Install a single wall, vent connector
from flue outlet to chimney, sloping flue
pipe continuously upward (at least 1/4
inch per foot) toward chimney. The
vent connector should be the same
diameter as the flue collar of the
furnace for the entire length of run and
should not exceed 10 feet in length.
Avoid sharp turns that would create
resistance to the flow of flue gasses.
Vent connector should not extend
beyond the inside wall of the chimney
and must be firmly cemented to
masonry.

IMPORTANT:

For horizontally vented

applications, use the Tjernlund SS1-R
power vent (date code of ??? or later)
installed to the manufacturer’s
installation instructions.

No other appliances or heating
equipment should be connected to the
vent connector servicing the furnace.

Bolt, screw and/or support joints to
avoid sag. Fasten the single-wall vent
connector to the outlet collar of the
furnace with at least two sheet metal
screws. Refer to Figure 1 for distances
to combustible materials.

OIL BURNER / PRIMARY
CONTROL

Oil burner and primary control are
mounted to the furnace as a single
assembly. Standard equipment
consists of the oil burner, ignition
transformer, and flame sensor
(cadmium sulfide cell) with primary
control and low voltage transformer all
included on the burner assembly.

The standard oil burner is equipped
with a single stage fuel pump. This
single stage fuel pump may be used in
either a one or two pipe system. If a
two pipe system is required (burner is
above tank) the lift and length of run
must be considered so as not to
overload the fuel unit.

NOTE:

If the

length of run and the lift is beyond the
recommended limits of the charts
below, a booster prep unit should be
used.

THE USE OF SUCH UNTESTED
AND/OR UNCERTIFIED DEVICES,
ACCESSORIES OR COMPONENTS.

BAROMETRIC DRAFT
CONTROL

The barometric damper (see figure 9) is
a control installed in the flue pipe to
regulate the draft in the furnace. If the
draft increases in the chimney, the
damper opens to maintain the preset
draft in the furnace. Should the draft
decrease in the chimney, the damper
will close to maintain the preset draft of
the oil furnace. A barometric damper is
supplied with each furnace and must be
installed by the following the
instructions supplied by the
manufacturer. The barometric damper
control should be installed between the
flue outlet of the furnace and the
chimney (see figure 10). The
barometric damper control should be
set for proper draft on start up after the
furnace has been operating for 10 to 15
minutes. See Oil Burner Adjustment
Procedure Section for proper draft
settings.

On start up, the furnace must be set
for field conditions with a
combustion kit for proper operation.
NOTE:

Always use a separate

barometric damper for each oil-fired
appliance. Install the barometric
damper with its hinge level and the face
plumb. Tilting causes erratic damper
operation. Installation of a barometric
damper must be in accordance with the
Installation and Operation Instructions
provided with the damper.

The following standards and codes will
help to make the installation. Current
editions of these standards can be
