it is entirely permissible to extend noncombustible facing materials beyond those limits to achieve a particular decorative effect.
5.Despite the most careful planning and the latitude provided by the maximum and minimum opening dimensions, it still may be necessary to cut some tiles to achieve a balanced appearance. Your tile supplier or local tool rental outlet should be able to supply the necessary equipment and explain how to use it properly.
Consult your Vermont Castings dealer for advice and suggestions for this process.

Be sure the height of the side pieces is between 29” (740 mm) and 33¹⁄₄" (845 mm), and that the thickness of backing, adhesive, and stone combined is not more than 13/16" (20 mm).

1.Draw the maximum and minimum fireplace open- ing dimensions on a large sheet of cardboard.
2.Place it on the floor and experiment with laying the tiles around the opening, varying within the limits to determine the best arrangement.
3.Trace and cut out a silhouette of the insert. Lay it over the tiles to show how the insert will cover the tiles when it is installed.
4.On another large piece of cardboard, cut an opening to represent the limits for combustible material, and position that on top of the tile lay- out. Keep in mind that while combustible material must not be brought inside the combustible limits,

Use the Right Adhesives
The adhesive must be suitable to the chosen mate- rial and have a temperature rating of at least 400°F (204°C). High temperature silicone is an example.
Maintain a Safe Clearance to the Mantel
The clearance to the mantel and/or top trim must be at least 43” (1090mm), measured from the finished hearth surface. This clearance cannot be reduced by adding shields.
