Safety, Installation and Warranty Requirements (continued)
Please ensure that this manual is read and understood before commencing installation. Failure to comply with the issues
listed below and details printed in this manual can cause product/property damage,severe personal injury,and/orloss of life.
Ensure all requirements below are understood and fulfilled (including detailed information found in manual subsections).
HFiberglass wool and ceramic fiber
materials
The state of California has listed the
airborne fibers of these materials as a
possible cancer hazard through
inhalation. When handling these
materials, special care must be applied.
Suppliers of ceramic fiber products
recommend the following first aid
measures:
-Respiratory tract (nose and throat)
irritation
If respiratory tract irritation develops,
movethepersontoadustfree
location.
-Eye irritation
If eyes become irritated, flush
immediately with large amounts of
lukewarm water for at least 15
minutes. Eyelids should be held away
from the eyeball to ensure thorough
rinsing. Do not rub eyes.
-Skin irritation
If skin becomes irritated, remove
soiled clothing. Do not rub or scratch
exposed skin. Wash area of contact
thoroughly with soap and water.
Using a skin cream or lotion after
washing may be helpful.
-Gastrointestinal irritation
If gastrointestinal tract irritation
develops, move the person to a dust
free environment.
Suppliers of fiberglass wool products
recommend the following precautions
be taken when handling these materials:
Precautionary measures
-Avoid breathing fiberglass dust and
contact with skin and eyes.
- Use NIOSH approved dust/mist
respirator.
- Wear long-sleeved, loose fitting
clothing, gloves and eye protection.
- Wash work clothes separately from
other clothing. Rinse washer
thoroughly.
- Operations such as sawing, blowing,
tearout and spraying may generate
airborne fiber concentration requiring
additional protection.
First aid measures
-If eye contact occurs, flush eyes with
water to remove dust. If symptoms
persist, seek medical attention.
- If skin contact occurs, wash affected
areas gently with soap and warm
water after handling.
HHazardous materials
5285 706 v1.2
Inhalation of fiberglass wool and/or
ceramic fiber materials is a possible
cancer hazard. These materials can
also cause respiratory, skin and eye
irritation.
WARNING Appliance materials of construction,
products of combustion and the fuel
contain alumina, silica, heavy metals,
carbon monoxide, nitrogen oxides,
aldehydes and/or other toxic or
harmful substances which can cause
serious injury or loss of life and which
are known to the State of California
to cause cancer, birth defects and
other reproductive harm. Always use
proper safety clothing, respirators and
equipment when servicing or working
nearby the appliance.

Product Information
Sectional gray cast-iron boiler with triple-pass design.
For operation in closed loop, forced circulation hot water heating systems. This
boiler does not require a flow switch.
The boiler model size selected should be based on an accurate heat loss calculation
of the building. The boiler selected must be compatible with the connected
radiation.
Maximum adjustable high limit setting: 240°F / 110°C
............................................
Maximum allowable working pressure*1: 45psig/3bar........................................
Fuel: #2 fuel oil.............................................................................................................
*1 Cast iron sections are ASME stamped for 58 psig / 4 bar and maximum allowable
temperature of 248°F / 120°C.
Supply/return bypass for large water content systems
For boilers connected to large water content systems (typically systems with
volume > 1 USG / 3.8 ltr for every 13000 Btu/h of boiler input), such as a previous
gravity system with large free-standing radiators, a bypass line from the supply pipe
to the return pipe must be used to avoid flue gas condensation in the heat
exchanger and the vent system. A bypass can be installed on any system as a
preventative measure. Viessmann strongly recommends installing a bypass pipe on
all cast iron boilers.

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 vertical chimney or vent.
Install the boiler on a concrete foundation if:
- the floor may be flooded,
- the floor is not level,
- the boiler will be installed in a residential garage (in this case ensure that the
burner is raised at least 18” / 457 mm above the floor to avoid contact with
flammable vapors and fumes).
Viessmann strongly recommends installing the boiler on a concrete foundation.
Whenever possible install boiler near an outside wall so that it is easy to duct fresh
air directly to the boiler area. In addition, do not use exhaust fans in the boiler room
and do not install the boiler in rooms with refrigeration equipment. This equipment
requires uncontaminated outside air for safe operation - do not install where
chemicals are stored or in a room with negative pressure. See section entitled
“Combustion Air Supply” for further details regarding the above.
Locate boiler on flooring capable of supporting the weight of the boiler filled with
water. Ensure that the boiler location does not interfere with the proper circulation
of combustion and ventilation air within the mechanical room.

Combustion Air Supply
Codes
Provisions for combustion and
ventilation air must be made in
accordance with applicable local codes.
In the absence of local codes, use:
HCSA B-139 for oil installations in
Canada, or
HNFPA 31, Standard for the Installation
of Oil Burning Equipment in the U.S.
Always use latest editions of codes.
General
This equipment requires fresh air for
safe operation and must be installed
ensuring provisions for adequate
combustion and ventilation air exist.
Whenever possible, install boiler near an
outside wall so that it is easy to duct
fresh air directly to the boiler area.
The boiler location must never be under
negative pressure. Exhaust fans, attic
fans, or dryer fans may cause air to be
exhausted at a rate higher than air can
enter the structure for safe combustion.
The heating contractor shall ensure all
of the following requirements are met:
HAn adequate supply of combustion air
must be available to ensure proper
combustion.
HAmbient air temperatures must be
maintained within safe operating
limits.
HWhen a damper is provided in any
opening intended to admit combustion
air into the room within which the
appliance is installed, the damper shall
be interlocked to prevent any burner
from starting before the damper is
fully open.
HEach duct used to convey air from the
outdoors shall have:
1. A cross-sectional area throughout
its length at least equal to the free
area of the inlet and outlet
openings which it connects,
2. A minimum dimension of
3” / 76 mm at any cross-section,
3. When making provision for outside
combustion air, the intake shall not
belessthan1ft/0.3mabovethe
anticipated snow level for the
location.
HThe heating contractor must check
with local authorities (municipal
building department, gas utility) for
combustion air requirements particular
to the area.
5285 706 v1.2
Failure to provide an adequate supply
of fresh combustion air can cause
poisonous flue gases to enter living
space. Flue gases entering living
space can cause carbon monoxide
poisoning which can result in severe
personal injury or loss of life.
WARNING
Nevercovertheboilerorstoredebris
or other materials near the boiler, or
in any way block the flow of
adequate fresh air to the boiler. Never
cover the combustion air opening.
Advise system operator/ultimate
owner accordingly.
WARNING
The boiler must not be located in
areas or rooms where chemicals are
stored, or aggressive vapors (i.e.
bleach, hair spray, methyl chloride,
carbon tetrachloride or
perchloroethylene) or high dust levels
or humidity levels are present. Heat
exchanger corrosion might occur and
reduce the lifetime of the boiler
significantly. If above criteria are not
properly observed and boiler damage
results, any warranty on the complete
boiler and related components will be
null and void.
