### APPENDIX E. ENGINEERING ANALYSIS COST AND EFFICIENCY TABLES

E.1 INTRODUCTION This appendix contains the cost and efficiency tables described in Chapter 6, section 6.7.4 of the Furnace and Boiler Technical Support Document (TSD). The Department based the payback periods on the calculation methodology found in the DOE furnace/boiler test procedure; these payback periods may differ from those found under field conditions. For the final rule, the Department included an extra cost for Weatherized Gas Furnaces to reflect the cost of the stainless steel heat exchanger at 82% and 83% AFUE and for Gas Boilers to reflect the cost of the draft inducer for installations that require Category III venting. Tables E.1.3 to E.1.6 and Tables E.l .11 to E. 1.14 provide the results using low and high values for these additional costs. Section 6.4.1.2 in Chapter 6 provides further details regarding these changes.
