ABSTRACT:
Resurfacing or conditioning of the ice surface of an ice rink in the area adjacent the edge of the ice and the kickboards defining the edge of the ice is carried out by a burner unit which applies a propane flame in a direction downwardly onto the ice in an area confined by a metal guide surrounding the flame. The unit melts the ice on the board and at the edge to prevent ice build up using a simple economic construction on a device which produces little or no toxic fumes.
