Proposal: Step 1 in 2014 for large manufacturers; Step 1 in 2019 for small manufacturers

Alternative (same as Proposal): Step 1 in 2014 for large manufacturers; Step 1 in 2019 for small manufacturers

*Note: The average 2008 base year cost per appliance was converted to 2010$ for this analysis. 2008 base year manufacturer price is provided in the Market Research and Report on North 

American Residential Wood Heaters, Fireplaces, and Hearth Heating Products Market prepared by Frost & Sullivan. April 26, 2010, p. 35.

**Analysis assumes that small manufacturers will purchase certification software in 2014, even if they take longer (until 2019), as allowed, to achieve the standard.
