vented gas fueled equipment, the installing plum er or gasfitter shall o serve that a hard wired car on monoxide
detector with an alarm and attery ack-up is installed on the floor level where the gas equipment is to e
installed. In addition, the installing plum er or gasfitter shall o serve that a attery operated or hard wired car on
monoxide detector with an alarm is installed on each additional level of the dwelling, uilding or structure served
y the side-wall horizontal vented gas fueled equipment. It shall e the responsi ility of the property owner to
secure the services of qualified licensed professional for the installation of hard-wired car on monoxide detectors.
a. In the event that the side-wall horizontally vented gas fueled equipment is installed in a crawl space or an attic,
the hard-wired car on monoxide detector with alarm and attery ack-up may e installed on the next adjacent
floor level.
. In the event that the requirements of this su division can not e met at the time of completion of installation, the
owner shall have a period of thirty (30) days to comply with the a ove requirements; provided, however, that
during said thirty (30) day period, a attery operated car on monoxide detector with an alarm shall e installed.
2. APPROVED CARBON MONOXIDE DETECTORS. Each car on monoxide detector as required in accordance with
the a ove provisions shall comply with NFPA 720 and e ANSI/UL 2034 listed and IAS certified.
3. SIGNAGE. A metal or plastic identification plate shall e permanently mounted to the exterior of the uilding at a
minimum height of eight (8) feet a ove grade directly in line with the exhaust vent terminal for the horizontally
vented gas fueled heating appliance or equipment. The sign shall read, in print size no less than one-half (1/2) inch
in size, ”GAS VENT DIRECTLY BELOW. KEEP CLEAR OF ALL OBSTRUCTIONS”.
4. INSPECTION. The state or local gas inspector of the side-wall horizontally vented gas fueled equipment shall not
approve the installation unless, upon inspection, the inspector o serves car on monoxide detectors and signage
installed in accordance with the provisions of 248 CMR 5.08(2)(a) 1 through 4.
( ) EXEMPTIONS: The following equipment is exempt from 248 CMR 5.08(2)(a) 1 through 4:
1. The equipment listed in Chapter 10 entitled ”Equipment Not Required To Be Vented” in the most current edition of

Product Information
Natural gas and liquid propane gas-fired wall-mounted condensing heating oiler
for weather-responsive operation in closed loop, forced circulation hot water
heating systems for space heating and domestic hot water (DHW) production.
The Vitodens 200-W, WB2B series oiler comes factory set for operation with
natural gas. For a fuel conversion to liquid propane gas no conversion kit is
required (see page 14).
Boiler model must e selected ased on an accurate heat loss calculation of the
uilding. Ensure oiler model is compati le with connected radiation.
Vitodens 200-W, WB2B series oilers are factory-tested and cali rated. Further
gas valve adjustments are not typically required during field start-up.
Follow the Vitodens Venting System Installation Instructions to vent
this boiler.

Mechanical Room
During the early stages of designing a new home, we recommend that proper consideration e given to constructing a
separate mechanical room dedicated to the gas- or oil-fired heating equipment and domestic hot water storage tank(s).
The oiler must e located in a heated indoor area, near a floor drain, and as close as possi le to a wall. Whenever possi le,
install the oiler near an outside wall so that it is easy to duct the venting system to the oiler.
Locate the oiler on a wall capa le of supporting the weight of the oiler filled with water (see section entitled “Technical
Data” on page 74 for information required for total oiler weight calculation). Ensure that the oiler location does not
interfere with the proper circulation of com ustion and ventilation air of other fuel urning equipment within the mechanical
room (if applica le).
The maximum room temperature of the mechanical room where the oiler is located must not exceed 104ºF / 40ºC.
Installation area conditions
HEnsure am ient temperatures are
higher than 32°F / 0°C and lower
than 104°F / 40°C.
HPrevent the air from ecoming
contaminated y halogenated
hydrocar ons (e.g. as contained in
paint solvents or cleaning fluids) and
excessive dust (e.g. through grinding
or polishing work). Com ustion air for
the heating process, and ventilation
of the oiler room must e free of
corrosive contaminants. To that end,
any oiler must e installed in an area
that has no chemical exposure. The
list to the right indicates the main,
currently known sources.
HAvoid continuously high levels of
humidity (e.g. through frequent
drying of laundry).
HNever close existing ventilation
openings.
Sources of combustion and ventilation
air contaminants
Areas likely to contain contaminants:
HNew uilding construction
HSwimming pools
HRemodelling areas, ho y rooms
HGarages with workshops
HFurniture refinishing areas
HDry cleaning/laundry areas and
esta lishments
HAuto ody shops
HRefrigeration repair shops
HMetal fa rication plants
HPlastic manufacturing plants
HPhoto processing plants
HBeauty salons
Products containing contaminants:
HChlorine-type leaches, detergents
and cleaning solvents found in
household laundry rooms
HPaint and varnish removers
HHydrochloric acid, muriatic acid
HChlorine- ased swimming pool
chemicals
HSpray cans containing
chlorofluorocar ons
HChlorinated waxes and cleaners
HCements and glues
HRefrigerant leaks
HCalcium chloride used for thawing
HSodium chloride used for water
softening salt
HPermanent wave solutions
HAdhesives used to fasten uilding
products and other similar items
HAntistatic fa ric softeners used in
clothes dryers
Boiler operation in marine environments
(damp, salty coastal areas)
The service life of the oiler’s exposed
metallic surfaces, such as the casing
and fan housing, is directly influenced
y 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 a ove. Therefore, it is
imperative that oilers installed in such
environments not e installed using
direct vent systems which draw
outdoor air for com ustion. Such
oilers must e installed using room air
dependent vent systems; i.e. using
room air for com ustion. The indoor air
will have a much lower relative
humidity and, hence, potential
corrosion will e minimized.
5418 911 v1.6
Incorrect ambient conditions can lead
to damage to the heating system and
put safe operation at risk.
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!
