COMBUSTIBLE WALL CLEARANCES

PLANNING YOUR INSTALLATION

COMBUSTIBLE WALL CLEARANCES

WARNING: IT IS VERY IMPORTANT THAT YOU OB- SERVE THE MINIMUM CLEARANCES.

There are listed clearances for your stove which were deter- mined in a Laboratory test using various "classes" of stove pipe or chimney. Minimums are first established 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.

Manufactured (Mobile) Home Standard and Residential Reduced - Using 6” (152 mm) diameter Type L-Vent connector pipe (to the top of the stove) with listed factory-built 103HT chimney suitable for use with solid fuels or a code approved masonry chimney. Approved brands of factory built chimney are Dura-Vent, Security, Jake Evans and Metal Bestos.

MANUFACTURED (MOBILE) HOME INSTALLATIONS MUST BE EQUIPPED WITH A RAIN CAP AND SPARK ARRESTOR.
