Gas meter needing repairsGas Meter Clearance Distances & Specifications

Installation & inspection points for gas meters

Gas meter clearance & piping distances & gas meter dimensions:

This article provides detailed tables of clearance distances for natural gas meter installations, giving the distances to various building features such as windows, doors, electrical components, vents, air conditioners, and outside hose bibs.

Gas service line trench features are also described.

We include examples of typical gas meter overall dimensions for residential as well as commercial gas meters for both LP and natural gas.

In this article series on gas meters, controls & piping, we provide descriptions and photographs of unsafe gas piping, indications of unsafe or improperly operating gas appliances, gas meters, and other gas installation defects.

InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers, products, or services discussed at this website.

Clearance Distances between a Gas Meter or Gas Meter Regulator Vent & Building Components

Article Contents

...

Example1 Gas Meter Clearance Distances from Building Features

Building Feature Minimum Clearance Distance to Gas Meter or Regulator Vent
Gas meter location Front wall (front presumed facing public access), or within 3 feet of side wall (see corner clearances)
Regulator relief vent distance from any outside building corner

12 inches.

With this specification met, there are no clearance distance requirements for building features located around the corner from the gas meter.

If the regulator relief vent is less than 12" from any outside corner, then the minimum clearances specified in this table must be maintained.

Measure as a direct, straight line from the nearest meter set or component to the nearest edge of the building feature "as if using a string"

Notes to the Table Above

1. These are typical gas meter clearance distances to various building features, but keep in mind however that this list is not exhaustive. Local building code requirements for safe distances from a gas meter or gas meter vent vary, depending on where you live, and are also different between the U.S. and Canada. Be sure to check with your local building or plumbing code officials.

Gas Meter Clearance To Sources Of Ignition

 

Electrical equipment that can serve as a source of ignition is defined as an ignition source if it creates an arc or spark during operation.

Normal building electrical wiring and junction boxes are not sources of ignition,

Electrical panels, most electrical switches, relays, and similar controls that can create a spark when operated are considered a "source of ignition".

Electric meters on buildings are not considered a source of ignition.

All portions of a gas utility distribution system up to the outlet of the meter are regulated by 49 CFR Part 192, under the U.S. Department of Transportation.

These regulations require a three-foot clearance from indoor meters to sources of ignition, but have no comparable requirement when the meter is located outdoors.

At least 3 feet, per NEC 110-26 & NFPA 54-National Fuel Gas Code for premises-owned gas meters.

Preferred: 10 feet.

In at least some jurisdictions, the National Fuel Gas Code excludes meters and other equipment used by the gas utility from inclusion within scope of the Code.
