ManualsBrandsFireye ManualsHeating Supplies1" BSP Self-Check Ultra-Violet Flame Scanner with 8 Ft. Leads (120V)

Under normal temperature conditions, with clean burning fuels and moderate ambient temperature

conditions, purge air flow of approximately 4 SCFM (113 L/min) is generally adequate. A 0.1 psig

positive pressure difference between the atmosphere and boiler pressure measured at right angle to the

purge air flow, should result in a purge air flow of 4 SCFM. Up to 15 SCFM (425 L/min) may be

required for fuels that may produce high levels of smoke of soot or for hot environments to maintain

scanner internal temperature within specifications.

NOTE: The maximum viewing field of the lens is one inch per foot. Do not use more than one foot of

one inch sight pipe. Increase sight pipe diameter one inch for every additional foot of sight pipe

length used, to avoid restricting the scanner’s field of view. Temperature in the scanner housing

should not exceed those temperature limits listed in the specifications. Excessive temperatures will

shorten scanner life.

SCANNER WIRING

All FIREYE controls are protected against short-circuited scanner input terminals. Following recom-

mendations apply for scanner-control wiring: The following recommendations apply for scanner con-

trol wiring:

• Keep scanner wiring as short as possible.

• Use wires rated for scanner voltage and its ambient conditions (temperature, humidity, oil resis-

tant, flame retardant, etc.)

• Do not run scanner wires in the same conduit as other electrical wires.
