Setting GUD/GCD Manifold Pressure

Only small variations in gas flow should be made when adjusting the gas valve pressure regulator. For propane gas,

the manifold pressure must 9.7 to 10.3” W.C.

WARNING

To prevent death or personal injury due to carbon monoxide, all hoses must be connected

as shown in Figure 12. Failure to connect the hose between the pressure switch and the

burner box could result in excessive generation of carbon monoxide.

GUD, GCD Manifold Pressure Measurement

1. Turn OFF gas to the unit at the manual gas shutoff valve.

2. Connect a calibrate “U” tube manometer (or appropriate gas pressure gauge) between the tapped outlet in the gas

manifold and a tee (field-supplied) in the hose from the burner box to the gas valve.

3. Turn ON gas supply and operate unit. NOTE: Burner box cover must be in place.

4. Remove the cover over the manifold pressure regulator screw.

5. Adjust manifold pressure. Turn adjustment screw out (counterclockwise) to decrease pressure. Turn adjustment

screw in (clockwise) to increase pressure.

6. Reinstall the cover over the manifold pressure regulator adjustment screw in order to check manifold pressure.

Make further adjustments if necessary.

7. Turn OFF gas supply to unit and disconnect manometer.

8. Go to “Unit Operation Check and Labelling” section.
