3.7 Natural Gas Utility Fuel Hookup, PN-6x-T 7.5kW

These general instructions apply to either remote or collocated systems.

• Connection to the utility fuel line is made using a 3/4" shear point union, 1/2" black iron

pipe, and the appropriate pipe thread sealant suitable for use with natural gas or propane

vapor.

• Use approved pipe thread sealant on all fuel line connections (except flare fittings).

• Thoroughly check the fuel system for vapor leaks. Use an approved leak detector liquid,

or a soap-water solution, with the fuel system pressurized to the cabinet with 0.5 to 1.0

pounds of fuel pressure. Do not use test solutions that contain ammonia or chlorine,

since they prevent soap from bubbling.

• Check and satisfy all local codes before connecting gas to the fuel system.

Observe all safety precautions when working with fuel lines. The illustrations on this page

should be considered for general reference only. Installation should ONLY be done by

qualified personnel. Alpha is not liable for gas leaks resulting from improper installation.
