This article lists significant oil-fired heating furnace (warm air system) defects, definitions, and home inspection education topics. This article series, beginning at BUILDING DEFECTS LISTS, provides lists of common building defects and basic defect knowledge that also outline recommended curriculum content for home inspector education. The building defects and inspection points listed in these articles also guide homeowners and home buyers to building areas that merit careful attention and often point areas of safety concern or important maintenance and repair tasks. Readers should see HEATING SYSTEMS for our complete list of articles on this topic. Also see HOME & BUILDING INSPECTORS & INSPECTION METHODS. Use the Search Box at the top or bottom of these pages to find in-depth information about building, energy savings, and indoor environment inspection, diagnosis and repair at this website. Watch out: these inspection lists do not list all possible defects for the systems discussed, and not all home or building inspectors will examine all of the items listed here. CONTACT us to suggest corrections or additions to articles at this website. Also see FURNACES, HEATING and DUCT SYSTEM & DUCT DEFECTS. These curriculae and building defect lists are based on smilar curriculum documents first prepared by Joe Scaduto, an ASHI member who prepared course material for Northeastern University's Building Inspection Certificate program in 1988, subsequently by DF, InspectApedia's editor, for New York University ca 1988 and later, with others, recommended to ASHI, the American Society of Home Inspectors. ASHI did not adopt this material though currently that association as well as others offer extensive HOME INSPECTOR EDUCATION material. The curriculum and lists of defects are informed by additional analysis of the process of home inspection that was developed beginning Calgary, AB for Canadian and U.S. home inspector education and certification examinations in 1997. Other early contributors to home inspection education in the U.S. and Canada include Dr. Jess Aronstein, Alan Carson, Mike Casey, Mark Cramer, John Cox, Dwight Barnett, Douglas Hansen, Rick Heyl, Larry Hoytt, Bill Merrill, Kevin O'Malley, Dennis Robitalille, Keith Peddie, Pat Porzio, Roger Robinson. © Copyright 2012 InspectAPedia.com, All Rights Reserved.

Home Inspection Education Curriculum - Heating: Oil Fired Furnaces4.2 Oil Fired Warm Air Furnaces Inspection Recommendations & Typical Defects List4.2.1 Knowledge Base for Oil Fired Warm Air Furnaces Inspection1. List the materials, function and location of the components of a typical oil fired forced air furnace including ? the fuel storage and supply system, burner, heat exchanger, draft regulator(barometric damper), vent connector, combustion air supply, cabinet, controls, ducts, registers, and grills. 2. Describe the features of adequate installation and repair technique for oil fired furnaces. 3. Define the following terms: oil safety valve, fire safety valve, atomizing oil burner (gun type burner), electrode, flame retention head, refractory (fire pot), blast tube (draft tube), transformer, fuel pump, ignition transformer, primary control (primary controller, stack relay, primary relay), flame sensor (Fire-eye, photo cell, cad cell), barometric damper (draft regulator), vent connector, side wall venting, automatic vent damper. 4. Describe the normal operating cycle of an oil fired forced air furnace from call for heat to shut down. 5. Outline the typical life expectancies of oil fired warm air furnaces. 6. Identify the codes or standards which apply to oil fired appliances and warm air furnaces in your area. 4.2.2 Inspection Skills Oil Fired Warm Air Furnaces Inspection1. Describe the inspection procedure for oil fired warm air furnaces. 2. Identify the following common defects listed on the next page. 3. Describe the implication of each defect. 4. Identify the safety issues for the inspector and occupant of the home(fire, oil spill, combustion product, pollution, injury due to moving parts). 5. Communicate findings to client verbally and in writing, recommending corrective action where needed.
