General Warning

Warning! After checking controls by manual readjust- ment, make sure they are always returned to their proper settings.

NEVER attempt to operate a boiler that has failed to pass all the safety checks outlined below.

The boiler is provided with an ignition safety system.

1.Open the faceplate on the control panel. Discon- nect wire # 17 (Lo-Hi-Lo) or # 26 (On-Off) at the terminal block on the control panel. Disconnect- ing this wire disables the main gas valve, ensuring that gas cannot flow during the test.

2.Turn on the circulating water pump. With the natural gas shutoff and secondary shutoff open and the pilot gas cock open, turn the operating temperature control until the boiler cycles “on.”

3.Observe the operation of the boiler. After all the safety limits on gas pressure, water flow, and tem- perature are satisfied, the blower will run and pre- purge the boiler. When air flow is established, the ignition transformer and pilot will operate. Both functions will be indicated by separate green lights on the control panel. If a satisfactory pilot is established, the green "Ignite" light will extin- guish and the pilot will remain on, alone, for 10 seconds. After 10 seconds, the green "Main Gas" light will go on. (The main gas valve will not open with the wire disconnected and gas cannot flow to the burner). The "Pilot" will remain on, along with the "Main Gas," for another 10 seconds and then go out. Since the main flame cannot be burning, at this point there will be no flame signal and the flame safeguard programmer will assume a "Flame Failure" and will either re-cycle through the complete pre-purge and ignition cycle or, if in-

TBIG-03 specifications
