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 13 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.
IMPORTANT
This boiler is equipped with an outdoor reset module that saves energy by reducing
the boiler water temperature as the heating load decreases. This feature is equipped
with an override which is provided primarily to permit the use of an external energy
management system that serves the same function.
THIS OVERRIDE MUST NOT BE USED UNLESS AT LEAST ONE OF THE
FOLLO ING CONDITIONS IS TRUE:
- an external energy management system is installed that reduces the boiler water
temperature as the heating load decreases.
- This boiler is not used for any space heating.
- This boiler is part of a modular or multiple boiler system having a total input of
300,000 BTU/hr or greater.
- This boiler is equipped with a tankless coil.

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 should 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.
5671 44 v1.

Fresh Air
11
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
be less than 1 ft / .3 m above the
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.
5671 44 v1.
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.
ARNING
Never cover the boiler or store debris
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.
ARNING
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.

Unconfined spaces
Where the boiler is located in an
unconfined space in a building having
insufficient infiltration, additional air for
combustion and ventilation shall be
obtained from outdoors or from spaces
freely communicating with the
outdoors. Under these conditions,
permanent opening(s) shall be provided
so that the total air received through
these openings will be at least as much
as would be admitted by openings
having a total free area of 1 in

If the boiler is located in a confined
space and that obtains all of its air for
combustion and ventilation from
outside, the building shall be provided
with two permanent openings, one near
the top of the enclosure and another
near the bottom. Each opening shall
communicate directly or by means of
ducts with the outdoors or to such
spaces (such as a crawl space) that
freely communicate with the outdoors,

The vent system must comply with all
applicable local and/or national codes.
If installing boiler with a side wall vent
system, ensure all manufacturer’s
requirements are met.
Venting codes
For oil-fired boilers install venting
system in accordance with all applicable
local codes:. In the absence of local
codes, follow national codes
HLocal codes or CSA B139- in
Canada, or
HNFPA-31 in the U.S.
Building codes
Masonry or concrete or metal chimneys
(smokestacks) shall be constructed
according to the requirements of the
province/state building code or, in the
absence of such regulations, in
accordance with:
HCSA Standard CAN/CSA-A4 5
(National Building Code of Canada) in
Canada, or
HNFPA 211 (Standard for Chimneys,
Fireplaces, Vents, and Solid
Fuel-Burning Appliances) in the US.
Metal chimneys also shall meet the
requirements of Chapter 4 of
NFPA 211.
In Canada, factory built chimneys shall:
HConform to ULC Standards
CAN/ULC-S629 for 12 2°F / 65 °C,
CAN/ULC-S6 4 for Type A, or
CAN/ULC-S6 9 for Type L chimneys,
HBe certified and installed in
accordance with the manufacturer’s
certified instructions, and
HBe provided with a clean-out opening
that is equipped with a tight-fitting
removable cap, and constructed so
that no air can enter the clean-out
facility when the cap is in place.
In the U.S., factory built chimneys shall:
HMeet the requirements of NFPA, and
HBe listed, installed and used in
accordance with their listings and
manufacturer’s instructions.
General
The heating contractor shall ensure all
of the following requirements are met:
HThe vent system shall ensure that no
hazard is created by the products of
combustion.
HProvision shall be made to vent the
products of combustion safely to
outside the building, and such venting
shall not pass through or be installed
in return air, supply air, ventilating, or
combustion air ducts or shafts.
HSufficient air for combustion of the oil
and ventilation of the appliance shall
be supplied to the space wherein the
appliance is located (see section
entitled Combustion Air Supply).
HThe house and its mechanical
systems shall be inspected to
determine if operation of exhaust
devices could lead to levels of
depressurization of the house that
would adversely affect the operation
of the oil-burning appliance and its
venting system. If such is the case,
the building owner shall be informed
of the situation in writing.
HThe chimney shall be inspected to
ensure that the material construction,
condition, and size are suitable for the
application.
HThis boiler/burner combination shall
not be connected to an unlined
chimney. Such chimneys shall be lined
in accordance with the applicable
codes and standards.
HThe chimney shall be capable of
exhausting the products of
combustion and of producing a draft
not less than that recommended by
the manufacturer of the appliance
connected thereto, during the mildest
weather conditions under which the
appliance is expected to operate.
During cold weather testing, excess
flow performance shall be
demonstrated to ensure that flow is
adequate in warmer weather.
HAn oil burning appliance that depends
on natural chimney draft shall be
connected to an individual chimney
vent used for no other appliance,
except as permitted by the applicable
codes and standards.
HThe vent connector of this boiler must
not be connected into any portion of
mechanical draft systems operating
under positive pressure.
HA chimney flue shall extend at least 3
ft / 1 m above the highest point at
which the chimney comes in contact
with the roof, and not less than 2 ft /
.6 m above the highest roof surface
or structure within 1 ft. / 3 m of the
chimney on a horizontal plane
perpendicular to the chimney. Not
more than 8” / 2 mm of chimney
flue above the top of the chimney cap
shall be considered in computing
height.
HDown draft and condensation
problems must be corrected.
5671 44 v1.
Improper sizing, maintenance,
termination of vent or chimney can
cause flue gases to enter living
space. Any blockage of vent or
chimney by birds’ nests, ice, snow,
debris, or other materials can cause
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.
ARNING
Never operate the boiler/burner
without an installed venting system
which safely vents all products of
combustion to the outdoors. The vent
system must comply with all
applicable local and/or national codes.
