LOW PRESSURE PROPANE OR NATURAL GAS FUEL CONTROLLER FOR SMALL ENGINES MANUAL PRIMER

The C-039-122 Garretson - Impco Replacement KN is a secondary, automatic zero regulator (with manual primer) is designed for maximum sensitivity and simple, trouble free operation. It is suitable for use with low pressure, Natural Gas and LPG Vapor fuels, where dependable starting is required. Because of its extreme sensitivity, the KN offers excellent results in most remote starting applications if installed and maintained properly. Suitable for LP engines up to 30 kW (40 hp) and NG engines up to 22.37kW (30hp). The engine creates a vacuum which acts through the outlet of the regulator on the diaphragm. Atmospheric pressure then forces the diaphragm toward the vacuum, depressing the lever and pulling the valve seat away from the orifice which allows fuel to flow as long as the demand persists. When the vacuum ceases, a spring force pushes on the lever and forces the seat valve against the orifice shutting off the fuel flow. Due to the sensitivity of the C-039-122, most installations do not need priming to start unless low cranking speed or restricted and lengthy piping are required.
