8.Recheck all air vents as described in step 4.
9.Inspect the liquid level in the expansion tank. The system must be full and under normal operating pressure to ensure proper water level in the expansion tank. Ensure that diaphragm type expansion tanks are properly charged and not water logged.
10.Start the boiler according to the operating instructions in this manual. Operate the system, including the pump, boiler and radiation units, for one hour.
11.Recheck the water level in the expansion tank. If it exceeds half the tank volume, open the tank to reduce the water level. Recheck pressure charge on diaphragm type tanks.
12.Shut down the entire system and vent all radiation units and high points in the system.
13.Close the water makeup valve and check the strainer and pressure reducing valve for sediment or debris. Reopen the water makeup valve.
14.Verify system pressure with the boiler pressure gauge before beginning regular operation.
15.Within three days of startup, recheck and bleed all air vents and the expansion tank using these instructions.
WATER TREATMENT
In hard water areas, water treatment should be used to reduce the introduction of minerals to the system. Minerals in the water can collect in the heat exchanger tubes and cause noise on operation. Excessive build up of minerals in the heat exchanger can cause a
