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.
