Congratulations...

...you have one of the most modern oil furnaces made. Your unit
has been carefully selected to keep you warm and comfortable
during the winter months. It will deliver superb performance with
only minimal help from you.

To keep your operating costs low and to eliminate unnecessary
service calls, we have provided a few guidelines to help you
with your furnace. These guidelines will help you understand
how your furnace operates and how to maintain it so you can

get years of safe and dependable service.

For your safety – read before operating

This appliance is equipped with an ignition device which
automatically lights the burner. Do not try to light the burner
by hand.

Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and oil
control which has been under water.

Periodic Inspections

Your oil furnace is designed to give many years of efficient,
satisfactory service. However, the varied air pollutants com-
monly found in most areas can affect longevity and safety.
Chemicals contained in everyday household items such as
laundry detergents, cleaning sprays, hair sprays, deodorizers,
and other products which produce airborne residuals may have
an adverse affect upon the metals used to construct your
furnace.

It is important that you visually inspect the conditions of the
burner and vent from the furnace. A flashlight will be useful for
these inspections. Make one inspection prior to the beginning of
the heating season and another during the middle. Should you
observe unusual amounts of rust, flakes or other deposits,
coatings, or corrosion, it is important that you call your autho-
rized dealer at once to obtain a qualified service inspection.
Even if no unusual rust or other deposits are observed, it is
recommended that the furnace be inspected and serviced
at least once per year by a qualified service technician.

Installation and service must be performed by a quali-
fied installer or service agency.
