requirements below are understood and fulfilled (including detailed information found in manual subsections).
Each of the following issues is very important and is discussed in detail in the boiler technical literature. Ensure that the installation
complies fully and completely with all requirements set out in the boiler technical literature.
HLicensed professional heating
contractor
The installation, adjustment, service,
and maintenance of this equipment
must be performed by a licensed
professional heating contractor.
"
Please see section
entitled “Important
Regulatory and
Installation
Requirements”.
HProduct documentation
Read all applicable documentation
before commencing installation. Store
documentation near boiler in a readily
accessible location for reference in
the future by service personnel.
"
For a listing of
applicable literature,
please see section
entitled “Important
Regulatory and
Installation Requirements”.
HAdvice to owner
Once the installation work is
complete, the heating contractor must
familiarize the system
operator/ultimate owner with all
equipment, as well as safety
precautions/requirements, shut-down
procedure, and the need for
professional service annually before

HContaminated air
Air contaminated by chemicals can
cause by-products in the combustion
process which are poisonous to
inhabitants and destructive to
Viessmann equipment.
HCarbon monoxide
Improper installation, adjustment,
service and/or maintenance can cause
flue products to flow into living space.
Flue products contain poisonous
carbon monoxide gas.

4. To adjust the initial lift gas pressure
remove sealing cap, exposing the lift
adjustment knob, turn over cap,
adjust knob to “+” to increase the
start pressure and set to approx. 0.7
to 0.9 “w.c. (manifold pressure).
Factory default setting is set to 100%

Burner Set-up - Gas (continued)
Verifying input of gas boilers
Natural gas burners must have gas
input clocked using the gas meter.
Ensure there is no gas flowing through
the meter other than to the gas-fired
boiler being checked. See pages 15 and
16 for gas flow rate and values for time
(in seconds) for clocking gas meter.
Clock at least 10 revolutions on a one
ft
3
gas meter dial and divide time by
10. The value arrived at should be the
same as shown on pages 15 and 16.
If necessary manifold pressure must be
adjusted to make sure burner is firing at
nominal input. Do not exceed gas input
stated on rating plate. Turn adjustment
screw on gas pressure regulator (RV52)
clockwise to increase gas flow and
counterclockwise to decrease gas flow
(as per instructions on the previous
page).
If checking gas input with a manometer
only use manifold pressures given in
manual as a starting point, and use
combustion instruments to ensure safe
and efficient combustion values.
Be sure to turn gas off before attaching
or removing pressure taps. All plugs
removed for the purpose of gas
pressure measurements must be
replaced and leak-tested after
measurements.
Replacement of 24V gas valve
Use only replacement gas valves from
Viessmann Manufacturing. The 24 VAC
Dungs ¾” MVD-LE 207/6 and ½”
MVD-LE 205/6 direct spark valves are
special valves designed to operate at
the low manifold pressures required by
the Riello burner for both natural and
propane gas. Do not use other gas
valve unless specified by Viessmann.
Field measured combustion results
Use the combustion data label packed
with the gas burner to record field
measured combustion results and affix
label to gas burner.

It is necessary to follow all safety
information in the Riello technical
literature as well as all other OEM
component instructions shipped with
this manual. The Viessmann factory
settings are an initial guide to be
verified or changed by the installer
based on field measured combustion
results. The burner settings arrived at
during field measurements may be
different from the generalized
conversion burner settings given in the
Riello technical literature.
5265 665 v2.5
IMPORTANT
Each Riello gas burner has a different
manifold pressure. When replacing a
gas valve a manometer and
instruments measuring combustion
must be used to ensure burner is
operating safely at its designed input.
An overfired burner is unsafe and can
cause severe personal injury or loss
of life if products of combustion are
allowed to enter living space through
incorrect procedures.
WARNING
Checking for a safe concentration of
carbon monoxide (below 50 ppm
air-free) will ensure continual safe
operation of boiler and burner. Annual
maintenance and cleaning as
described in this manual must be
done. Failure to heed this warning
may lead to severe personal injury or
loss of life.

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.
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
2
, stack
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
2
products of
combustion are printed below. These
values are based on average results -
slightly higher or lower values may be
suitable depending on installation
conditions.
Fuel NG LP Oil
CO
2
9.5 to
10.2%
10.0 to
11.5%
11.0 to

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.
