If no adjustment is required, proceed to Step 8.
If an adjustment is required, proceed to Step 7.
Step 7 - High Fire Manifold Pressure Adjustment Heat
Section 2
Remove the cap from the high fire adjustment screw on
the two stage valve. Adjust the pressure setting by turning
the regulator screw IN (clockwise) to increase pressure.
Turn the regulator screw OUT (counterclockwise) to
decrease pressure. Replace the cap. Cycle the burner by
turning the value of the Stg 3 field OFF and ON to actuate
the valve.
Recheck the manifold pressure and repeat Step 7 if
required. If the pressure reading is correct, proceed to
Step 8.
Step 8 - Low Fire Manifold Pressure Reading Heat
Section 2
Set the Value for Stg 3 to OFF. Using the manometer,
measure the pressure on low fire for heat section 2.
Check the pressure with the chart shown below.
Normally adjustments to the factory settings should
not be necessary.
If no adjustment is required, proceed to Step 10.
If an adjustment is required, proceed to Step 9.
Step 9 - Low Fire Manifold Pressure Adjustment Heat
Section 2
Remove the cap from the low fire adjustment screw on the
two stage valve. Adjust the pressure setting by turning the
regulator screw IN (clockwise) to increase pressure. Turn
the regulator screw OUT (counterclockwise) to decrease
pressure. Replace the cap. Cycle the burner by turning
the value of the Stg 2 field OFF and ON to actuate the
valve.
Recheck the manifold pressure and repeat Step 9 if
required. If the pressure reading is correct, proceed to
Step 10.
Step 10 - Close the manual valve. Remove the
manometer. Check for a leak at the pressure taps using a
leak-detecting solution.
If further unit component testing is required proceed with
the instructions in paragraph 10.3 for the remaining test
mode menu screens. If further unit testing is not required,
press the enter key in succession until the cursor is
flashing in the uppermost left hand corner of screen
E.a.5 and use the up arrow key to navigate to Test Mode
Screen E.a.1. Press the enter key to select the Enable:
field. Press the down arrow key to set the value to OFF.
