FOREWORD

In 2007, the members of the Gas Appliance Manufacturers Association (GAMA) and the Air-Conditioning and Refrigeration Institute (ARI) merged to become the Air-Conditioning, Heating, and Refrigeration Institute (AHRI). AHRI is one of the largest associations in the nation, representing 350+ member companies accounting for more than 90% of the residential and commercial air-conditioning, space heating, water heating, and commercial refrigeration equipment manufactured and sold in North America. Regulators increasingly depend on AHRI for accurate and unbiased evaluation of HVACR equipment. Our certification programs demonstrate to government, building owners and homeowners that equipment performance claims have been independently measured and verified in accordance with federally mandated test procedures, instilling consumer confidence and enabling fair product comparisons. There are a number of product sections within AHRI. Four of those have developed separate efficiency certification programs continuing to operate under the GAMA Efficiency Rating Certified label: the Furnace, Hydronics Institute, Direct Heating and Water Heater Sections. The GAMA Furnace and Hydronics Institute Divisions sponsor the certification program for residential gas and oil central furnaces and boilers. The GAMA Direct Heating Division sponsors the efficiency certification program for vented gas room heaters, floor furnaces and wall furnaces. The GAMA Water Heater Division sponsors the efficiency certification program for residential and commercial gas, oil, electric (including heat pump type) water heaters. This Directory lists the models for all participating manufacturers in each of the programs. The following is the format for those listings:

CHAPTER I Gas and Oil Central Heating Equipment

CHAPTER II Gas Vented Direct Heating Equipment

CHAPTER III Gas, Oil, Electric, Combination, & Instantaneous Water Heaters CHAPTER IV Commercial Gas, Oil, Electric, & Instantaneous Water Heaters CHAPTER V Commercial Gas and Oil Central Heating Equipment

Each participant in the GAMA Efficiency Certification Program is entitled to display the GAMA Certification Symbol (Seal), Figure 1, on units of models covered by the program. The seal may be affixed to the unit only at the time and place of manufacture. The seal may also be displayed on specification sheets, advertising and on other literature that either specifies ratings or claims participation in the program. The seal and listing in this Directory are an indication that the equipment's efficiency rating as well as output heating capacity for heating equipment and first hour rating for water heating equipment have been determined and are accurately stated in accordance with the applicable efficiency test method; no other warranty, representation, endorsement or other statement, expressed or implied, is made.

INTRODUCTION Description of GAMA Furnace and Boiler Efficiency Certification Program Chapter I is a product of the residential Furnace and Boiler Efficiency Certification Program sponsored by AHRI in cooperation with its industry members. The program uses an independent laboratory to verify the furnace and boiler manufacturers' stated Annual Fuel Utilization Efficiency (AFUE) and output heating capacity as determined by testing in accordance with the Department of Energy's Uniform Test Method of Measuring the Energy Consumption of Furnaces and Boilers. Gas and oil furnaces with input ratings less than 225,000 Btu/hour, gas and oil boilers with input ratings less than 300,000 Btu/hour, are currently included in the program. Administration of the program includes the quarterly publication of this electronic "Consumers' Directory of Certified Efficiency Ratings", which identifies certified products enrolled in the certification program and lists the input rating, certified heating capacity and Annual Fuel Utilization Efficiency (AFUE) for each. Central Heating Equipment Defined Central Heating equipment listed in this chapter is gas or oil burning furnaces or boilers. Furnaces supply heat to space remote from the furnace location through a system of ducts with air as the heating medium. Boilers supply heat to space remote from the boiler location through a piping and radiator system with hot water or low-pressure steam as the heating medium. Chapter I Format This chapter is divided into four (4) separate sections described as follows:

Section 1 - Residential Gas Central Furnaces

Section 2 - Residential Oil Central Furnaces

Section 3 - Residential Gas Boilers

Section 4 - Residential Oil Boilers

SEPTEMBER 30, 2008 PAGE 3

USE OF CHAPTER I Each section provides a listing of the models of each of the companies participating in this program along with information on the configuration of the model, its size, heating capacity and efficiency rating (AFUE). Participating companies are listed in the Directory alphabetically. In order for a potential purchaser of central heating equipment to get the optimum use from this chapter, there are two requirements:

1) an understanding of the information and terminology that it contains, and 2) (for purposes of selecting heating equipment) the information in the chapter must be supplemented with information concerning

the type of installation and heat loss of the home to be heated. (See Step 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. SAMPLE LISTING

1. Type of Fuel: Sections 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 80,000-90,000 Btu’s an hour for heating on very cold days.

b) “Steady-State Conditions” are conditions of continuous burner operation during which fuel consumption of the furnace or boiler is measured, somewhat like measuring your car’s gasoline mileage under steady highway driving conditions.

