Measure Manifold Pressure (Propane Units)

The main burner ori®ces on a propane gas unit are sized for the unit rated input when the manifold pressure reading matches the level speci®ed in Table 5.

Proceed as follows to adjust gas input on a propane gas unit:

1.Turn off gas to unit.

2.Remove pipe plug on manifold (see Fig. 24), then con- nect manometer at this point.

3.Turn on gas to unit.

4.Remove cover screw over regulator adjustment screw on gas valve.

5.Adjust regulator adjustment screw to the correct mani- fold pressure, as speci®ed in Table 5. Turn adjusting screw clockwise to increase manifold pressure, or turn adjusting screw counterclockwise to decrease manifold pressure.

6.Replace cover screw.

7.Turn off gas to unit. Remove manometer from pressure tap. Replace pipe plug on gas valve, then turn on gas to unit. Check for leaks.

D.Check Burner Flame

With burner access panel removed, observe the unit heating operation. Watch the burner ¯ames to see if they are light blue and soft in appearance, and that the ¯ames are approxi- mately the same for each burner. Propane will have blue flame with yellow tips. See Fig. 25. Refer to Maintenance section for information on burner removal.

E. Air¯ow and Temperature Rise

The heating section for each size unit is designed and ap- proved for heating operation within the temperature-rise range stamped on the unit rating plate.

Table 6 shows the approved temperature-rise range for each heating input, and the air delivery cfm at various tempera- ture rises. The heating operation air¯ow must produce a tem- perature rise that falls within the approved range.

Refer to Indoor Air¯ow and Air¯ow Adjustments section on page 35 to adjust heating air¯ow when required.
