8.5.1 Reducing Wall and Ceiling Clearances Safely
Existing clearances to combustible materials around the masonry hearth may be different
clearances from a certified insert. It is possible to safely protect combustible materials that
have clearances less than those required for the insert CW2500. Simply attach
permanently a shield on flammable materials. The rules for shields are sometimes
complicated, read and follow them carefully. Note that there may be slight regional
differences in the rules to reduce clearances, check with your local building inspector or
fire protection before starting.
8.5.2 Shield construction rules
See figures Clearances for wall and ceiling shield construction and Clearances for
top surround, side surround and shelf shield construction to match each letter to a
clearance.
- Mounting hardware which extends from the shield surface into combustibles may be
used only at the edges of the shield.
- Mounting hardware must allow full vertical ventilation.
THESE SAME REQUIREMENTS APPLY TO THE TOP SURROUND, SIDE SURROUND
AND SHELF.
