Page 17: Flame Signal Measurement
FLAME SIGNAL MEASUREMENT (A) LAL2... Sub-base Min value for a good signal: 8 µA. If the value is lower, it can be due to: • Worn photocell; • Low current; • Bad set up of the burner. In order to measure the current, use a microammeter of 100 A c.c., connected to the scanner, as in the dia- gram. -
Page 18: Final Checks
FINAL CHECKS • Obscure the photocell and switch on the control devices: the burner should start and then lock-out about 5 s after starting. • Illuminate the photocell and switch on the control devices: burner should go into lock-out. • Obscure the photocell while the burner is operating: flame should go out and burner lock out within 1 s. -
Page 19: Opening The Burner
Pump The pump delivery pressure must be stable at 290 PSI. The suction must be less than 6.5 PSI. Unusual noise must not be evident during pump opera- tion. If the pressure is found to be unstable or if the pump runs noisily, the flexible hose must be detached from the line filter and the fuel must be sucked from a tank located near the burner. -

Page 28: Procedure To Refer Burner Operating Condition In High Altitude Plants
APPENDIX - PROCEDURE TO REFER BURNER OPERATING CONDITION IN HIGH ALTITUDE PLANTS Find the corrected burner capacity for the plant’s altitude in chart 1 and the corrected pressure in chart 2. Check in the firing rate graph of the burner (page 7), if the working point defined by the values above is within the range limits. If not, higher burner size is needed.
