Connect (plug in) the power supply to the proper outlet. Turn the “ON/OFF”
switch to the “ON” position.
III:
After the system has undergone the sequence of events described in Section 3.1
above and when the two safety shut off valves in the main gas line are opened, the
unit will be in regular operating mode.
IV:
The Dungs air pressure switch installed on the side panel of the unit has been
factory set at 0.3” wc. With the unit in operation, measure the exhaust gas pressure
inside the housing at the “T” connection located under the pressure switch.
V: Test Points
¾ Measure gas line pressure upstream of the gas pressure regulator to ensure it is
within the specified range of 8” – 14” wc.
¾ Measure the gas manifold pressure at the test point located adjacent to the
burner’s gas inlet connection port (for exact location please see item #8 on page
4 of the Riello catalogue), ensure it is within the specified 0.2” –3.0” wc.
¾ Measure the manifold air pressure at the test point located on the side of the
burner (please see item #7 on page 4 of the Riello catalogue). Ensure this
pressure is between 0.4” – 1.4” wc.
WARNING
The gas manifold pressure should not exceed the maximum value
shown on the unit’s nameplate.
