Figure 13.13 Inside Fit Method (Tonic Decorative Front Only)
Non-Combustible Finish Materials
0 in. to 4 in. (0 mm to 102 mm) Thick Inside Fit Method
The Tonic decorative front is approved for inside fit ap-
plications. Non-combustible finishing materials up to 4
in. (102 mm) thick can be installed around the front (left,
right, top, and bottom).
For the Tonic decorative front inside fit applications, the
decorative front must be installed tight to the finishing
flanges and must not overlap any finish material.
Ensure that no non-combustible finish materials are in-
stalled within 3/4 in. (19 mm) of the fireplace opening.
The 3/4 in. (19 mm) spacing is required to provide clear-
ance for removing and installing the Tonic decorative
front. See Figure 13.14.
