To properly use this chart, find the kW rating of the generator in the left column, and trace to the right. The number to the right is the maximum length (measured in feet / meters) allowed for the pipe sizes on top. The pipe sizes are measured by inside diameter (ID) to include any fittings, valves (must be full flow), elbows, tees or angles. Add 2.5ft. (.76m) per any bend, tee or angle in the pipe to the overall distance. For pressures below 5" of water column (9mm mercury) down to 3.

2. Most applications will require an external manual full flow shutoff valve on the fuel line. *MKYVI { *YPP *PS[ 7LYXSJJ :EPZI 3. When connecting the gas line to the generator, use the provided section of UL Listed or AGA-approved flexible fuel line in accordance with local regulations.

4. Never bend the flexible fuel line to avoid using an elbow. Bending the flexible line decreases its ability to absorb vibrations and defeats its purpose, as well as constricts the actual fuel flow. See Figure 5.5. 5. Check for leaks by spraying all connection points with a soap solution made of dishwashing soap and water. You should not see the solution be “blown away” or form “bubbles”. Next, check the gas pressure at the regulator in the generator by following these steps. – Close gas supply valve.
