Installation—General
When a metal prefabricated chimney is used, the manufacturer's installation instructions must be followed precisely. You
must also purchase (from the same manufacturer) and install the ceiling support package or wall pass through and "T"
section package, fire stops (when needed), insulation shield, roof flashing, chimney cap, etc. Maintain the proper
clearance to the structure as recommended by the manufacturer. This clearance is usually a minimum of 2 inches,
although it may vary by manufacturer or for certain components.
There are basically two methods of metal chimney installation. One method is to install the chimney inside the residence
through the ceiling and the roof (Fig. 17 and 18). The other method is to install an exterior chimney that runs up the
outside of the residence (Fig. 19 and 20). The components illustrated may not look exactly like the system you purchase,
but they demonstrate the basic components you will need for a proper and safe installation.
The chimney must be the required height above the roof or other obstruction for safety and for proper draft operation.
The requirement is that the chimney must be at least 3 feet higher than the highest point where it passes through the
roof and at least 2 feet higher than the highest part of the roof or structure that is within 10 feet of the chimney, measured
horizontally (Fig. 12).
THIMBLE
When a wall exit installation is used, a listed assembly thimble must be installed. In a roof exit installation, the ceiling
support box supplied with the manufactured chimney acts as a thimble.
REMEMBER: Follow the manufacturer's installation instructions and maintain the manufacturer's specified
clearance distances.
Install an attic insulation shield to maintain the specified clearance to insulation. Insulation in this air space will cause a
heat buildup which may ignite the ceiling Joists
The “Through The Roof” method of installation requires at a minimum a ceiling support package, an Insulation shield and
roof flashing.
The “Through The Wall” method requires at a minimum a wall pass through device, a wall support package and
insulated “T” section and roof flashing.

Due to the high efficiencies of these units, Blaze King recommends the use of
double wall pipe from the stove top to roof or wall exit.
