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.

PROTECTED WALL CLEARANCE

Some local codes will allow reduced clearances when the stove is installed adjacent to a protected wall system. The variance must be approved by your local building official. Normally, the protected wall system is defined as a non- combustible material with a minimum of 1" air space be- hind. Check your local building codes or with a qualified installer (Ref. NFPA 211).
