The Magnum 86072 Series fireplace and the DM
chimney system is tested and listed for installation with “clearance
to combustibles” as follows:
All DM 44 and 54 chimney components require 0”
clearance. (Figure 2).
The Magnum 86072 Series firebox side walls and back
wall require 1-1/2” clearance. (Figure 3)
The smoke dome front wall requires 0” clearance.
Note: “Combustibles” are defined as “normal construction
materials” and are considered to be: wood framing materials,
particle board, mill board, plywood sub-flooring, plywood
paneling and wood flooring.
Sheathing materials, such as plywood, particle board
and drywall may cover the smoke dome front at 0” clearance.
All combustible sheathing materials that protrude beyond front
of firebox must be held 9” away from the sides of the firebox
opening and 24” above the top of the firebox opening. Drywall
must be cut 9” back from the firebox opening sides and 24” above
the top of the opening.
Keep all insulation, vapor barriers, “house wrap” paper and
other insulating type membranes and products, including
fiberglass, cellulose and other insulation, (anything that
carries an “R” rating) a minimum of three inches (3”) away
from all firebox and chimney surfaces. See exception.
Exception:
If insulation is used in walls surrounding the fireplace,
insulation may be installed behind sheathing of gypsom board,
plywood, particle board or other material on the side facing
the Isokern. The facing material cannot be within 1 1/2” to the
fireplace sidewalls.
Notes: A. The Magnum 86072 Series fireplace must sit upon a
concrete support slab designed to bear the total installed weight
of the fireplace and DM chimney system. These support slabs
can have no wood underpinnings. (Figure 3)
B. Concrete support slabs for Magnum 86072 Series
fireplaces must provide the noncombustible hearth extension
substrate needed to support the code required noncombustible
hearth extension finish materials. (Figures 2 and 3)
C. All Magnum 86072 Series fireplaces shall have
hearth extensions of approved noncombustible material such as
brick, tile, or stone that is properly supported and with no com-
bustible material against the underside thereof. Wooden forms
used during the construction of hearths and hearth extensions
must be removed when the construction is complete.
D. If a raised fireplace floor and raised hearth exten -
sion are preferred, the raised underlying structure must be built
of noncombustible material, be structurally designed to hold
the weight of the fireplace and chimney system and must sit on
noncombustible substrate.
