16) Test thermostat operation while the boiler is running. Turn the thermostat to the lowest setting. For standing pilot boiler
models, pilot burner should remain lit but the main burners should stop firing. For intermittent ignition boiler models both pilot
burner and main burners should stop firing. Raise the thermostat back to the highest setting. The main burners (for standing
pilot boiler models) or pilot burner and main burners (for intermittent ignition boiler models) should relight.
17) Verify high limit operation. Allow the boiler water temperature to increase to hi limit setting. The burners should shut
down and the circulator continue running. For standing pilot boiler models, pilot burner should remain lit but the main burners
should stop firing. For intermittent ignition boiler models, both the pilot burner and main burners should stop firing.
18) Allow the boiler water temperature to drop below high limit setting.
19) The main burners (for standing pilot boiler models) or pilot burner and main burners (for intermittent ignition boiler
models) should relight.
20) After the boiler has operated for approximately 30 minutes, check the boiler and heating system piping for leaks. Repair any
leaks found at once.
21) Inspect the vent system for flue gas leaks. Repair any leaks found before leaving the boiler in operation.
