Vitodens 100-W, B1HA series & B1KA Combi Installation/Service

Mechanical Room

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 66 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). h
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.
WARNING
If you notice fire coming from the appliance, call the
fire department immediately! Do not attempt to
extinguish the fire unless qualified to do so.
WARNING
Fire causes a risk of burns and explosion!
Shut down the boiler
 
Close fuel shut-off valves
 
Use a tested fire extinguisher, class ABC.
 
WARNING
Incorrect ambient conditions can lead to damage to
the heating system and put safe operation at risk.
Installation area conditions
Ensure ambient temperatures are higher than 32°F

(0°C) and lower than 104°F (40°C).
Prevent the air from becoming contaminated by

halogenated hydrocarbons (e.g. as contained in
paint solvents or cleaning fluids) and excessive dust
(e.g. through grinding or polishing work).
Combustion air for the heating process, and ventilation
of the boiler room must be free of corrosive
contaminants. To that end, any boiler must be installed
in an area that has no chemical exposure. The list
below indicates the main, currently known sources.
Avoid continuously high levels of humidity

(e.g. through frequent drying of laundry).
Never close existing ventilation openings.

Sources of combustion and ventilation air contaminants.
Areas likely to contain contaminants:
- New building construction
- Swimming pools
- Remodelling areas, hobby rooms
- Garages with workshops
- Furniture refinishing areas
- Dry cleaning/laundry areas and establishments
- Auto body shops
- Refrigeration repair shops
- Metal fabrication plants
- Plastic manufacturing plants
- Photo processing plants
- Beauty salons
Products containing contaminants:
- Chlorine-type bleaches, detergents and cleaning
solvents found in household laundry rooms
- Paint and varnish removers
- Hydrochloric acid, muriatic acid
- Chlorine-based swimming pool chemicals
- Spray cans containing chlorofluorocarbons
- Chlorinated waxes and cleaners
- Cements and glues
- Refrigerant leaks
- Calcium chloride used for thawing
- Sodium chloride used for water softening salt
- Permanent wave solutions
- Adhesives used to fasten building products and other
similar items
- Antistatic fabric softeners used in clothes dryers
Before set-up
Before placing boiler in its installation location, ensure all
necessary accessories are installed.
CAUTION
The boiler must be installed in such a way that gas ignition
system components are protected from water (spraying,
splashing, etc.) during boiler operation and service.
