LIGHTING INSTRUCTIONS – TYPICAL
A. TO LIGHT 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.
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.
B. TO SHUT DOWN THE BOILER
1. Open main line power disconnect switch to boiler.
2. Close Main and Pilot gas shut-off valves.
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.
