Eclipse Veri-Flame Instruction Manual 818-2/02
For modulation models: This feature is enabled when the jumper on the
base is cut. The system checks that the high fire position switch and the
main valve closed switch are both made at the end of the high fire purge.
For all models: when selected, the Veri-Flame will restart the sequence after
flame or air failure. The recycle mode allows the system to re-initiate the start-
up sequence automatically provided the main burner has been operating for
at least 35 seconds. If the pilot flame fails to light during recycling, the system
will lock out and annunciate a pilot flame fail. If the recycle is successful and
the main burner is operational for at least 35 seconds, the system is ready for
another recycle. At no time will the system recycle in the event of pilot flame
fail.
For all models: this mode is entered by depressing the TEST/RESET button on
the front cover. In the pilot test mode, the Veri-Flame will hold the sequence once
the pilot flame is established (i.e., the main valve is not energized). When in the
pilot test mode, the green “Interlocks Closed” light blinks.
To exit the pilot test mode, simply push the TEST/RESET button again and the
Veri-Flame will exit the pilot test mode (the green “Interlocks Closed” light
stops blinking but remains lit) and restart the sequence.

For all models: pilot mode is selected using the DIP switch SW2. An inter-
rupted pilot shuts off 10 seconds after the main valve opens. An intermittent
pilot continues during the entire main flame firing cycle.
For purge and modulation models: post purge is enabled by DIP switch
SW8. A post purge maintains the combustion air fan output for 15 seconds
after the interlocks and limit switch input have opened.
For all models: during the trial for ignition period (TFI), the pilot valve and
ignition coil remains energized. At the end of the TFI, the pilot flame remains
on and the ignition coil is de-energized. After a five second delay to prove the
pilot flame, the main gas valve is energized.
A system error (illuminated by the red “System Error” LED on the front cover)
prevents gas ignition. The unit will continue its sequence after the error is cleared.
A lockout condition energizes the alarm output and de-energizes the gas valve
and ignition outputs. The unit must be reset to clear the alarm and start the
sequence. To reset, the button must be pressed twice so that the button is in
the out position.

System Errors &
Lockout Conditions
Post Purge
The following system errors result in immediate lockout conditions:
1) Wiring error which puts external voltage on the output terminals (for
all models).
2) Welded internal contacts or other malfunctions in the Veri-Flame (for all
models).
3) Main fuel valve (for all models)–open after cycle shutdown or before
start-up. The system error light blinks twice and then remains on. The
fan output terminal 8 will energize.
