NOTE: The selected, approved chimney manufacturer
must provide the masonry anchor plate with down draft
diverter designed to fit their flue system. (Figure 21)
All chimneys and chimney liners must be installed
in accordance with the manufacturer’s installation
instructions and under the terms of their listing for use
with open faced fireplaces.
Refer to metal flue manufacturer for number
of offsets, approved chimney shrouds, clearance to
combustibles and any information specific to that flue
system. Only tested and listed chimney terminations
can be used on metal flue chimney systems. B-Vent
Chimney is not designed for use on products that operate
at continuous temperatures in excess of 1000°F.
IMPORTANT: Never fill any required clearance space with
insulation or any other building materials surrounding the
chimney.
Exterior metal parts, with exception of the top
portion of the chimney cap, can be painted with a high
temperature rust proof paint. Wash the metal surface
with a vinegar and water solution to remove any residue
before painting. Painting the chimney will help to increase
chimney life.
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 1 inches.
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 and enhance draft.
Proper planning for your B-Vent Chimney installation
will result in greater safety, efficiency and convenience.
You must use only B-Vent Chimney parts and components
to maintain a listed chimney system. Do not mix parts

BVETTO B-Vent Gas Fireplace
B-Vent Metal Chimney Installation - General Information
or try to match with other products or use improvised
solutions.
Install your Isokern fireplace as described in this
installation manual and maintain all required clearances.
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 wood, driftwood, plastic, or chemically
treated wood such as railroad ties. They are corrosive to
your chimney system. THIS IS A GAS ONLY FIREPLACE.
A major cause of chimney related fires is
failure to maintain required clearance (air
spaces) to combustible material*. Minimum
clearance for 10” diameter air-cooled eco-
steel chimney is one (1) inches. It is of utmost
importance that this chimney is installed
only in accordance with these instructions.
