WELCOME TO 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
also to keep heat exchanger 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
familiarize yourself with the operation of your furnace.
IMPORTANT FACTS
FOR PROPER AND SAFE
OPERATION OF YOUR 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.
FOR YOUR 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.
