1. 5)The appliance connector must be installed before the sediment trap, if there is one.

  2. 6)Do not reuse a gas connector. Use a new connector for an appliance replacement.

  3. 7)A shut-off valve must be installed before the gas connector. The photo below shows a shut-off valve incorrectly installed after the connector.

  4. 8)Gas appliance connectors should be used in accessible locations only, where the entire connector is readily visible. Do not conceal the connector or run it through walls, partitions, floors or appliance panels. The gas connector pipe runs inside a furnace cabinet in the photo below, which is not allowed.

    Also, the gas connectors come in diameters for low, medium, and high demand appliances. Make sure you get the right size to avoid restricting the appliance’s gas flow. The length of the connector for larger appliances may be restricted to three feet by the local building department.

Here’s a more extensive list of the installation safety standards set by the manufacturer Dormont below.

    One final note: the gas appliance connector should not be installed where it can be easily damaged. In the photo below, the door to the utility room swings up against the appliance connector each time it is opened.

While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
