NOTE: The stated installation clearances provide the safest distance for combustible materials to
ensure that walls, ceilings and mantle components will not be affected by heat discoloration,
warpage, or possible fire. Each appliance installation presents a different set of variables which
can create problems beyond the control of the gas log manufacturer. It is the responsibility of
the installer to stay within the minimum clearances stated and set forth by the manufacturer
within this instruction manual.
