ALL AIR ADJUSTMENTS MUST BE DONE BY A QUALIFIED SERVICE TECHNICIAN
SETTING FIRING RATES
1.) Choose BTU required and fuel supplied. For example 343,000 BTU and Natural Gas.
2.) Adjust the draft or breech pressure to the recommended setting (4.0).
3.) Check nameplate for recommended air setting. A 5.5/0 air setting is recommended.
4.) Measure the carbon monoxide level and adjust air settings, if necessary, to regulate it to about 50 PPM for a
staring point.
5.) Measure the O2 or CO2 at the 50 PPM level. For example, assume the O2 is 1.5% (11% CO2).
6.) Open the air adjustment until the O2 level is increased to 3% O2. This should reduce the CO level and provide
a margin of reserve air to accommodate variable conditions.
7.) Sample the CO level again. It should be in the 0 to 20 PPM range—0 according to settings.
8.) Check the draft to ensure it still meets specifications. If a major change in draft is required, repeat the above
steps.
9.) Perform any final adjustments and lock the air settings securely. Run the burner through several cycles to
verify prompt ignition and stable burner operation.
Repeat same procedure for all other firing rates
