Combustion analysis
This oil burner requires combustion
measurements performed at the final
installation site, using calibrated
combustion equipment, to verify factory
settings, or to be used as a guide in
changing burner settings to suite local
conditions.
Examples of local conditions which
influence combustion results include:
weather conditions, length of horizontal
vent pipe, diameter and height of the
chimney, side wall venting (power
vent), altitude above sea level, quality
and heating value of oil used, maximum
number of other fuel burning appliances
running at the same time. These
conditions affect the burner set-up. The
burner must be adjusted for acceptable
combustion results under local
conditions of the installation.
Combustion measurements (CO
temperature, draft and CO) are taken in
the flue pipe between boiler and
barometric draft regulator before
dilution air (see the installation manual).
Overfire draft is measured at the
combustion chamber observation port
opening. Over-fire draft ranges from 0
to +0.01 "w.c.. Breeching draft is
approximately -0.02 "w.c..
Note: This boiler is approved for
operation with a breeching draft of up
to -0.08 "w.c. (when used without a
barometric draft regulator).
The expected CO
#2-oil is from 11.0% to 13.0%.
