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.
