WELCOMETO A NEW GENERATION
OF COMFORT
Congratulations on the purchase of your new 80+%
efficient oil furnace. If you are replacing an older, less
efficient oil furnace, you may use 20% to 30% less oil.
In order to achieve greater efficiency, your new fur-
nace operates differently in some respects than your
old furnace.
One main difference between an older and newer oil
furnace is in the operation of the oil burner. The new
style retention head oil burner operates at twice the
RPM, therefore the sound is different — not louder but
probably a different pitch. This higher RPM delivers
more air which burns the oil more efficiently.
You will also find the main blower comes on sooner
than before. This is done with efficiency in mind but
alsotokeepheatexchanger temperatures within allow-
able limits. The more efficient furnace design heats up
faster requiring a shorter blower on time.
Your new oil furnace blower is also sized for air con-
ditioning and will deliver (even on heating speeds)
more air than your old furnace. Depending on your ex-
isting ductwork this could lead to a noticeable differ-
ence in air noise. A change in ductwork could be
required to reduce air noise, especially if air condition-
ing is being added.
Please read the remainder of this manual in order to
familiarizeyourselfwiththeoperation of your furnace.
IMPORTANT FACTS
FOR PROPER AND SAFE
OPERATION OFYOUR FURNACE:
• DO NOT place combustible materials, gasoline, and/
or other flammable vapors or liquids on, against, or
near the furnace or flue pipe.
•
DO NOT block or obstruct air openings on the fur-
nace, air openings communicating with the area in
which the furnace is installed, and the spacing around
the furnace. These provide air for combustion and
ventilation.
•
DO NOT store anything near or in contact with the
furnace such as: spray or aerosol cans, rags, brooms,
dust mops, vacuum cleaners or other cleaning tools,
soap powders, bleaches, waxes or other cleaning com-
pounds, plastic or plastic containers, gasoline, kero-
sene, cigarette lighter fluid, dry cleaning fluids, or
painting compounds.
FORYOUR SAFETY
Do not store or use gasoline or other flam-
mable vapors and liquids in the vicinity of
this or any other appliance.
WARNING
Improper installation, adjustment, alter-
ation, service, or maintenance can cause in-
jury or property damage. Refer to this
manual. For assistance or additional infor-
mation consult a qualified installer, service
agency, or the oil supplier.
!
WARNING
Turn off the oil supply and electrical power
to furnace before performing any mainte-
nance or service on unit. Failure to take this
precaution may result in personal injury
due to electrical shock or uncontrolled oil
leakage.
CAUTION
A furnace that is installed in an insulated
space must be kept free and clear of insulat-
ing materials. After the furnace is installed,
or whenever additional insulation is added,
check that all combustion air intakes are
free and clear and that all clearance dimen-
sions are maintained. INSULATING MATE-
RIALS MAY BE COMBUSTIBLE.
WARNING
Do not use this furnace if any part has been
under water. Immediately call a qualified
service technician to inspect the furnace
and to replace any part of the control system
and any oil control which has been under
water. Failure to comply with this warning
could lead to equipment failure, electrical
shock, and a hazardous condition which
may lead to bodily harm.

The operation and care of your unit is simple and easy.
By following these operating and maintenance proce-
dures, you can expect to receive better, longer, and
more reliable service from your new appliance.
COMBUSTION AIR REQUIREMENTS
Combustion air requirements become more important
for your new furnace. More efficient units have lower
flue temperatures and less natural draft. Especially
with new homes and with older homes that have been
weatherized (storm windows, vinyl siding, additional
insulation, etc.) infiltration air may no longer be
enough to supply the necessary combustion air to your
furnace. In these cases outside air will need to be in-
troduced into the furnace location or directly into the
furnace vestibule. This can be accomplished by means
of louvered openings, ductwork, or tubing.Your dealer
or service technician has access to the necessary air
requirements specified by the National Fire Protection
Agency.
Some symptoms of a lack of the proper amount of
combustion air are:
1. Excessive oil burner after drip and oil fumes.
2. Sooting.
3. Melted oil burner couplings and/or ignitor/relay
control.
4. A condition where air band or air shutter settings
must be more open than normal to achieve proper
combustion.
5. Lockouts on start-up.
HERE ARE A FEW DO’S AND
DO NOT’S
• DO become familiar with the instructions.
•
DO usefilters.Check them periodically and makesure
that they are clean.
•
DO check to see that your home has adequate insula-
tion, weatherstripping, caulking, and storm windows.
Eliminatinginfiltrationof outside air and drafts can save
up to 40% of your fuel bill.
•
DO NOT waste fuel by setting your thermostat too
high. Energy conservation experts recommend daytime
thermostat setting of 68
° F, with a lower setting at night.
•
DO NOT turn off the furnace when you expect to be
away for more than a day. Instead, lower the thermostat
setting by a few degrees. You can then restore normal
comfort level quickly and save fuel too.
•
DO NOT block registers with furniture.
•
DO NOT put a lamp, TV, or radio near your thermo-
stat. This will cause it to give a false reading.
HERE’S HOWYOUR
HEATING SYSTEMWORKS
The furnace operates automatically. It is controlled by a
thermostat which you set at the temperature most com-
fortable to you. When the inside temperature drops be-
low this setting, your thermostat starts the furnace.
When the thermostat calls for heat, power from the
transformer energizes the fan control board. The fan
control energizes the ignition control.The ignition con-
trol automatically lights the burner.
The electronic fan control automatically turns on the
blower after 30 sec. Fan on control is not adjustable.The
air moved over the heat exchanger by the blower is
warmed and passes through the ducts to the room regis-
ters.
When the thermostat is satisfied, the circuit is de-ener-
gized and the primary control shuts off the burner. The
blower continues to run until the selectable fan off time
period has expired.
WARNING
The unit cabinet must have an uninterrupted
or unbroken electrical ground to minimize
personal injury if an electrical fault should
occur. This may consist of electrical wire or
approved conduit when installed in accor-
dance with existing electrical codes. Do not
use oil piping as an electrical ground. Fail-
ure to follow this warning could result in an
electrical shock, fire, or bodily harm.
WARNING
Return air must not be taken from the room
in which the appliance is installed. All duct
connections to the furnace must be airtight
to avoid a “negative” pressure condition
within the room. Incorrect ductwork termi-
nation and sealing will create a hazardous
condition which could lead to bodily harm.
CAUTION
The ability to properly perform maintenance
on this equipment requires certain mechan-
ical skills and tools. If you are at all uncer-
tain, contact your dealer for qualified
maintenance and service.

