PRE / POST-ASSEMBLY CHECKLIST
The following checklist will help ensure proper installation techniques for the PF2200 Burner Management
System, fuel train components, and burner components. This checklist should be consulted before and after
installation, to ensure requirements are met for the installation of the system.
1. Ensure that the BMS is mounted in a safe area for operation. Look for tripping, high heat exposure,
and other potential hazards.
2. Conduct pull tests on terminating wires in the BMS to ensure proper installation.
3. Install tags identifying that electrical seals have not been poured on electrical connectors entering the
PROFIRE BMS.
4. Ensure the Type K temperature inputs wire is used. (Yellow = positive and red = negative).
5. Point to point wiring is a must with temperature inputs wires (no cold junctions). A cold junction can
cause inaccurate temperature readings and therefore, poor temperature performance.
6. Do not hook up shield wires; this should be done in the field if necessary. It is common to terminate
the shield wires to earth ground or ground grid of each vessel skid; however, this can only be done
upon field installation. The temperature inputs are shipped loose and installed on location in the
vessel. The wiring is completed at that time.
7. For flame detection to work correctly, the flame must be in physical contact with both the flame
detection rod and the grounded pilot nozzle. This allows a current path from the flame detection rod
through the flame to ground. When nozzle velocity is high, the flame may not make contact with the
nozzle. This situation is referred to as "poor flame anchoring." To resolve poor flame anchoring, add a
second grounded Kanthal rod can be placed further in front of the nozzle so that it catches the flame.
