• If necessary, adjust the manifold pressure at the gas valve by removing the regulator cap and turning the adjustment screw clockwise to raise the pressure and counterclockwise to reduce the pressure. The manifold pressure must be between 3.2" W.C. and 3.8" W.C. for natural gas and 9.5"W.C. - Page 16 MAIN LIMIT SWITCH The main limit switch is a 1/2" disc designed to shut off the burner gas should the outlet (bonnet) temperature exceed the maximum design outlet air temperature. This switch is not adjustable. check the operation, block the return air flow through the unit temporarily. The limit switch should function and shut the burner gas off within a few minutes.
