Failure to properly vent this furnace can
result in property damage, personal injury
and/or death.
Side-wall Vented:
Using the Beckett AFII or Riello 40-BF burner with the
integral pre and post purge controls, the system can be
side-wall vented with the new DV-2000™ venting
system for maximum efficiency, and without the use of a
side-wall power ventor. The unit will be operated at a
positive
overfire draft and stack draft.
WARNING
WARNING
Poison carbon monoxide gas hazard
Never co-vent the furnace with another
combustion appliance when
side-wall
venting.
To do so may result in asphyxiation and
death to the occupants
4.2)
Chimney installations:
The oil furnaces, when set up for chimney venting, are
certified for use with L-vent, A-vent, tile-lined and metal-
liner-tile-lined chimneys, and can be vented both with
and without a barometric draft damper. However, the
furnace has not been certified without the barometric
damper when it is to be co-vented with another oil-fired
appliance, such as a water heater.
When a damper is used, the basement air entering the
damper reduces the possibility of vent condensation.
However, if the barometric damper is not used, a
chimney liner with insulation must be employed.
With a barometric damper:
The appliance may be installed in a chimney of the
proper size and adequate chimney base temperature as
specified in the Installation Code. The relevant excerpt
from the code is found in this section - Use it as a guide
when local or national codes do not exist.
Without a barometric damper:
Due to the lack of dilution air that would ordinarily be
drawn into the barometric damper, the dew point of the
flue gasses is raised. To offset the increased tendency
for vent condensation, the chimney must be lined.
Additionally, the liner must be insulated according to the
insulating procedure recommended by the
manufacturer of the liner.
WARNING
WARNING
Poison carbon monoxide gas hazard
Never install a hand operated damper in
the vent pipe. However, any Underwriters
Laboratories listed electrically operated
automatic type vent damper may be
installed if desired. Be sure to follow
instructions provided with vent damper.
Read and follow all instructions in this
section.
Failure to properly vent this furnace or
other appliances can result in property
damage, personal injury and/or death.
Vent connectors:
For installations without barometric damper, the vent
connector should be as short as possible and either be
of double wall construction, or be of single wall
construction insulated with 1” of insulation. It should
rise a minimum of 1/4” per foot from the furnace to the
chimney. Field fabricated connectors should be a
minimum of 28 gauge. The joints must be mechanically
secure and there must be no flue product leakage at the
joints.
CAUTION
When the furnace (chimney installation) is co-
vented with other combustion appliances such
as a water heater, the allowable venting
materials (i.e. L-Vent etc.) for use with those
appliances should also be investigated.
Flue pipe sizing:
The following table is an except from the installation
code and indicates permitted flue sizes and minimum
base temperatures for circular flues in chimney with
thermal resistance less than R6 (6 ft
2
•
hr
•°
F / Btu).
Where a new appliance, burner, or chimney is installed,
chimney vent sizes and maximum flue-gas
temperatures (measured at the chimney connector with
the barometric damper shut, after 5 minutes of
operation) shall comply with the table #2.
