Vitorond 100, VR1 40 to 63, 161 to 245 Installation and Service
Venting Connection
General
The heating contractor shall ensure all of the following
requirements are met:
The vent system shall ensure that no hazard is created
g
by the products of combustion.
Provision shall be made to vent the products of
g
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.
Sufficient air for combustion of the oil and ventilation
g
of the appliance shall be supplied to the space wherein
the appliance is located (see section entitled
Combustion Air Supply).
The house and its mechanical systems shall be
g
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.
The chimney shall be inspected to ensure that the
g
material construction, condition, and size are suitable
for the application.
This boiler/burner combination shall not be connected
g
to an unlined chimney. Such chimneys shall be lined
in accordance with the applicable codes and standards.
(continued)
The chimney shall be capable of exhausting the
g
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.
An oil burning appliance that depends on natural
g
chimney draft shall be connected to an individual
chimney vent used for no other appliance, except
as permitted by the applicable codes and standards.
The vent connector of this boiler must not be
g
connected into any portion of mechanical draft
systems operating under positive pressure.
A chimney flue shall extend at least 3 ft (1 m) above
g
the highest point at which the chimney comes in
contact with the roof, and not less than 2 ft (0.6 m)
above the highest roof surface or structure within
10 ft. (3 m) of the chimney on a horizontal plane
perpendicular to the chimney. Not more than 8"
(200 mm) of chimney flue above the top of the
chimney cap shall be considered in computing height.
Down draft and condensation problems must be
g
corrected.
WARNING
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.
WARNING
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.
