SENSOR INSTALLATION
WARNING: Incorrect sensor installation may cause the sensor to generate a false flame sig-
nal, causing unburned fuel to collect in the combustion chamber. The result can be explo-
sions, injuries and property damage. Be certain that the flame sensor detects only pilot and
main flames, not glowing refractory, burner or ignition parts.
Route sensor wiring a sufficient distance from ignition and other high voltage or high current wiring
to avoid electrical interference. Interference from ground currents, nearby conductors, radio-fre-
quency emitters (wireless devices), and inverter drives can induce false flame signals. Shielded
cables can help reduce interference with the shield connected to ground at the control end only. The
wire type and its capacitance (picofarads or microfarads) to ground may cause low signal problems,
so a grounded shield may decrease the signal due to the cable's internal capacitance. Multiple UV
tube-type sensor leads run together without shielding may interfere or "cross talk", so the shield or
flexible armor must be grounded to prevent this situation. For flame rod sensor runs approximately
100 feet (30 meters) or greater, use Belden P/N 8254-RG62 coax cable. To achieve the maximum
wiring distance, the shield should not be grounded (keep in mind that an underground shield pro-
vides less protection against electrical interference). Depending on field connections, sensor wiring
can be up to 200 feet (61 meters).
Do not ground the shield to terminal GND.
Unshielded sensor wiring must not be run in common with other wires; it must be run in separate-
conduit. Multiple flame sensor wiring must not be run together in a common conduit or wireway.Use
#14 to #18 AWG wire suitable for 90°C (194°F) and 600 volt insulation, and run each pair of leads
in its own shielded cable. Multiple shielded cables can be run in a common conduit.
Flame rods should be used only on gas burners. They accumulate soot on oil burners, causing nui-
sance shutdowns and unsafe operating conditions.
See the burner manufacturer's literature for flame rod mounting location.
Use only Fireye scanner models UV7A4, UV7R4 & UV7SC. Consult the burner manufacturer's
instructions for mounting location.
