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.

TANK AND OIL LINES
Oil storage tank should be of an
approved type installed in accordance
with the National Board of Fire
Underwriters and local regulations.
In accordance with standards of the
National Board of Fire Underwriters,
inside tanks should be at least seven
feet from burner, convenient for
installing the fill, vent and feed lines.
The fill and vent lines should be run to
a convenient outdoor location and
should slope downward to tank. They
should terminate in approved fittings.
An approved type of oil gauge should
be installed in accordance with
manufacturer's instructions. Copper
tubing no smaller than 3/8" O.D. is
recommended for suction or feed line
on basement tank installations. A hand
shut-off valve should be installed at the
tank outlet. An oil filter should be
installed in the suction or feed line.
Underground tanks or tanks below the
burner may require a two-pipe hook-
up. A check valve should be installed
in the suction line to keep the line
primed and the internal by-pass in the
fuel unit must be plugged as per
instructions furnished with the burner.
All oil lines must be tight and free of
traps. Lines should be buried or
otherwise protected from mechanical
injury. (See Typical Installation
Diagrams.)

WARNING
!
TURN OFF ELECTRIC POWER AT
FUSE BOX OR SERVICE PANEL
BEFORE MAKING ANY ELECTRICAL
CONNECTIONS. FAILURE TO DO SO
CAN CAUSE ELECTRICAL SHOCK
RESULTING IN PERSONAL INJURY
OR DEATH.

CABINET MUST BE PERMANENTLY
GROUNDED. A GROUND SCREW IS
PROVIDED IN THE JUNCTION BOX
FOR THIS PURPOSE.
GROUND CONNECTION MUST BE
COMPLETED BEFORE MAKING ANY
LINE VOLTAGE CONNECTIONS.
WARNING
!
FAILURE TO GROUND APPLIANCE
COULD RESULT IN ELECTRICAL
SHOCK, FIRE, PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.
Installation of the electric supply line
should be in accordance with the
National Electric Code ANSI/NFPA No.
70, latest edition, and local building
codes.
Use a separate fused branch electrical
circuit containing a properly sized fuse
or circuit breaker. Run this circuit
directly from the main switch box to an
electrical disconnect (switch) which
must be readily accessible and located
within sight of the furnace.

LENGTH OF RUN - FEET
The total wire length is the distance from the furnace to the thermostat and back
to the furnace.
NOTE: Do not use 24 volt control wiring smaller than No. 18.
Connect from the disconnect to the
junction box on the furnace inside the
control compartment. Discard test
leads and connect the line voltage
wires in their place. (See appropriate
wiring diagrams.)
NOTE: H (hot) and N (neutral) polarity
must be observed when making field
connections to the furnace. The limit
control will not interrupt H (hot) circuit
if leads are reversed.
THERMOSTAT
Install the room thermostat in
accordance with the instruction sheet
packed in the box with the thermostat.
Run the thermostat lead wires inside
the blower compartment and connect
to low voltage terminals as shown on
the wiring diagram. Never install the
thermostat on an outside wall or where
it will be influenced by drafts,
concealed hot or cold water pipes or
ducts, lighting fixtures, radiation from
fireplace, sun rays, lamps, televsions,
radios or air streams from registers.
Refer to instructions packed with the
thermostat for "heater" selection or
adjustment.
NOTE: Do not use 24 volt control
wiring smaller than No. 18 AWG.
HEAT ANTICIPATOR
SETTING
The heating thermostat anticipator
should be set for a 0.10 amp draw.
