2.2. Natural Gas Connections

Detailed natural gas connections instructions are covered in Attachment 2 – Section 5 Fuel Conversion/Gas Connections. All pipe sizing, construction, and layout must comply with NFPA 54 for natural gas applications and local code requirements. The three gas meters are to be replaced (ounces to lbs) and regulators installed on the lines to the quarters.

2.2.1. Natural Gas Pipe Sizing

AGA-approved gas pipe is to be tied into the current line. Approximate pipeline distances required are 96’ (Apartment #1), 114’ (Apartment #2) and 119’(House). Correct natural gas pipe size is to be determined using Attachment 2 – Section 5 Fuel Conversion/Gas Connections Table 5-1. All tie-in points will be exposed. Line connections are to be fused and a tracer wire buried with the run. American Meter Company regulators are to be used at the connection point to the house and to the generator. Regulators will be provided.

2.2.2. Fuel Shutoff Valve

The generators will require an external manual fuel shutoff valve on the fuel line. The fuel shutoff valve is to have a manometer port for making fuel pressure checks. The fuel shutoff valve must be installed at a readily accessible location, and within 6 ft of generator fuel inlet.

2.2.3. Flexible Fuel Line

The installation of a flexible fuel line is a gas code requirement. When connecting the flexible fuel line to the generator use a listed assembly meeting the requirements of ANIS Z21.75 – Connections for Outdoor Gas Appliances and Manufactured Homes or AGA-approved flexible fuel line in accordance with local regulations. The flexible fuel line must not be connected directly to the generator fuel inlet. The flexible fuel line must be installed horizontally and must be installed between the fuel shutoff valve and generator fuel inlet. Approved gas fittings must be used. All labels and tags are to remain on the line.

2.2.4. Checking Connections

All installed gaseous fuel piping must be purged, and leak tested prior to initial startup in accordance with local codes, standards, and regulations. Fuel pressure is to be within specifications on the fuel data decal.

2.2.5. Fuel System Leak Test

A final fuel system leak test is to be completed before starting each generator. The entire fuel system is to be tested from supply to regulator by spraying all connection points with a non-corrosive gas leak detection fluid.
