Vitocrossal 200, CM2 400, 500 and 620 Installation
General Information
Mechanical Room
The Vitocrossal 200, CM2 boiler should be located in a
heated indoor space. The boiler should also be located
near a floor drain and as close as possible to the vertical
chimney or vent.
Whenever possible, install boiler near an outside wall so
that it is easy to duct fresh air directly to the boiler area.
Install boiler on flooring capable of supporting the weight
of the boiler filled with water.
Do not use exhaust fans without adding additional
provisions for fresh combustion air (e.g. fresh air fan)
in the boiler room and do not install the Vitocrossal 200
boiler in rooms with refrigeration equipment. This boiler
requires uncontaminated air for safe operation - do not
install where chemicals are stored.
For Retrofit Applications
Before boiler is connected to piping/heating system,
(which have been previously in service) the piping must
be flushed with city pressure water (50-60 psi) to remove
sludge and other contaminates.
Failure to flush out the heating system piping may result
in restricted flow and/or deposits resulting in boiler failure.
This failure is not covered under warranty.
Do not operate when air is polluted with halogenated
hydrocarbons (e.g. as in aerosols, paints, solvents
and cleaning agents)
Prevent very dusty conditions
Prevent high levels of humidity
Prevent freezing and ensure good ventilation.
Otherwise, the system may suffer faults and damage.
