5.0 11.0 Max. 14.0 13.0 If the line pressure falls outside of these limits, find and correct the cause of the problem before proceeding further. c) Connect a manometer to the manifold (outlet) pressure tap on the gas valve (see Figures 24 and 25). d) Read the manifold pressure. It should be set at: Natural Gas LP Gas Manifold Press. (inches w.c.) 3.5 10.0 e) If a manifold pressure adjustment is needed, make the adjustment by turning the regulator (see Figures 24 and 25) screw clockwise to raise the pressure and counter clockwise to reduce the pressure. If a manifold pressure adjustment is made, recheck the line pressure to be certain that it is still within acceptable limits. Replace the cover screw on the regulator. 16) Test thermostat operation while the boiler is running. Turn the thermostat to the lowest setting. Circulator should stop running. 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. Circulator should restart. 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. Circulator should 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 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. 22 20) After the boiler has operated for approximately 30 minutes, check the boiler and heating system piping for leaks.
