8.3 Reducing Wall and Ceiling Clearances Safely
It is often desirable to reduce the minimum installation clearances by placing the stove closer to
walls so the installation takes up less floor space. You can safely reduce the minimum clearances
by permanently installing a shield between the stove and combustible material. The rules for
safe shields can be complicated, so read them carefully and follow them exactly. Note that there
may be minor regional differences in clearance reduction rules so be sure to check with your
building or fire inspector before proceeding.
