GAS PIPING INSTALLATION

NOTE: The shut-off gas cock must be installed outside of the unit and should meet the specifications of all applicable national and local codes.

2.Install a ground union joint downstream of the shut-off cock. This joint must also be installed outside of the unit.

3.Install a drip leg at least six (6) inches in depth next to the union as shown in Figure 14. This drip leg is required to collect any sediment that may be deposited in the line.

4.Before connecting the piping circuit to the unit, bleed the air from the supply line. Then cap or plug the line and test the pressure at the tapped shut-off cock. The pressure reading should not exceed 14 inches water column.

5.Using an appropriate backup wrench on the gas valve inlet boss, connect the gas piping to the unit. Check the completed piping for leaks using a soap and water solution or the equiva- lent.

6.After installation of the gas pipe in the unit, the pipe chase opening should be closed with the filler/barrier plug provided.

MANIFOLD PRESSURE

Check the manifold pressure at the unit gas valve. Do not exceed the recommended pressure shown on the unit nameplate.
