Refer to the Proper Piping Practice drawing for the general layout at the unit. The following rules apply:

1.Use black iron pipe and fittings for the supply piping. The use of a flex connector and/or copper piping is permitted as long as it is in agreement with local codes.

2.Use pipe joint compound on male threads only. Pipe joint compound must be resistant to the action of the fuel used.

3.Use ground joint unions.

4.Install a drip leg to trap dirt and moisture before it can enter the gas valve. The drip leg must be a minimum of three inches long.

5.Use two pipe wrenches when making connection to the gas valve to keep it from turning.

6.Install a manual shut-off valve in a convenient location (within six feet of unit) between the meter and the unit.

7.Tighten all joints securely.

8.The unit must be connected to the building piping by one of the following methods:

•Rigid metallic pipe and fittings

•Semirigid metallic tubing and metallic fittings (Aluminum alloy tubing must not be used in exterior locations)

•Listed gas appliance connectors used in accordance with the terms of their listing that are completely in the same room as the equipment

•In the prior two methods above the connector or tubing must be protected from physical and thermal damage. Aluminum alloy tubing and connectors must be coated to protect against external corrosion when in contact with masonry, plaster or insulation or are subject to repeated wettings by liquids (water - not rain water, detergents or sewage).
