DM 54 Chimney: Component Weights

Isokern DM Chimney Weights:

Total installed Isokern DM chimney weight will vary

according to each specific installation. Total installed chimney

weight will be based on the overall height and the configuration of

the chimney system.

Chimneys may be straight vertical stacks of DM 54

outer casing and inner liner but may also include the use of offset

chimney blocks, brickledge, chimney reinforcement, brick/stone

veneers, cement crown caps and clay chimney pot termination.

The DM 54 chimney component weights are as follows:

Small crown cap: 80 lb.

Large crown cap: 100 lb.

Brickledge: 110 lb.

14” diameter inner liner: 40 lb.

Outer casing block: 90 lb.

Offset block*: 110 lb.

*Construction of an offset block sequence will shift a portion, if

not all of the chimney load off of the firebox and smoke dome.

Additional reinforced concrete footing and slab area may need to

be provided adjacent to or as a continuation of the primary support

slab area for bearing the steel or masonry support required for an

offset sequence. (See pages 47 - 50 following.)

Notes:

Plan chimney configuration carefully before constructing

the required reinforced concrete support foundation for the

MAGNUM fireplace. Be sure that enough structural masonry area

is available to support any offset chimney sequence included in

the proposed chimney design.

Isokern is not responsible for site specific structural

support details and load specifications for MAGNUM fireplace

and DM chimney system installations. Consult local structural

engineer for proper job-specific support structure design, sizing

and load bearing specifications.

Unless otherwise noted, all floor drawings in this manual

are merely illustrations to indicate the presence of an underlying

noncombustible support structure to the MAGNUM installation.
