INSTALLATION

The Home Generator System unit has been factory

set to run on natural gas. If you need to change from natural gas to LP gas, the unit will need to be reconfigured, as described on page 18.

It is recommended that the fuel connection incorporate the following components:

•A manual fuel shut-off valve located in the interior of the building.

•A manual fuel shut-off valve located outside the building, just before the generator unit.

•Where the formation of hydrates or ice is known to occur, piping should be protected against freezing.The termination of hard piping should include a sediment trap where condensate is not likely to freeze.

•A manometer port should be provided.

The manometer port permits temporary installation of a manometer (Figure 5), to ensure that the engine receives the correct fuel pressure to operate efficiently throughout its operating range.

Figure 5 — Temporary Manometer Installed

When the initial test runs are completed, the manometer is removed and the port is plugged. A typical final fuel connection assembly is shown in Figure 6.
