Step5: Verify Settings Setting verification:

Note:

There are no high fire gas adjustments or air adjustments when

firing into a neutral chamber. However, air and gas

pressures can be used to verify the burner system is

properly adjusted.

1. With burner lit, drive control motor to high fire.

2. Wait for the chamber to reach normal operating

conditions (e.g. chamber temperature, process flows, etc.).

3. Measure high fire fuel differential pressure between tap (B)

and tap (D). Compare this to the “Fuel Orifice ∆P vs.

Input” graph on the data sheet.

4. Measure high fire air differential pressure between tap (C)

and the chamber. Compare this pressure to the “ Air ∆P vs.

Air Flow” graph on the data sheet.

5. Drive the control motor to low fire and verify low fire

flame signal and flame appearance (if viewing).

Note:

Gas pressure at low fire will be too low to measure and

verify the fuel settings.

6. Cycle burner from high to low several times to check

repeatability of settings.

7. R

eadjust burner if the settings do not repeat as excepted. If

necessary, refer to Chapter 5, Maintenance & Troubleshooting.

8. Record all setup data as an aid for future troubleshooting

and setup operations.

Caution:

Do not turn the combustion air blower off until the chamber

temperature is below 250°F (121°C). This will prevent hot

gases from back flowing into the burner and blower causing

damage to the burner.

9. Stop the burner.
