Page 7: Nozzle Assembly
The two nozzles usually have equal deliveries, but the low fire nozzle may have the following specifications if required: • a delivery less than 50% of the total delivery when- ever the back-pressure peak must be reduced at the moment of firing: the burner allows good combustion values also with a ratio 40 - 100 % between low and high fire;... -

Page 10: Burner Calibration
BURNER CALIBRATION FIRING Set switch 1)(C) to "ON". During the first firing, during the switch over from low to the high fire, there is a momentary lowering of the fuel pressure caused by the filling of the high fire noz- zle tubing. -
Page 11: Final Check
FINAL CHECKS • Obscure the photocell and switch on the control devic- es: the burner should start and then lock-out about 5 s after opening of the low fire nozzle operation valve. • Illuminate the photocell and switch on the control cir- cuit: the burner should go into lock-out . -
