The essential character test applies: if the primary design and marketing purpose is space heating and the cooktop is incidental, classification here is defensible. If the article is marketed and designed primarily as a cooking range that also heats the room, it would belong in the cooking appliance heading. Documentation of the manufacturer's intended use and product specifications supports the classification decision.

No — fuel type (wood, coal, pellet, or other solid fuel) does not change the classification within this heading, provided the appliance is nonelectric in its primary heating mechanism. An electrically powered pellet auger or igniter does not make the stove 'electric' for classification purposes if the heat source itself is combustion.
