36 gized by a 120 V AC signal from S-1 on the ignition module for approximately 30 seconds. (The hot surface igniter must draw greater than 3.1 amps while being energized or ignition lockout will occur after three tries.
37 9. 24 V AC is applied to the blue power light located on the status display board. 10. 24 V AC is also applied to the red LED safety shut- down light on the front status board until the safeties have been proven. 1 1. 24 V AC is applied to the alarm circuit (optional).
38 36. After proper air pressure is received in the air plenum, the air pressure switches will close. 37. If there is insufficient air pressure and the air pres- sure switch does not close, a 24 V AC signal is sent to the Universal Diagnostics Board to indicate the fault.
39 60. If ignition module two locks out, a signal will be sent to the Universal Diagnostics Board and to the status display board to indicate an ignition fault. 61. The coil of relay K-5 (N.O.) is now energized with the (K-5) contacts closing downstream of the stage 4 connections.
40 23. When a CFH occurs, a 24 V AC signal is sent to the CFH light on the status panel located on the lower left front of the control compartment. 24. Power is also sent from pin 2 of the stage 1 con- nection to pin P1-3 of the universal diagnostic board.
41 49. When power is sent to gas valve 1 it is also sent to time delay relay 1 (TD-1) which starts a 5-second countdown. 50. After the 5-second countdown from TD-1 and the internal contacts close, time delay relay 2 (TD-2 ) receives 24 V AC. 51. Gas valve 1a is energized allowing the remainder of stage 1 to fire.
42 Ignition Module When additional heat is needed, the combustion air blower starts to purge air from the combustion cham- ber for about 15 seconds. On proof-of-air flow , the air- proving switch closes and the igniter is energized. T o ensure safe operation, the gas valve cannot open until the igniter is verified.
43 Fig. 35: Operating Control Low W ater Cut-Off (Optional) The low water cut-off automatically shuts down the burner whenever water level drops below the level of the sensing probe. A 5-second time delay prevents premature lockout due to temporary conditions such as power fluctuations or air pockets.
