Replace disposable air filters at least twice a year. Make certain the replacement filter is the same size as the one being replaced. The filter size is marked on the outer edge of the air filter. Install the filter with the arrow marked on the filter pointing toward the furnace. Oil Burner NOTICE: A qualified heating contractor MUST service the oil burner in this furnace at least once a year. Generally, service to the burner will involve a thorough inspection and cleaning of the burner, replacement of the oil nozzle and oil filter, and readjustment of the burner to achieve proper ignition and clean combustion. Blower and Motor NOTICE: The fan motor has sealed bearings that do NOT require lubrication. The blower and fan motor will not normally require any service. This furnace is equipped with a directly-driven blower. Therefore, it will not require any retensioning or replacement of a drive belt. Heat Exchanger c CAUTION: DO NOT attempt to clean the heat exchanger unless electrical power and fuel flow to the furnace are turned off and the furnace is at room temperature. c CAUTION: The combustion chamber refractory material is fragile and can be easily damaged. If the inner radiator of the heat exchanger is cleaned, avoid scraping or hitting the walls of the combustion chamber. CAUTION: Do not brush or scrape the surface of the combustion chamber. It can be easily damaged. NOTICE: A qualified heating contractor MUST inspect the heat exchanger in this furnace at least once a year. If heavy deposits are found, immediate cleaning is required. All heat exchanger surfaces should be as clean as possible for the most efficient operation of the furnace. The heat exchanger may require cleaning after every heating season, as combustion of fuel oil tends to produce soot, particulate matter, and scale, due to corrosion. These materials coat the inner walls of the heat exchanger. This coating reduces the heat transfer effectiveness of the heat exchanger and can hinder the flow of flue gases from the furnace. NOTICE: Accumulation of heavy soot deposits over one heating season may indicate the oil burner is out of adjustment. The heat exchanger may be inspected and cleaned through two (2) access, or cleanout, ports located in the burner compartment, on highboy and lowboy models, or protruding through the front casing panel, on the horizontal/counterflow model. Each cleanout port consists of a 2-inch O.D. tube closed by a pressed-in cap, refer to Figure 9. Figure 9: Location and Design of the Highboy Heat Exchanger Cleanout Ports Using a screwdriver, or a large pair of adjustable jaw pliers, remove each cleanout port cap. With the aid of a portable light source, peer into the heat exchanger. As much as possible, loosen all material and deposits clinging to the heat exchanger walls using wire brushes, or any suitable tool. Collect and remove this material by hand or with the assistance of a vacuum cleaner and a nozzle-type attachment. The heat exchanger may also be cleaned through the flue pipe connection. With the furnace turned off and at room temperature, carefully remove the vent connector and the heat exchanger flue pipe, if equipped, to inspect and clean the heat exchanger. The inner radiator of the heat exchanger may be cleaned from the inside of the combustion chamber. This involves removal of the burner and the burner mounting plate from the heat exchanger. Using a portable light source with a mirror inserted through and into the heat exchanger, check for an accumulation of soot, scale, and particulate matter on the walls and in the base of the drum, or on the floor of the combustion chamber. If a significant accumulation is present, it should be removed. Use a flexible wire brush to loosen the deposits on the heat exchanger walls. Remove any loose foreign material using a vacuum cleaner. Replace all gaskets, if removed, with new (unused) gaskets. Reassemble the burner mounting plate, burner flange, and new gaskets in the reverse order they were removed. A rubber mallet, or equivalent tool, may be useful for reinstalling the caps in the cleanout tubes. Flue and Chimney At least once a year, thoroughly inspect the heat exchanger flue pipe, the vent connector, the chimney, or vent, and the barometric damper for signs of sagging, loose connections, excessive corrosion, and deterioration. Clean, repair, or replace any components for continued safe and proper operation of the furnace. USERS INFORMATION c WARNING: • The area around the furnace should be kept free and clear of flammable vapors, liquids, and material, especially papers and rags. • NEVER burn garbage or refuse in the furnace. NEVER try to ignite oil by tossing burning papers or other material into the furnace. • This oil furnace is designed to burn No. 2 distillate fuel (home heating) oil ONLY. NEVER USE GASOLINE OR A MIXTURE OF OIL AND GASOLINE. • DO NOT attempt to make repairs to the furnace yourself! Operating Instructions For your safety, read this info...
