Eclipse Bi-Flame v1.8, Instruction Manual 826, 05/03

In this section, the necessary procedures are detailed to integrate a
Bi-Flame into a burner system; Figure 6.1 (page 25) illustrates the
various terminal strips mentioned.
Note:
Shut off the power supply before any module is removed or
replaced from the unit, including the remote display.
Caution:
Installation and maintenance must conform with the National
Electrical Code and all other national and local codes and authori-
ties having jurisdiction.
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. This input is considered the normal operation
control input to the Bi-Flame system.
This input is for monitoring the combustion air switch separately
from other interlocks and limits. When wired to this input, the air
switch will be proven open before start-up and after shutdown. It
will also be proven closed 10 seconds after the combustion air
blower is energized.
If the air switch opens during the main firing cycle, the system will
either lockout or recycle, depending on the DIP switch selection.
If this terminal is not used, place a jumper between the combustion
blower output (terminal 3 on terminal strip J2) and the air switch
input (terminal 2 on terminal strip J1). This jumper must not be
used in place of a required air flow switch interlock.
If the combustion air blower is controlled outside of the Bi-Flame
system, then the air switch must be wired between the combustion
blower output and the air switch input. Connecting the air switch
in this manner will prevent the open contact (air short) check on
the switch.