7. Heating Capacity, Mbtuh: This figure tells how much heat the model can produce in one hour operating under steady-state

conditions expressed in thousands of Btu’s per hour. For isolated combustion or outdoor units the Heating Capacity is determined by multiplying the specified input by the steady-state efficiency, as tested, and subtracting an additional term to account for jacket losses which would go into an unheated environment.

SEPTEMBER 30, 2008 PAGE 4

8. PE, Watts: The electrical energy input rate supplied to the power burner (combustion air blower, fuel pump, damper motor) of a furnace or boiler operating under continuous burning (steady-state) conditions.

9. Eae, kWh/yr: The average annual auxiliary electrical energy consumption for a gas furnace or boiler in kilowatt-hours per year.

It is a measure of the total electrical energy supplied to a furnace or boiler during a one-year period. 10. Ef, MMBtu/yr: The average annual fuel energy consumption for a gas furnace or boiler, in millions of Btu's per year. 11. AFUE, %: Annual Fuel Utilization Efficiency and is the efficiency rating of the model shown. Unlike steady-state conditions, this

rating is based on average usage, including on and off cycling, as set out in the standardized Department of Energy test procedures.

REMEMBER: The higher the AFUE rating, the more efficient the model will be. 12. Electrically Efficient Furnaces (e) - The bold, italicized “e” designates furnaces that meet GAMA’s guideline for electrical

efficiency. The guideline applies to furnaces whose electricity consumption is 2% or less of the furnaces total energy use, according to the Department of energy’s official test procedure, and is determined according to the following formula:

(Eae x 3413) / [(Eae x 3413) + (Ef x 1,000,000)] ≤ 2%

Such furnaces typically employ a more efficient motor on the circulation fan and can significantly reduce electricity use during the

heating season compared to models of the same AFUE and capacity that do not meet the guideline, especially when the circulating fan is operated on its own for ventilation, air circulation, or filtration. The electricity saved during each heating cycle is offset, on a site energy basis, by an equivalent increase in fuel use.

The guideline does not ensure electricity savings during the cooling season. For cooling season electricity savings, specify a

furnace-air conditioner combination with a Seasonal Energy Efficiency Rating (SEER) that exceeds the federal minimum. 13. Primary heat exchanger material (boilers only). Notes: a) Items 7 and 11 are certified values, while items 8, 9, and 10 are provided for application use. b) Eae and Ef are based on national averages. For the purpose of comparison, use the calculation procedure in this section. Procedure for Estimating the Annual Heating Requirements and Comparing the Costs of Operation of Different Models

To estimate the amount of energy a home will use to provide comfort heating for a year, it is necessary to use both a) information specific to the particular home's need for heat, and b) the size and efficiency information on models listed in this Directory. Outlined below is a method (based on the Department of Energy efficiency test procedure for furnaces and boilers) for first estimating the annual amount of energy used for heating a specific installation and then making a comparison of the estimated annual operating costs of models of essentially the same size but different efficiencies. Because of the number of variables involved in the procedure, the method shown here is only for the purpose of 1) estimating the amount of energy that will be consumed in one year for the specific installation and 2) comparing models of various Annual Fuel Utilization Efficiencies (AFUE) to assist in making a purchasing decision. The method outlined below can be used for comparing models using the same fuel (gas to gas) or different fuels (gas to oil). When selecting models for comparison, make sure units are of the same configuration needed for a particular installation, i.e., upflow models, etc. A "Worksheet" is provided at the end of the section for ease in compiling and calculating the necessary information. The steps required to complete the "Worksheet" are: Step 1 - Determine the Heating Load Hours (HLH) for your area. To find an approximate number of Heating Load Hours for your specific

area, use the map illustrated in Figure 1.

Heating Load Hours, HLH hours

The procedure outlined above is based upon the Department of Energy test procedure for estimating the annual operating cost

of gas or oil-fired furnaces or boilers. It includes the cost of annual fuel usage (natural gas, propane gas, or No. 2 heating oil), in addition to the annual electrical cost to operate furnace circulating blowers, pumps, and power burners.

Step 2 - Estimate the Design Heating Requirement (DHR) for the specific installation. Because the Design Heating Requirement is

dependent upon a number of variables, such as the size of the house, building materials, insulation, architectural features, specific climatic conditions, etc., this determination must usually be performed by a knowledgeable heating contractor or other qualified source.

Design Heating Requirement, DHR Btu/hr

Step 3 - Refer to the Directory to identify the size of the model needed to satisfy the Design Heating Requirement determined in Step 2.

Models listed in the Directory of essentially the same heating capacity can now be evaluated for estimated annual operating costs. Models of the same fuel type (gas versus gas) as well as different fuel types (gas versus oil) can be compared using this

Step 4 - Determine the Rated Design Heating Requirement, RDHR, for the selected model. The RDHR for an appliance is the DHR

value that was used to calculate the Ef and Eae ratings included in this Directory. Using the Heating Capacity from Step 3, read the RDHR from Table 1.

