Combustion analysis
This gas or oil burner requires
combustion measurements to be
performed at the final installation site
by a licensed heating contractor to
verify factory settings, or to be used as
a guide in changing burner settings to
suit 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 gas or 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.
IMPORTANT
When the boiler is fired for the first
time, the ceramic fiber insulation at the
back of the combustion chamber door
will require ½ to 1 hour of firing time to
"cure". An odor may occur during this
time. Final measurements of CO must
be done only after the "cure" is
complete.

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. The expected CO
combustion are printed below. These
values are based on average results -
slightly higher or lower values may be
suitable depending on installation
conditions.

The CO concentration should be as
shown on the Viessmann quality control
burner test results. If the CO
concentration is above 50 ppm, then
measures should be taken to decrease
concentration to a value below 50 ppm.
Steps to be taken include: ensuring
sufficient supply of combustion air,
adjusting air gate settings, ensuring
chimney and vent are correct and meet
safety codes, verifying boiler input and
burner settings, replacing any defective
part on burner, contacting
manufacturer's technical sales
representative for assistance.
