Ovens can be located directly on the floor or elevated on support platform. A floor-mounted oven with product openings in the sidewall should feature some method of heat containment and the floor should be insulated to reduce heat loss. Elevated ovens reduce heat loss and save floor space. An elevated oven can cost more than a floor-mounted oven because of increased installation costs and additional materials. Bottom entry and exit openings in an elevated oven will provide the best possible heat containment.
