Vitocrossal 200, CM2-400, -500 and -620 Technical Data
(continued)
Combustion air supply
The boiler must not be located in areas or rooms where
chemicals containing chlorine, bromine, fluorine, or other
corrosive chemicals are stored. Examples include bleach,
refrigerants, paint, paint thinner, hair spray, cleaning
solvents, water softener salt, etc. The combustion air
must not be contaminated with any amount of the above
mentioned chemicals.
Boiler should never be installed in areas where excessive
dust, high humidity, or risk of frost exist. Ensure adequate
ventilation and supply of fresh combustion air.
Consult your local Viessmann sales representative with
uncertainties in regard to a suitable boiler installation
location.
This boiler/burner unit needs clean fresh air for safe
operation. Provisions for combustion and ventilation air
must be made at time of installation. For gas or propane
installations, use the "Natural Gas Installation Code CAN/
CSA-B149.1 or B149.2" (Canada), or "National Fuel Gas
Code ANSI Z223.1" (USA), and/or provisions of local codes.
The sizing methods outlined in the aforementioned codes
should be used when installing a round duct to supply
combustion air from the outside.
System layout
The boiler water temperature limit is factory set to
167° F (75° C).
The boiler water temperature limit can be increased by
altering the adjustable high limit (AHL) to increase the
supply water temperature.
To minimize piping losses of the system, however,
Viessmann recommends that the radiation and domestic
hot water production in the system be designed for a
158° F (70° C) boiler supply water temperature.
Warranty
Our warranty does not cover damages resulting from
the following:
- Operation with contaminated fill and supplementary
feed water
- Operation with contaminated combustion air
- Exposing the boiler to pressures and temperatures
higher than its certified rating
See warranty sheet for details.
