Follow EGH Manual instructions for Final Adjustments, Section VII, including filling the boiler and skimming steam boilers. Skimming the boiler as described in Section VII of the EGH Manual requires firing the boiler. Always follow boiler Operating instructions, Figure 11, when starting the boiler. Failure to do so could result in severe personal injury, death or substantial property damage. 2. Inspect base insulation as instructed in Section VII of the EGH Manual. To place boiler in operation: 1. Follow Operating instructions, Figure 11, to start boiler. 2. If boiler starts correctly, proceed with Check-out procedure, Section VIII of this Supplement. 3. If boiler fails to start, check: . Loose connection or blown fuse? o Limit setting below boiler water temperature or steam pressure? o Thermostat below room temperature? . Manual reset device needs to be reset? . Gas not turned on at meter and boiler? o Incoming natural gas pressure less than 5" W. C.? 4. If above fails to eliminate the trouble, refer to Check-out procedure — troubleshooting in this Supplement, Section VIII.

Failure to do so could result in severe personal injury, death or substantial property damage. 1. Increase setting of room thermostat (or operating control) to call for heat. 2. Vent damper (if provided) will slowly open. When damper is fully open, the ignition control will open pilot gas valve and start spark. Vent damper must be in open position when appliance main burners are operating. If damper is not in open position, flue products will spill into the building, causing severe personal injury or death. 3. If pilot lights and proves within 15 seconds, the ignition control turns off the spark and opens the main gas valve (dual valves in single body). Main burners ignite. If pilot does not light and prove within 15 seconds, the ignition control shuts off pilot gas and spark and waits 5 minutes. It then will retry. If the second ignition attempt fails, the ignition control will lockout and close the alarm contact of the impulse relay. 4. During main burner operation: • The ignition control monitors pilot flame current. If signal is lost, main valve is closed, spark is activated, and the operating sequence returns to step 3. • If power is interrupted, the control system shuts off pilot and main gas valves and restarts at Step 1 when power is restored. 5. Stop the call for heat (lower thermostat or operating control). • Pilot and main gas valves wi...
