Amana GUI* Installation Instructions Manual page 24

With Power and Gas Off:
1. Honeywell Model VR8205, or White-Rodgers Models
36E36 or 36E22, or Robertshaw Model 7222: Connect
a water manometer or adequate gauge to the "inlet
pressure tap" of the gas valve.
As an alternative method, inlet gas pressure can also
be measured by removing the cap from the drip leg and
installing a predrilled cap with a hose fitting (Figure 37).
With Power and Gas On:
2. Put furnace into heating cycle and turn on all other gas
consuming appliances.
If operating pressures differ from above, make necessary
pressure regulator adjustments, check piping size, etc.,
and/or consult with local utility.

(Alternate Method)
Gas Manifold Pressure Measurement and
Adjustments
NOTE: The gas manifold pressure must be measured with
the burners operating.
Connect a "U-Tube" manometer having a scale range from
0 to 12 inches of water to the tapped opening in the gas
valve (see Figures 36-39 for pressure tap location). Check
your measurements. For natural gas, the manifold pres-
sure must between 3.2 and 3.8 inches water column (3.5
nominal). For propane gas, it must be between 9.7 and 10.3
inches water column (10.0 nominal). Any major changes in
flow should be made by changing the size of the burner
orifice.
If pressure adjustments are necessary, make them in small
variations. To adjust, use the pressure regulator. Remove
the adjustment screw or cover on the gas valve. Turn out
(counterclockwise) to decrease pressure, turn in (clock-
wise) to increase pressure.
