INSTALLATION
3.1 MECHANICAL
The maximum operating temperature for the flame sensor is 302
F (150
C). If the peak ambient
temperature at the location of the sensor exceeds this then cooling will be required. There are three methods
available for cooling: Water-cooling, air-cooling with ambient air, and air-cooling with pressurized air.
Water cooling requires the use of a water cooling coil Part Number sp-566, GE Part Number
353B3490G001. The water-cooling coil requires water at a temperature of 50
F to 135
F (10
C to 57
C) at
a flow rate of 1.0 gpm (3.8 lpm) per sensor. When using water-cooling the flame sensor can be operated to
an ambient temperature of (455
F) 235
C.
Air-cooling with ambient air can be used in installations where the enclosure is cooled with forced air. This
would be typical of LM2500 and LM6000 aircraft engine applications. The air velocity at the sensor must be 5
ft/sec (1.5 m/sec), or greater, at a temperature of 50
F (10
C), or less, above outside ambient. Under these
conditions the sensors will operate at outside ambient temperatures up to 140
F (60
C).
Air-cooling with pressurized air requires the use of Air-Cooling Can. GE Reuter-Stokes Part Number RS-E2-
0259 (GE Part Number 07482SOCNL44821P01). The Air-Cooing Can is installed in the same manner as the
water-cooling coil. The Air-Cooling Can requires 25-psi (170 kPa) minimum at 120
F (49
C) maximum.

INSTRUCTIONS” on the next page. Leave the sensors installed hand tight until after the sensor checkout
described in Section 3.3.
