Set Combustion with Test Instruments

1. Allow the burner to run for approximately 5 to 10
minutes.
2. Set the stack or over-fire draft to the level specified
by the equipment manufacturer.
3. Follow these five steps to properly adjust the
burner:
Step 1: Adjust the air band/fuel pressure until a
trace of smoke is achieved.
Step 2: At the trace of smoke level, measure the
CO (or O ). This is the vital reference point for
2 2
further adjustments. Example 13.5% CO
O ).
2
Step 3: Increase the air to reduce the CO
1.5 to 2 percentage points. (O
by approximately 2.0 to 2.7 percentage points.)
Example: Reduce CO
to 5.3% O ).

Step 4: Recheck smoke level. It should be zero.
This procedure provides a margin of reserve air to
accommodate variable conditions. If the draft level
has changed. recheck the smoke and CO2 levels
and readjust burner if necessary.
Step 5: Once the combustion has been set, tighten
the air band locking screw, see Figure 8.
4. Start and stop the burner several times to ensure
satisfactory operation. Test all other equipment
safety controls to verify that they function according
to the manufacturer's specifications.
