I am not sure if the European approval number would be acceptable. Following, I have included a link to an article that states, "Before you buy, make sure a wood stove meets local air quality regulations. As a rule of thumb, the more efficient the stove, the less pollution it produces. Check with your local air pollution control district
to see if there are regulations covering how efficient your stove must be." The EPA also has specific "approved" items that may or may not include the proposed stove. http://www.consumerenergycente...ling/fireplaces.html
Hope this information helps.
