Figure 3.21 Vinyl Flooring Recommendations Note: Finished floor thickness should also be considered when determining installation dimensions. 4 E. Vinyl Flooring Vinyl flooring is sensitive to heat. To avoid damage to the vinyl flooring, a 12 inch minimum x 12 inch minimum hearth is recommended when using vinyl flooring up to the wall. See Figure 3.21. If no hearth is used, it is recommended to provide a minimum of 30 inches of clearance in front of the appliance to the vinyl flooring OR the bottom of the appliance should be raised a minimum • of 24 inches off of the floor to allow the vinyl flooring to be installed up to the wall. NOTICE: Clearances that do not meet the minimum guidelines could result in damage or buckling to the vinyl flooring and is done at the installer's risk. Hearth and Home Technologies does not recommend VINYL adhesive based vinyl flooring products due to thermal 24 IN. MIN. expansion during operation. Floating style flooring can be used, but will reach temperatures up to to 110 °F (based on ambient temperature of 70 °F). Consult the manufacturer's flooring specifications to ensure compatibility.
