To give your fireplace that contemporary look a lot of clients are going with glass instead of wood. Adding glass to your fireplace gives it an elegant look that provides it with a real sparkle. If you decide to go this way be sure you purchase the glass from a professional as it is not just any glass. It must stand up to the extreme heat of the fire without causing damage. You must also use the correct burner pan. Make sure your fireplace can withstand the amount of BTUs the burner will produce. I recommend you get your fireplace cleaned and inspected by a professional prior to installing any gas appliance. If you use the right professional he or she will be knowledgeable about these things. You will be pleased with the elegant, beautiful focal point in your home. The fireplace will provide you with many years of pleasure with very minimal maintenance.
