PROPANE GAS Combustion Calibration -
Continued
13.
Check that the gas pressure downstream of the SSOV is within the range listed below. If
gas pressure adjustment is required, remove the brass hex nut on the SSOV actuator (see
Figure 4-4 in the previous section) to access the gas pressure adjustment screw. Slowly
rotate the screw, in approximately 1/4-turn increments, clockwise to reduce the oxygen
level or counterclockwise to increase the oxygen level, as needed, to reach the value listed
below. Allow the combustion analyzer to stabilize following each adjustment.
PROPANE Gas Pressure Range Downstream Of SSOV
Model
Gas Pressure Range
Innovation 600
1.4"-1.6" W.C. (349 – 399 Pa)
Innovation 800
2.2" - 2.4" W.C. (548 – 598 Pa)
Innovation 1060
1.5" - 1.7" W.C. (374 – 423 Pa)
Innovation 1350
1.6" - 1.8" W.C. (399 – 448 Pa)
14.
If it was removed above, replace the brass hex cap on the SSOV.
15.
Compare the oxygen (O
2
)
level, carbon monoxide (CO) and flame strength readings with
the range
shown in step 19, below.
You may need to adjust O
2
% above this range to avoid
combustion tone issues.
16.
Press the
MENU
key on the front panel of the C-More until
COMBUSTION CAL MENU
appears on the display.
17.
Press the ▲ arrow key until
Set Valve Position
reads
100%
, then press the
ENTER
key.
18.
Press the
CHANGE
key and observe that
CAL VOLTAGE 100%
is flashing.
19.
The oxygen level at the 100% valve position should be as shown below. Also, ensure that
the carbon monoxide (CO) and flame strength readings match the value shown in the table
in step 22 below.
20.
If the oxygen level is not within the specified range, adjust the level using the ▲ and ▼
arrow keys. This will adjust the output voltage to the blower motor as indicated on the
display. Press the ▲ arrow key to
increase
the oxygen level or press the down ▼ arrow
key to
decrease
the oxygen level.
21.
Once the oxygen level is within the specified range at 100%, press the
ENTER
key to store
the selected blower output voltage for the 100% valve position. Record all readings on the
Combustion Calibration Sheets provided.
