EN
Clean all ashes out of the inside of the existing fireplace opening. Make sure that the chimney and fireplace are free
of cracks, loose mortar, creosote deposits, blockage or other signs of deterioration. If necessary, have any repair
work done by a qualified professional before installing the insert.
Do NOT remove bricks or mortar from the fireplace. In case of an outside air inlet or ash dump, fill with fiberglass
insulation. Adhere to minimum clearances as illustrated.
Combustible material must not protrude more than 1" (25mm) to the side of the insert or between the mantel and
the top of the insert.
