The metal floor of the ZC solid fuel firebox can be removed to allow the installation of the insert. THE
CLEARANCE TO COMBUSTIBLE MATERIAL UNDER THE INSERT IS ½” (13mm). YOU MUST USE THE
LEVELING LEGS TO RAISE THE INSERT A MINIMUM OF ½” (13mm) IF THE UNIT IS TO BE INSTALLED
ON COMBUSTIBLE MATERIAL. The sidewalls and top structure of the solid fuel firebox cannot be altered
with the exception of removable dampers and baffles. THE ORIGINAL FIREPLACE MAY NEVER BE
RETURNED TO SOLID FUEL USE IN THIS CONDITION.
IMPORTANT: If the factory-built fireplace has no gas access hole(s) provided, an access hole of 1.5 inch
(37.5 mm) or less may be drilled through the lower sides or bottom of the firebox in a proper workmanship
like manner. This access hole must be plugged with non-combustible insulation after the gas supply line
has been installed. Cutting any sheet-metal parts of the fireplace, in which the gas fireplace insert is to
be installed, except as tested for the floor is prohibited.
