CLEARANCES TO COMBUSTIBLES

Floor protector must be 3/8” (10mm) thick minimum noncombustible material or equivalent, extending beneath heater and to the front/sides/rear as indicated in the ‘‘Floor Protection’ (See Figure 5).

FIGURE 5. Clearance to Combustibles (UL AND ULC)

Note 1: 6" (152mm) diameter single wall, minimum 24 MSG black or blued steel connector pipe with a listed factory-built type HT chimney suitable for use with solid fuels or a masonry chimney.

Note 2: 6" (152mm) diameter double wall air cooled connector pipe with listed factory-built type HT chim- ney or a masonry chimney. (Mobile home venting sys- tem must be equipped with a rain cap and spark ar- restor.) For installations with a preexisting class A chimney system, a listed stainless steel chimney liner should be installed, or the existing chimney exam- ined by a chimney sweep for acceptable further use.

Note 3: Alcove specifications: Maximum depth of al- cove shall be no more than 48" (1219mm). For addi- tional alcove information and clearances, refer to clearances to combustibles above.

NOTE: Unit is approved for use with listed double wall air-insulated chimney connector or elbows.

When locating your stove consider safety, conve- nience, traffic flow, and the fact that the stove will need a chimney and chimney connector.

NFPA 211: Use a noncombustible material with 1” (25mm) ventilated air space to reduce clearances. However, this is not to exceed 50% of WS-150’s (or WS-250’s) specified clearances.

NOTE: Must follow NFPA 211 spacing and materials to qualify. It is also subject to local jurisdiction.

AVOID FIRE: Maintain the designated clearances to combustibles. Insulation must not touch the chimney. You must maintain the designated air space clear- ance around the chimney. This space around a chim- ney is necessary to allow natural heat removal from the area. Insulation in this space will cause a heat buildup, which may ignite wood framing.
