B-Vent Metal Chimney - General Information
The Maximus Linear Series See-Thru Fireplaces are tested and listed for use only with the specified factory-built metal B-
Vent chimney system as detailed in this manual. All Maximus Linear fireplace systems require 12” Metal-Fab Type-B Gas
Vent Chimney System with Anchor Plate with Down-Draft Diverter.
APPROVED MANUFACTURERS
Metal-Fab® (UL 441 & ULC S605) Type B Gas Vent
NOTE:
The selected, approved chimney manufacturer must provide the masonry anchor plate with down draft diverter
designed to fit their flue system.
All chimneys and chimney liners must be installed in accordance with the manufacturer’s installation instructions and under
the terms of their listing.
Refer to metal flue manufacturer instructions for information regarding the number of offsets allowed, approved chimney
shrouds, clearance to combustibles, and or any information specific to that flue system. B-Vent Chimney is not designed for
use on products that operate at continuous temperatures exceeding in excess of 1000°F.
IMPORTANT
: Never fill any required clearance space with insulation or any other building materials surrounding the
chimney. B-Vent chimney pipe requires one (1”) air space clearance. Do not place any material within the required one (1”)
clearance zone. The vent pipe listing may be voided if the clearance requirement is not adhered to.
Exterior metal parts of the chimney, with exception of the mechanical draft components, 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 routed outside of the building should be enclosed in a chase. Exterior chases reduce
condensation and enhance draft.
Proper planning for your B-Vent Chimney installation will result in enhanced safety, efficiency, and convenience. You must
use only B-Vent Chimney parts and components to maintain a listed chimney system. Do not mix parts or try attempt 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 food, wood, driftwood, plastic, or chemically treated wood such as railroad ties. They are corrosive to your chimney system.
Use of any fuel other than gas on burner rating plate will void the warranty of this fireplace and is prohibited
. THIS IS A GAS ONLY
FIREPLACE

IMPORTANT: A major cause of chimney related fires is failure to maintain required clearance (air
spaces) to combustible material. Minimum clearance for 12” diameter B-vent chimney is one (1)
inch. It is of utmost importance that this chimney system is installed only in accordance with these
instructions.
