IAQH-1000 Manual
14. Excess Air Adjustment:
a. If the burner is operated at any firing rate lower than maximum capacity,
there is a possibility to have too much excess air.
i. To increase excess air, loosen the nut on the air orifice plate and
slide it outward.
ii. To decrease the excess air slide the air orifice plate inward.
iii. Be sure to tighten the nut on the plate.
15. Final Check:
a. Check the operation of the burner: start and stop several times to check
control.
b. With the burner running, check operation of all limit controls.
c. Perform the following final adjustments for combustion and flue gas
temperature:
i. Take flue gas samples and temperature immediately upstream
of the draft control. The temperature should be above 450 °F
but not exceed 650 °F. NOTE: excessive flue gas temperatures
will result in low efficiencies. Low temperatures can result in
excessive condensation.
ii. Reduce gas input as necessary to adjust flue temperature.
