Section: Start the Burner

Use test instruments to set combustion:

Always use calibrated test instruments to set combustion

levels. Verify that test instruments are calibrated and in good working condition. If not already provided, drill test access holes in the flue pipe near the breech (or upstream of the boiler breech damper, if applicable) and in the front mounting plate area for firebox pressure. Be careful not to damage any water-backed surface.

Verify that all boiler sections, canopy, and access plates or doors are fully equipped with gaskets and sealed against any leakage, which could affect the combustion test results. Before making these tests, operate the burner for several minutes to allow the heating system temperature to stabilize or nearly reach steady-state levels. Record all results in the start-up log for future reference.

○Draft – Set the breech or furnace pressure to the level specified by the appliance manufacturer. Typical example: +0.10” W. C.

○Oxygen – It is recommended that you measure the oxygen (O2) early in the test sequence because high levels of carbon monoxide can be created at very low or even very high O2 levels. The typical operating range is between 2.5% – 4.5 %. The equivalent carbon dioxide (CO2) operating range is 9% – 10.5%.

High excess air levels reduce the flames UV output and the

scanner signal that proves the burner is firing.

○Carbon monoxide (CO) – An operating range of 0 -50 PPM is recommended for the CG10 burner. The maximum carbon monoxide (CO) level permitted in the flue gas by the UL 795 Standard is 400 PPM (.04%).

○Stack Temperature – The stack temperature should be within the range specified by the appliance manufacturer. It is influenced by input firing rate, flame shape, excess air ratio, and cleanliness of boiler flue passages. This temperature, combined with the ambient temperature, and O2% (or CO2) is used in calculating the appliance efficiency.

Recommended combustion test sequence:

1.Adjust the draft or breech pressure to the appliance manufacturer’s recommended level.

2.Measure the carbon monoxide level and adjust air settings, if necessary, to regulate it to about 50 PPM for a starting point.

3.Measure the O2 or CO2 at the 50 PPM CO level. For this discussion, assume the O2 is 1.5% (11% CO2).

4.Open the air adjustment until the O2 level is increased by at least 1% or to 3% O2 (whichever is higher). This should reduce the CO level and provide a margin of reserve air to accommodate variable conditions.

5.Sample the CO level again. It should be in the 0 to 20 PPM range.

6.Check the draft to ensure it still meets specifications. If a major change in draft is required, repeat the above steps.

7.Perform any final adjustments and lock the air settings securely. Run the burner through several cycles to verify prompt ignition and stable burner operation.
