Install the Heatizon Marker Plate to indicate the presence of a Heatizon embedded snow melting system. This will help avoid damage from future site work. Install the Heatizon Marker Plate where clearly visible in each area that has embedded heating elements. The Heatizon Marker Plate is placed flush in a wet concrete surface or soft asphalt surface or by other means for surface attachment. Other types of surfaces should be made to allow the marker plate to be installed flush with the surface. Do not damage the heating element.
