Mechanical Room - Viessmann VITODENS 100-W WB1B Series Installation And Service Instructions Manual

General Information

Mechanical Room

10
During the early stages of new home design, we recommend that proper
consideration be given to constructing a separate mechanical room dedicated to
gas- or oil-fired equipment including domestic hot water storage tanks.
The boiler must be located in a heated indoor space, near a floor drain, and as
close as possible to the wall.
Whenever possible, install boiler near an outside wall so that it is easy to duct
the venting system to the boiler.
Locate boiler on walls capable of supporting the weight of the boiler filled
with water (see section entitled "Technical Data" on page 75 for information
required for total boiler weight calculation). Ensure that boiler location does not
interfere with proper circulation of combustion and ventilation air of other fuel
burning equipment (if applicable) within the mechanical room.
The maximum room temperature of the mechanical room where the boiler is
located must not exceed 104° F / 40° C.
IMPORTANT
Boiler operation in marine
environments (damp, salty coastal
areas):
The service life of the boiler's
exposed metallic surfaces, such as
the casing and fan housing, is directly
influenced by proximity to damp and
salty marine environments. In such
areas, higher concentration levels of
chlorides from sea spray, coupled
with relative humidity, can lead to
degradation of the exposed metallic
surfaces mentioned above. Therefore,
it is imperative that boilers installed
in such environments not be installed
using direct vent systems which
draw outdoor air for combustion.
Such boilers must be installed using
room air dependent vent systems;
i.e. using room air for combustion.
The indoor air will have a much lower
relative humidity and, hence, potential
corrosion will be minimized.
