CHIMNEY DIAMETER:
Follow the fireplace manufacturer’s manual to
determine required chimney diameter and clearances
between combustible materials and your fireplace.
Never use a chimney with an inside diameter smaller
than your firebox flue opening unless specifically
allowed by the fireplace manufacturer.
CHIMNEY ENCLOSURE REQUIREMENTS:
Interior chimneys shall be enclosed where they
extend through closets, storage areas, occupied
spaces, or anywhere the surface of the chimney could
be contacted by persons or combustible materials.
The air space between the outer wall of the chimney
and the enclosure shall not be less than 2 inches.
WARNING: Do not place any type of insulation or
other materials in the required clearance spaces
surrounding the chimney assembly.
Except for installation in one or two family dwellings,
a factory built chimney that extends through any
zone above that on which the connected appliance is
located is to be provided with an enclosure having a
fire resistance rating equal to or greater than that of
the floor or roof assemblies through which it passes.
In cold climates, chimneys mounted on an outside wall
should be enclosed in a chase. Exterior chases reduce
condensation, creosote formation and enhance draft.
Chimney components intended for exterior
installation must be marked “
Suitable for Interior or
Exterior Installation
”.
INSTALLATION RECOMMENDATIONS:
Proper planning for your EC
O
-Steel Air-Cooled and
Insulated Chimney installation will result in greater
safety, efficiency and convenience. You must use
only EC
O
-Steel Chimney parts and components
to maintain a listed chimney system. Do not mix
EC
O
-Steel Air-Cooled and EC
O
-Steel Insulated
Chimney parts or try to match with other products or
use improvised solutions.
Install your fireplace as described by the
manufacturer’s installation instructions and maintain
all required clearances. Acceptance of the assembly
is void if the installation instructions are not followed.
Connect only one fireplace per chimney. Follow the
fireplace safety manual for maximum efficiency and
safety. Do not over fire. Any damage to the fireplace
or chimney can possibly void the warranty.
Do not burn driftwood, plastic, or chemically treated
wood such as railroad ties. They are corrosive to your
chimney system. Follow the fireplace manufacturer’s
instructions regarding fuel.
ISOKERN FIREPLACE INSTALLATION:
Place Fireplace:
Position according to the fireplace
manufacturer’s installation instructions. The flue outlet
should be placed between the rafters or joists above,
if possible.
Determine Chimney Size:
Follow the fireplace
manufacturer’s instructions for chimney size.
Mount Anchor Plate:
Chimneys for Isokern fireplaces
with EC
O
-Steel begin with an Anchor Plate or Anchor
Plate with Damper.
It is important that the surface of the Isokern chimney
has a level surface on which to attach the Anchor Plate.
If the top of the Isokern does not have a level surface,
then it will need to be modified accordingly. Center
the Isowool blanket over Isokern Top Plate hole and
trace outline of hole with a pen or marker. Cut a hole in
the blanket to match the hole in the Isokern top plate.
Center the Isowool blanket over the Isokern Top Plate
flue opening, then center anchor plate over the Isowool
blanket. If a Damper is used, make sure nothing
interferes with the damper plate movement. Secure
the Anchor Plate with four (4) masonry anchors. See
FIG.1
. If the Anchor Plate with Damper is installed the
damper should swing freely. When the chain is pulled
down, the damper should close (horizontal position).
When the chain is released (no weight on the chain),
the damper should swing open (vertical position). To
install the lintel hook, place the damper plate in the
closed (horizontal) position. Determine and mark the
position of the lintel hook. The lintel hook should be
mounted in a position so as to provide a small amount
of tension in the spring attached to the chain. See
FIG. 1
. The tension is needed to prevent the damper
plate from rattling when closed. Mount the lintel hook
to masonry with the screws provided. Do not obstruct
openings in the anchor plate.
Warning: Do not locate Anchor Plate with Damper in
a location inaccessible for inspection, cleaning and
servicing after installation.
