10.Start the boiler according to the “Start-Up 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 start-up, recheck and bleed all air vents and the expansion tank using these instructions.

FIG. 47 Installation with a Chilled Water System

Pipe refrigeration systems in parallel. Install duct coil downstream at the cooling coil. Where the hot water heating boiler is connected to a heating coil located in the air handling units which may be exposed to refrigeration air circulation, the boiler piping system must be equipped with flow control valves or other automatic means to prevent gravity circulation of the boiler water during the cooling cycle. The coil must be vented at the high point and hot water from the boiler must enter the coil at this point. Due to the fast heating capacity of the boiler, it is not necessary to provide a ductstat to delay circulator operation. Also, omit thermostat flow checks as the boiler is cold when heating thermostat is satisfied. This provides greater economy over maintaining standby heat.
