Clearances To Combustibles; Combustible Mantel Clearances - Regency U31 Owners & Installation Manual

INSTALLATION
The clearances for the Zero Clearance Kit are 0" to combustibles (back, side and floor) but when planning your installation
review the clearances required for the Insert (see below) after it is installed in the Zero Clearance Kit. The Zero Clearance Kit
must be installed on a flat, solid, continuous surface (e.g. wood, metal, concrete). This may be the floor, or raised up on a platform
to enhance its visual impact.
NOTE: The specified '0' inch floor clearance means that the top surface of the flooring material, i.e. carpeting, tile, etc.,
must not extend above the bottom edge of the 4" Hearth Trim.
