SETTING THE AIR ADJUSTMENT PLATE
A) Regulation of the combustion air flow is made by adjustment of the manual AIR
ADJUSTMENT PLATE (1) after loosening the FIXING SCREWS (2 &3).The initial
setting of the air adjustment plate should be made according to Column 5 in the
Burner Set-up Chart.
B) The proper number on the manual AIR
ADJUSTMENT PLATE (1) should line up
with the SETTING INDICATOR (4) on the
fan housing cover. Once set, the air ad-
justment plate should be secured in place
by tightening SCREWS 2 and 3.
C) The final position of the air adjustment
plate will vary on each installation. Use in-
struments to establish the proper settings
for maximum CO 2 and a smoke reading of
zero.
NOTE: Variations in flue gas, smoke,
CO 2 and temperature readings may be
experienced when the burner cover is put
in place. Therefore, the burner cover
must be in place when making the final
combustion instrument readings, to
ensure proper test results.
