7.6Appliance Isolation during Gas Supply Piping Pressure Test

1.The appliance and its provided manual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ PSI (3.5 kPa).

2.The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ PSI (3.5 kPa).

3.The appliance and its gas connection must be leak-tested before placing it in operation.

7.7Gas Connection

1.Safe operation of unit requires adequate gas supply with the required static and dynamic (flow) pressures. Actual piping selection depends on many variables that must be carefully considered by the gas piping system designer.

Do not select gas pipe sizes based only on the supplied tables. These tables are for use by the gas piping system designer as a reference in checking pipe size selections.

2.Gas pipe size may be larger than heater connection.

3.Installation of a union is suggested for ease of service.

4.Install a manual main gas shutoff valve, outside of the appliance gas connection and before the appliance provided appliance manual shutoff gas valve, when Codes require.

5.The gas system installer should clearly identify the emergency shut-off device.

6.A sediment trap (drip leg) MUST be provided in the inlet of the gas connection to the unit.

7.The code compliant vent limiters are designed and must respond to pressure changes in the installation environment, as opposed to outdoor pressure. For proper operation, do not connect to outdoor atmosphere.
