Installation Manual

•Piping must be of the correct size to maintain the required supply pressures and volume flow under varying conditions.

•Use an approved pipe sealant or joint compound on all threaded fittings to reduce the possibility of leakage.

•Installed piping must be properly purged and leak tested, in accordance with applicable codes and standards.

Consider the following factors when planning to install the fuel supply system:

The Home Standby Generator engine is fitted with a fuel mixer system that meets the specifications of the California Air Resources Board for “tamper-proof” dual fuel systems. The unit will run on natural gas or liquefied propane.

•A minimum of one manual shutoff valve should be placed in the fuel supply line and located outside the building to facilitate servicing the generator.

•Natural gas fuel supply pressure at the generator's fuel inlet port should be between 5 to 7 inches of water (in. W.C.) at full load. LP fuel supply pressure should be 11 to 14 inches of water (in.W.C.) at full load.

The Home Standby Generator 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 13.

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.

•The termination of hard piping should include a sediment trap.

•A manometer port should be provided.

WARNING

Propane and Natural Gas is extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

•Before placing the Home Standby Generator into service, the fuel system lines must be properly purged and leak tested.

•NO leakage is permitted.

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.

NOTE: A digital manometer, P/N 19495, is available at your local Briggs and Stratton Power Products service center.

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.
