cLeaRances & non-combustibLe :
When installing the C60I as a zero clearance replace the correct clearances and materials must be used:
aboVe unit: A minimum 13 3/4” (350mm) of non-combustible facing material must be used above the
rebox opening.
in FRont oF unit: The C60I can be placed on a combustible oor if desired. The unit cannot sit directly
on combustible ooring other than wood.
aDjacent/siDewaLL: A minimum of 5 3/16” (132mm) of non-combustible facing materials must be used
of the side of the rebox opening above the bottom edge openeing. There must be a minimum distance of
7” (229mm) from the nishing edge of the C60I to an adjacent wall composed of combustible material.
mantLe: It is not necessary to install a mantle, but if one is desired the guidelines as shown in Figure
30(a,b). The minimum clearance from the side of a mantle to wall is 4”.
FLooR: There must be a minimum distance of 10” (254mm) from the bottom nishing edge of the C60I
to a oor composed of combustible material.

cRacking: The most common area of cracking is along the horizontal cement board/drywall
transition; placing this transition further away from the heat will help prevent cracks. If you
have concerns of excessive nishing wall temperature follow one of these options to mini-
mize the possibility of cracking:
1. Install the optional heat distribution kit (50-3213).
2. Install concrete board higher than the minimum specied dimension.
3. Add a decorative tile trim over the drywall transition area.