The heat sensing switch performs as the furnace high
temperature limit switch. If the furnace overheats for
any reason, the limit switch opens, breaking the circuit
to the burner. The blower motor will be energized and
as the unit cools the limit switch will close.This relights
the burner, however, unless the overheating condition is
corrected, the furnace will continue to cycle on limit.
This unit is equipped with an interrupted ignition elec-
tronic control. If the main burner does not ignite within
30 sec from the call for heat, the control will lock out.
The red button on top of the control must be depressed
for 3 sec in order to reset the control.The control CAN-
NOT be reset from the room thermostat.

MAINTAININGYOUR UNIT
In order to keep your furnace running properly and at
the efficiency for which it was designed, the furnace
MUST be inspected and serviced once a year. Lack of
yearly service could lead to poor furnace performance
and damage to the furnace.
Here are the things you should do and have your service
technician do for you.
Homeowner:
1. Inspect and clean filter.
2. Make sure the following areas are clear:
A.Outlet and return registers.
B. Air openings to furnace and furnace area.
C. Chimney or flue exhaust.
3. Set up yearly service.
Technician:
Minimum yearly service should include the following:
1. Check flue and secondary tube passage ways includ-
ing chimney — clean if necessary.
2. Change oil filter.
3. Change nozzle.
4. Check and adjust combustion and draft.

NOTE : Before you start, TURN OFF all electrical
power to unit and turn thermostat to OFF.
Filters
Afilterissuppliedwiththe furnace. It is NECESSARY
THAT ALL FURNACES BE EQUIPPED WITH A
FILTER.
If a different type of filter is used, it must be an equiva-
lent high airflow capacity.
Keeping Filters Clean
As a homeowner, this is your most important responsi-
bility. A dirty filter reduces the efficiency of your sys-
tem, causes erratic performance of controls, and could
result in damage to the motor or heat exchanger.
1. Inspectfiltersatregularintervalsdepending upondirt
conditions. For new homes, check filters every week
for 4 consecutive weeks. In all cases, inspect your
filters at least every 3 to 4 weeks when the system is
in constant operation. Replace or clean filter at least
at the beginning of each season (heating & cooling)
and thereafter as needed.
2. If the permanent filter supplied with the unit be-
comes dirty, it can be cleaned with cold water and
soap.
Be sure that the filter is thoroughly dry before installing
back into the furnace.
Lubricating Motors
Direct drive motor and blower assemblies are factory
lubricated and normally do not require oiling. If oiling
is required, lubrication of the blower motor is to be per-
formed only by a qualified service technician.
Here is A Handy Checklist
If your furnace fails to operate properly, first check the
following. It may save you the cost of a service call:
1. Is your room thermostat set correctly? On heating/
cooling systems, the thermostat should be set to
HEAT or COOL mode and the fan set to AUTO or
ON (continuous fan operation).
2. Are the electrical power and oil supplies both on?
3. Are the filters clean?
4. Is the ignition control on the burner operational
(not in lockout)? The red button on top of the
control must be depressed for 3 sec in order to reset
the control.
If the answer to these questions isYES and the furnace
still does not operate properly, call your authorized
dealer for service.
WARNING
Never operate unit without a filter or with fil-
ter access door removed. Failure to adhere
to this warning could lead to a hazardous
condition which could lead to equipment
damage and bodily harm.
