Service

The KN should be periodically checked for leakage past the valve seat and the vents on the cover kept clean and free of obstructions. If the KN needs service we suggest you take it to a qualified serviceman. If that help is not available Garretson will furnish you a list of repair shops with the proper service information.

Installation

The KN should be mounted as close to the carburetor as possible with the arrow on the cover pointing up and the diaphragm in a vertical position. This helps to minimize the effects of gravity on diaphragm travel. This unit should also be placed for easy access to the primer if provided. There are two sets of mounting holes provided. either set of mounts will adequately support the KN. The bottom set of holes has a 1 3/4” bolt spacing for use with all Garretson universal mounting brackets. The mounting bosses on the cover are spaced (5 3/4”) for 5/16 bolts.

Before installing the fuel supply line, be sure that the gas pressure is no more than the maximum inlet pressure shown on the front of the KN. If the pressure is greater, leakage could result in a fire hazard and or hard starting. The piping to the inlet should be of sufficient size to allow full flow to the KN. This is very important in natural gas installations as any restrictions can affect engine performance. If a solenoid is used ahead of the KN in the low− pressure line, it should have an orifice at least as big as the orifice in the KN. Flexible piping to the inlet should be used to prevent cracking from vibration if the KN is mounted on the engine or other vibrating surface.

Note: Thread sealing compound should be used on all pipe thread fittings between the KN and the fuel supply tank, being careful not to get any inside the inlet or fittings. Excess compound could collect on the seat and orifice and cause hazardous leakage, resulting in poor performance. After piping is complete, turn on the gas and use a soap solution to check all fittings for leaks.

If an electric solenoid primer is used, follow the wiring and adjusting instructions furnished separately. kit by connecting into a pressure line at a reduced pressure, call us. The KN outlet is 3/8 NPT and if an outlet fitting has not been provided, select and insert a suitable vapor fitting taking care not to allow any chips or dirt to enter the outlet. Use of street ells or conventional pipe fittings in the fuel line between the KN and the carburetor is not recommended as they may restrict the flow of fuel.

When installation of a properly sized fuel hose between the KN and carburetor is completed, if you are installing a complete conversion return to the instructions. For field replacement applications the unit is ready for service.
