BW36 SERIES WOODBURNING FIREPLACE
No one builds a better fire
4. SIDEWALLS/SURROUNDS.
Adjacent combustible side walls must be located a minimum of 12" from the fireplace opening. See Figure 7. If you are using a decorative surround constructed of combustible material, it may be located within the shaded area defined in Figure 7. Short stub walls are also acceptable if they are contained within the shaded area.

5. MANTEL.
A combustible mantel may be positioned no lower than 12” above the top of the firebox opening. The combustible mantel may have a maximum depth of 12”. Combustible trim materials, projecting no more than 1 1/2” from the face of the fireplace, can be placed no closer than 6” from the top and side of the
firebox opening. (See the shaded areas on each side of the firebox, as defined in Figure 7). Combustible trim must not cover the black metal sur- faces of the fireplace. This mantel clearance is in accordance with Section
E. CHIMNEY REQUIREMENTS
When planning your fireplace location, the chimney construction and necessary clearances must be considered. The fireplace system and chimney components have been tested to provide the following flexibility in construc- tion. The following figures are the minimum distances from the base of the unit.
Minimum overall straight height | 14.5 ft. |
Minimum height with Offset/Return | 14.5 ft. |
Maximum height | 90 ft. |
Maximum chimney length between an Offset/Return | 12 ft. |
Maximum distance between Chimney Stabilizers | 35 ft. |
Double Offset/Return minimum height | 20 ft. |
Maximum unsupported chimney length between Offset/Return | 6 ft. |
Maximum straight unsupported chimney height above firebox | 25 ft. |
1. USING OFFSETS AND RETURNS.
To bypass any overhead obstructions, the chimney may be offset using a 15° offset/return (SL315) or a 30° offset/return (SL330). Perform the following steps to determine the correct chimney component combi- nation for your particular installation.
An offset and return may be attached together or a chimney section(s) may be used between an offset and return. However, the distance between two
elbows must never exceed 12 feet in total length.
a.Measure how far the chimney needs to be shifted to enable it to avoid the overhead obstacle. See Figure 8, dimension “A”.
b.After determining the offset dimension, refer to Table 1 (page 13) and find the “A” dimen- sion closest to but not less than the dis- tance of shift needed for your installation.