Step 7 - Calculate the Estimated Annual Electrical Usage, EAEU, for your specific installation.

EAEU = AF x Eae where, AF = Adjustment Factor from Step 5. Eae = Average Annual Electrical Consumption from Step 3.

Step 8 - Calculate the Estimated Annual Operating Cost, EAOC, for your specific installation and selected model.

SEPTEMBER 30, 2008 PAGE 6

EAOC = [(EAFU x 1,000,000 x Fuel Cost) / Btu Content] + (EAEU x Electrical Cost)

where, EAFU = Estimated Annual Fuel Usage in MMBtu from Step 6. 1,000,000 = Conversion factor for MMBtu to BTU. Fuel Cost = Cost of fuel for your area in: $ per therm for Natural Gas $ per gallon for Propane Gas. $ per gallon for Heating Oil. Btu Content: 100,000 Btu per therm for Natural Gas. 91,333 Btu per gallon for Propane Gas. 138,700 Btu per gallon for Heating Oil. EAEU = Estimated Annual Electrical Usage in kW-hr from Step 7. Electrical Cost = Cost of electricity in your area in $ per kW-hr.

EAOC, $ per year

This procedure can be repeated for other models of essentially the same size with different efficiencies to compare their Estimated Annual Operating Costs. Models with higher efficiency (AFUE) ratings will consume less fuel and cost less to operate, but generally have a higher purchase price and may have a higher installation cost. Therefore, there is a period of time, referred to as a "Payback Period", before the savings that result from the lower operating costs of a more efficient model makes up the difference in price of that furnace or boiler as compared to a less efficient model. EXAMPLE: Assume you are intending to buy a new gas furnace and have calculated the Estimated Annual Operating Cost (EAOC)

using the procedure outlined above for two models of essentially the same size to meet your heating requirements but with different efficiency (AFUE) ratings.

Price of Furnace AFUEEstimated Annual Operating Cost

Model A $600 Installed 78% $425.00 Model B $775 Installed 91% $365.00

The additional cost of more efficient model (Model B) is: $775 - $600 = $175 higher installation cost. The estimated Annual Savings in Operating Costs for Model B, as compared to Model A is:

$425 - $365 = $60 lower operating cost per year. The payback period is:

$175 / $60 per year = 2.92 years = 35 months

SEPTEMBER 30, 2008 PAGE 9 INFORMATION ABOUT THE GAMA FURNACE AND BOILER EFFICIENCY CERTIFICATION PROGRAM Testing Laboratory and Test Procedures Intertek Testing Services of Cortland, New York, has been retained as the program’s designated independent testing laboratory responsible for conducting efficiency verification tests on furnaces and boilers. Randomly selected units of gas and oil furnaces and boilers are tested in accordance with the U. S. Department of Energy Test Procedures for Furnaces and Boilers as published in the May 12, 1997 Federal Register Notice and amended in the October 14, 1997 Federal Register Notice. Some boilers listed in the GAMA Directory have been tested under the boiler verification program sponsored and conducted by the Hydronics Institute (HI), a section of AHRI. Cross listing between the two programs is permitted. Scope of the Program The program is open to all manufacturers of furnaces and boilers and to all firms that market private brand models. Participation in the program is voluntary, but all models of furnaces and boilers sold by a participant in the United States must be included in the Efficiency Certification Program. The furnaces and boilers covered by this program are defined by the following parameters:

a) All furnaces, including manufactured housing (mobile home) furnaces, with input ratings less than 225,000 Btu/hr that use single-phase electric current or DC; and

b) All boilers with input ratings less than 300,000 Btu/hr that use single-phase electric current or DC. The Directory and the Federal Trade Commission Energy Guide Label Program The Federal Trade Commission (FTC) requires that furnaces and boilers be labeled to show how the efficiency of these models compare to other comparable models. This FTC required EnergyGuide label also directs the consumer to a fact sheet or directory containing specific energy efficiency and operating cost information. This is the directory to which that statement refers. The sample FTC EnergyGuide label on the following page has explanations as to how the listings in this directory complement the information provided on the label.

SEPTEMBER 30, 2008 PAGE 10

CORRELATION OF CHAPTER 1 LISTINGS TO FTC “ENERGY GUIDE” LABEL

The model number(s) for all models to which the label applies are listed. The model numbers is given in the first column of the listing. This is the measured AFUE of this model. This section shows how this model compares to all other similar models that use gas.

Note: the sample FTC “Energy Guide” label is shown for a gas furnace. A similar label is required for oil furnaces and gas and oil boilers. Also, some furnaces can be installed in one of the three positions (i.e. upflow, horizontal, or downflow). The number of positions that a particular furnace model can be installed will determine whether its label may have one, two, or three range bars.
