Wiring Base
Mount the wiring base on the burner or on a panel. The location should be free from excessive vibra-
tion and within the specified ambient temperature rating. The base may be mounted in any angular
position.
All wiring should comply with applicable electrical codes, regulations and local ordinances. Use
moisture resistant wire suitable for at least 90 degrees C. Good electrical wiring practice should be
followed to ensure an adequate ground system. Refer to Fireye Service Note SN-100 separately and
General Grounding Rules later in this document for grounding methods.
A good ground system should be provided to minimize the effects of AC quality problems. A prop-
erly designed ground system meeting all the safety requirements will ensure that any AC voltage
quality problems, such as spikes, surges and impulses have a low impedance path to ground. A low
impedance path to ground is required to ensure that large currents involved with any surge voltages
will follow the desired path in preference to alternative paths, where extensive damage may occur to
equipment.
Circuit recommendations are found on pages 33 through 38. Consult the factory for assistance with
non-standard applications.

CAUTION: The UV1, UV2, UV8A, UV90 and 45UV3 ultra-violet flame scanners and associ-
ated amplifier modules are non self-checking UV systems and should be applied only to
burners that cycle often (e.g.: a minimum of once per 12 hours) in order for the safety check-
ing circuit to be exercised. If component checking is required during burner operation for
constantly fired burners, utilize the self-checking ultra-violet flame scanners (45UV5) with
associated amplifier module (MEUVS1, MEUVS4) or the infrared flame scanner (48PT2)
with associated AutoCheck amplifier (MEIR1, MEIR4).
WARNING: Installer must be trained and qualified. Follow the burner manufacturers
instructions, if supplied. Otherwise, proceed as follows:
