GAS PRESSURE REGULATOR
The gas valve pressure regulator(s) on the boiler are nominally preset at 3.5" W.C. for Natural gas, and 10.5" W.C. for Propane
gas manifold pressure. The pressure at the gas valve outlet tap, measured with a manometer,while in operation should be 3.5
± 0.1" W.C. for Natural gas and 10.5" ± 0.1" W.C. for Propane gas. If an adjustment is needed, turn the adjustment screw
clockwise to increase pressure or counter-clockwise to lower pressure.
