To adjust regulator:

1.Set thermostat at setting for no call for heat.

2.Turn ®eld-supplied main gas valve to OFF position.

3.Remove 1¤8-in. pipe plug from manifold. Install a water manometer pressure-measuring device.

4.Set main gas valve to ON position.

5.Set thermostat at setting to call for heat.

6.Remove screw cap covering regulator adjustment screw (See Fig. 37).

7.Turn adjustment screw clockwise to increase pressure or counterclockwise to decrease pressure.
