BURNER OPERATION BURNER STARTING (A) - (B) • Operating control closes, the motor starts. The pump 3) draws the fuel from the tank through the piping 1) and pumps it under pressure for delivery. The piston 4) rises and the fuel returns to the tank through the piping 5) - 7). -
Page 14: Final Checks
FINAL CHECKS • Obscure the photocell and switch on the control circuit: the burner should start and then lock-out about after starting. • Illuminate the photocell and switch off 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. -
