IV. BFIT - Component Identification
1. Communication Interface (Concert Boiler Control
TM
)
The BFIT boiler series is equipped with Concert Boiler Control
TM
display which provides easy access for
viewing and adjusting boiler operational parameters, monitoring historical performance characteristics
and annunciating boiler alarm/lockout conditions.
2. Main boiler control
It receives and Processes input signals from safety switches and sensors to modulate main burner
firing rate.
3. Control box
The control box is designed to allow easy acess to safety components and PCB boards for service and
troubleshooting purposes.
4. ON/OFF switch
The OFF position interrupts power to the unit.
5. Main gas valve
It regulates the flow of gas into the pre-mix burner by sensing negative pressure from the blower.
6. Blower
The blower is designed for pre-mix application and delivers combustion air and gas to the burner at
a desired ratio over the modulation range.
7. Bluejet
R
Burner
The high efficiency, low NOx Bluejet
R
Burner is mounted on the burner door with eight M4 x 10
scews.
8. Ignition electrode
The ionization electrode provides electrical spark for ignition. The ignitor assembly is installed on the
burner door with two M4 x 10 torx screws.
9. Flame inspection
A ¾ inch diameter quartz sight glass provides a means of visual inspection of the burner flame
condition.
10. Thermal fuse
If the temperature at the burner door reaches over 320F, the thermal fuse will interrupt power to the
burner. Used to detect dangerous flame blow back and burner door insulation failure.
11. High gas pressure switch
The high gas pressure switch monitors supply gas pressure and shuts off the electrical control circuit
when pressure rises above the set point (see Table 21).
12. Low gas pressure switch
The low gas pressure switch monitors supply gas pressure and shuts off the electrical control circuit
in the event a low gas pressure condition occurs (see Table 21).
13. Supply water line
Outlet manifold with Victaulic grooved connection conveys supply water from the boiler to the system.
Refer to Table 3 for model specific pipe size.
14. Water flow switch
In the event of insufficent water flow the boiler will be shut down by the action of the flow switch. Refer
to Table 26 for water flow rate requirements.
