Before starting normal operation of the boiler and heating system, perform the following final installa- tion procedures:

•Leak-check the flue/combustion air system to minimize the likelihood of leakage.

•Leak-check the entire water system, repairing any leaks that may be found.

•Fill the entire water system with water, treated as desired for the application, including anti-

freeze solution if appropriate. Open any shut- off valves in the system.

•Fill the condensate drain trap with water.

•Leak-check the fuel oil supply system and open any fuel shut-off valves.

•Re-check the power and control circuit con- nections THEN replace all cabinet access pa- nels.

•Energize the electrical power circuit to the unit.

After completing the pre-start final system checks, the system can be started and run through start-up checks and adjustments as required.

To start the boiler, first make sure the room ther- mostat is set at a high enough temperature to be closed so that any external water circulating pumps are running. Turn the boiler On-off switch to the "ON" position, and set the Boiler Temperature Con- trol thermostat to its maximum temperature setting.

Turn the Summer-winter switch to "WINTER". This will start the internal circulating pump. After the start time delay set on the oil burner (for the oil heater)

has expired, the burner will start.

Reduce the Boiler Temperature Control thermostat setting to make sure the boiler stops properly when controlled by that thermostat. Increase the room temperature thermostat setting to make sure that the circulating pump(s) stop properly.
