Commercial Service Line Specifications

Natural Gas Service Line Specifications

Customer service line installation – 2 inch commercial.

Material Specifications


2 inch ASTM 2513 PE 3408 plastic high density polyethylene pipe (black) or PE 2406 plastic medium density polyethylene pipe (yellow), SDR 11 wall thickness. CERC currently installs both within its system. Your service representative will inform you which density is correct.


2 inch PE 3408 high density plastic or PE 2406 medium density plastic ( SDR 11 wall thickness) anode-less riser with approved connection. The riser must be factory assembled.

A wall mounting bracket designed to fasten to the riser and building wall (minimum 6 inch clearance) shall be installed to support the meter manifold.

Tracer Wire

Number 12 solid copper conductive wire with protective coating.

Meter & Pressure Regulating Manifold or Setting

Designed and supplied by company for member requirements. Member or Builder will be responsible for cost of the meter Prefab. (minus the cost of the meter). Installation is the responsibility of the builder and shall be securely installed in an accessible location.

Installation Requirements


The service line shall be installed in compliance with the minimum federal safety requirements established in 49 CFR Part 192 and any other local and company rules. The installer must be Operator Qualified for service line installations, including heat fusion qualification if any will be performed on the service line. Documentation must be supplied to the company. CERC will perform the final connection to main line.

Customer has the option of having the gas company install their portion of the service line at their expense.


The service line shall be installed with a minimum of 24 inches of cover, (preferably 32 to 36 inches deep).


The company requires 3 feet of separation from underground structures running parallel with the service line and a minimum clearance of 12 inches from underground structures crossing perpendicular to the service line. If this clearance cannot be attained, the service line must be protected from damage from the other structure.

Tracer Wire

The tracer wire must be installed in close proximity of the service line and shall terminate above ground at the anode-less riser. The wire should not be taped to or spirally wound around the plastic pipe. Any underground connections in the tracer wire must be protected from corrosion.


The riser shall be installed with an approved wall bracket and shall be terminated above grade at the manufacturers specifications.


A tamper-resistant threaded lock-wing plug valve will be installed on the riser. The valve must have a minimum rating of 100 pounds per square inch gauge (psig). An approved gas service valve shall be installed directly after the meter on the customers piping.

Special Conditions

If the rise terminates above ground in an area with continuous paving to the building wall, an opening around the riser shall be created and backfilled with non-corrosive granular material to allow for venting. When conditions warrant it, protective steel bollards shall be installed around the meter manifold piping to protect it from damage by vehicular traffic.


Whenever possible, the service line shall be a continuous length of pipe with no connections. Connections can be made in the pipe using the heat fusion method by a qualified performer or by using a stab type connection (ex. Perfection perm-a-sert coupling). Metallic compression type couplings are prohibited.


The service line installation must be inspected by company personnel before backfilling. Backfill used around the service line must be clean fill, free of gravel and other debris.


The installed service must be tested to a minimum pressure of 150 psig and verified by company personnel.
