2 on Page 4). Information Contained in Chapter I Following is an excerpt from a typical listing in the chapter along with an explanation of the information that is presented. Models with higher Annual Fuel Utilization Efficiency (AFUE) ratings use less fuel. To calculate how much less fuel, a procedure is provided in the next part of this introduction that will allow comparison of models of different AFUE ratings.

1 and
3 of Chapter
1 will be listed for natural gas, propane gas, or both. In Sections
2 and 4, this designation will be omitted since the models in these sections are listed for oil. 2. Name of Company: This may also be accompanied by a trade name or mark. 3. Model Number: Lists the model number of the units in the program. Certain furnaces listed in this chapter have the same ratings for efficiency related parameters such as input, capacity, and AFUE even though they have different model numbers. These units may be listed on the same line with interchangeable portions of the model numbers listed with an asterisk. For example, if the two models GF100-1 and GF100-2 have the same efficiency ratings they could be listed as GF100-*. 4. Configuration: Configuration of the model and installation location used for ratings. Configurations and installation locations are further described at the beginning of each section. 5. Footnote: This column is for referencing footnotes. 6. Input, Mbtuh: This figure represent the amount of fuel that the model consumes in one hour. It is defined as the rate of energy supplied in a fuel to a furnace or boiler when operating under continuous burning (steady-state) conditions: a) Mbtuh stands for thousands of British Thermal Units (Btu'
s) used in one hour and is a term used to measure energy;
for example, a few hundred Btu'
s provide enough energy to make a pot of coffee. Some larger homes may require as much as 8........
