
input hold feature, the sequence is held indenitely without causing a lockout.
When the air switch input is made, then the sequence continues.
If the air switch opens during the main ring cycle, the system will either
lockout or recycle, depending on the DIP switch recycle selection.
Main Fuel Valve Closed
Switch (Terminal V)
Low Fire Start
Purge and No-Purge models: the Veri-Flame can be interlocked with the
main valve closed switch. This feature checks the switch position before start-
up and after shutdown to insure proper valve operation when the jumper on
the base is cut.
For modulation models: when wired, the system checks for the low re
start position prior to light-off.
The following function features are standard on the Veri-Flame models as noted:
