INTRODUCTION
This section describes the test procedures that must be performed
after installation to insure that the Bi-Flame is operating properly;
these procedures are mandatory.
Insert the positive probe of a 0-15 VDC, one megohm/volt meter into
the test point on the front cover, as shown in the photo at left. Con-
nect the negative probe to ground. A good flame signal strength will
read between 6 and 11 VDC; anything below 4 VDC is inadequate.
Run the following test procedures to ensure that the sensor will
not detect a pilot flame too small to reliably light the main flame:
1) Manually shut off the fuel supply to the burner, but not to the pi-
lot.
2) Start the system normally.
3) To enter the pilot test mode, press the RESET and ENTER but-
tons simultaneously. Then release the RESET button but keep
the ENTER button depressed for another 10 seconds. The Limits
LED will blink, signalling that the system is in the pilot test mode.
4) The control will hold the operating sequence at the pilot flame
step. Measure signal strength as described above.
5) Reduce pilot fuel until the flame relay drops out. Increase pilot
fuel until the flame signal is greater than 4 VDC, and flame relay
just manages to pull in. This is the minimum pilot. If you don’t
think this flame will be able to safely light the main burner, re-
align the sensor so that it requires a larger pilot flame and re-
peat steps 2 through 5.
6) Push the RESET button to exit the test mode and begin the
normal start-up sequence again.
7) When the sequence reaches the main flame trial for ignition,
smoothly restore the fuel supply to the burner. If the main
burner does not light within five seconds, immediately shut off
the burner supply to shut down the system. Realign the sensor
so that it requires a larger pilot flame. Repeat steps 1 through
6 until the main burner lights off smoothly and reliably.
