4The 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, andmore reliable service from your new appliance.COMBUSTION AIR REQUIREMENTSCombustion air requirements become more importantfor your new furnace. More efficient units have lowerflue temperatures and less natural draft. Especiallywith new homes and with older homes that have beenweatherized (storm windows, vinyl siding, additionalinsulation, etc.) infiltration air may no longer beenough to supply the necessary combustion air to yourfurnace. In these cases outside air will need to be in-troduced into the furnace location or directly into thefurnace vestibule. This can be accomplished by meansof louvered openings, ductwork, or tubing. Your dealeror service technician has access to the necessary airrequirements specified by the National Fire ProtectionAgency.Some symptoms of a lack of the proper amount ofcombustion air are:1. Excessive oil burner after drip and oil fumes.2. Sooting.3. Melted oil burner couplings and/or ignitor/relaycontrol.4. A condition where air band or air shutter settingsmust be more open than normal to achieve propercombustion.5. Lockouts on start-up.HERE ARE A FEW DO’S ANDDO NOT’S• DO become familiar with the instructions.• DO use filters. Check them periodically and make surethat they are clean.• DO check to see that your home has adequate insula-tion, weatherstripping, caulking, and storm windows.Eliminating infiltration of outside air and drafts can saveup to 40% of your fuel bill.• DO NOT waste fuel by setting your thermostat toohigh. Energy conservation experts recommend daytimethermostat setting of 68° F, with a lower setting at night.• DO NOT turn off the furnace when you expect to beaway for more than a day. Instead, lower the thermostatsetting by a few degrees. You can then restore normalcomfort 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 HOW YOURHEATING SYSTEM WORKSThe furnace operates automatically. It is controlled by athermostat 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 thetransformer energizes the fan control board. The fancontrol energizes the ignition control. The ignition con-trol automatically lights the burner.The electronic fan control automatically turns on theblower after 30 sec. Fan on control is not adjustable. Theair moved over the heat exchanger by the blower iswarmed 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. Theblower continues to run until the selectable fan off timeperiod has expired.WARNINGThe unit cabinet must have an uninterruptedor unbroken electrical ground to minimizepersonal injury if an electrical fault shouldoccur. This may consist of electrical wire orapproved conduit when installed in accor-dance with existing electrical codes. Do notuse oil piping as an electrical ground. Fail-ure to follow this warning could result in anelectrical shock, fire, or bodily harm.WARNINGReturn air must not be taken from the roomin which the appliance is installed. All ductconnections to the furnace must be airtightto avoid a “negative” pressure conditionwithin the room. Incorrect ductwork termi-nation and sealing will create a hazardouscondition which could lead to bodily harm.CAUTIONThe ability to properly perform maintenanceon this equipment requires certain mechan-ical skills and tools. If you are at all uncer-tain, contact your dealer for qualifiedmaintenance and service.!!!
