11. LIGHTING INSTRUCTIONS – TYPICAL

A. TO LIGHT THE BOILER

B. TO SHUT DOWN THE BOILER

1.These instructions apply only to typical standard control systems (HSP System only). Use the Lighting Instructions supplied with the boiler to be sure they apply to the actual control system used.

1.Open main line power disconnect switch to boiler.

2.Close Main and Pilot gas shut-off valves.

2.Set Operating Control to lowest position.

3.Open main line power disconnect switch to boiler.

4.Close Main and Pilot gas shut-off valves.

5.Wait at least five (5) minutes.

6.With Main gas shut-off valve(s) closed, open Pilot gas shut-off valve.

7.Light standing (manual) pilots by depressing the red indicator button on the thermopilot valve. Manually light the pilot and hold the red button long enough for the thermocouple to heat up.

8.Open Main Gas shut-off valve.

9.Set Operating Control to desired setting.

10.Close main line power disconnect switch to boiler.

11.If all limit switches are closed, the spark pilot(s) will light, main gas valves will open and main burners will light.

12.The burners will continue to fire until the Operating Control is satisfied.

C.PILOT FLAME FAILURE

1.If flame signal is lost at pilot, the ignition control will shut off the main gas valves and start sparking within 0.8 seconds.

2.The control will continue to spark for 15 seconds.

3.If a flame is not sensed, the control will shut down the pilot gas valve and wait 5 to 6 minutes.

4.It will then start sparking and open the pilot gas valve for another 15-second ignition trial.

5.The control will continue this sequence indefinitely.

6.Refer to Control Envelope supplied with the boiler for the specific system used.

7.Should a flame failure occur, causing a shut down of the main burners, turn off all electric power to the boiler and close Main and Pilot manual shut-off valves. Call a qualified service technician to inspect the boiler and correct the problem.
