Setting The Air Adjustment Plate; Burner Set-Up Chart - Riello 40 Installation & Operating Manual

SETTING THE AIR ADJUSTMENT PLATE

A) Regulation of the combustion air flow is made by adjustment
of the manual AIR ADJUSTMENT PLATE
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 adjustment 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 instruments to establish the proper settings
for maximum CO and a smoke reading of zero.

NOTE:
Variations in flue gas, smoke, CO
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.
