PLANNING YOUR INSTALLATION

COMBUSTIBLE WALL CLEARANCE

WARNING: IT IS VERY IMPORTANT THAT YOU OBSERVE THE MINIMUM CLEARANCES.

There are listed clearances for your stove which were determined in a Laboratory test using various "classes" of stove pipe or chimney. Minimums are first estab- lished for the stove itself and increased based on how much heat is transferred by each class of pipe.

Note: Manufactured (mobile) home installations require the use of a Type L Vent Chimney connector only. Use of a single wall flue pipe connection is not permitted.
