IMPORTANT:
The manufacturer is not responsible for installation and use practices that are beyond the scope of the
product as defined in the product listing and in this installation manual.
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:
Models 28, 36, 42, and 48 (see Figure 2):
• Sides: 8" away
• Top of opening: 8" away
Drywall must be cut back from the firebox opening sides and above the top of the opening according to information
above.
EXCEPTION:
If insulation is used in walls surrounding the fireplace, insulation may be installed behind sheathing of
gypsum board, plywood, particle board or other material on the side facing the Isokern. The facing material cannot be
within 1½” to the fireplace side walls.
The MAGNUM 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)
.
See page 18 for more information on weight loads.
Concrete support slabs for MAGNUM Series fireplaces must provide the non-combustible hearth extension substrate
needed to support the code required non-combustible hearth extension finish materials
(Figure 4)
.
All MAGNUM Series fireplaces shall have hearth extensions of approved non-combustible material such as brick, tile,
or stone that is properly supported and with no combustible material against the underside thereof. Wooden forms used
during the construction of hearths and hearth extensions must be removed when the construction is complete.
If a raised fireplace floor and raised hearth extension are preferred, the raised underlying structure must be built of
non-combustible material, be structurally designed to hold the weight of the fireplace and chimney system and must sit
on non-combustible substrate.
