The chimney system must be installed, by a qualified chimney or venting professional, according to these

installation and maintenance instructions. Read through and become familiar with these installation
instructions before installing this product. Failure to follow these instructions may void the
manufacturer’s warranty, the UL listing status of this product, and may result in a hazardous
installation.

Keep these instructions for future reference.

Codes & Permits

The criteria for installation must be in conformance with the specifications contained in the latest version of the
NFPA 211 (Standard for Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances) and local or state
building codes, whichever has jurisdiction. Contact local building or fire officials about restrictions and
installation inspection in your area. It may be necessary to obtain permits before installing the chimney system.
ALWAYS CONTACT YOUR LOCAL BUILDING OFFICIAL OR FIRE OFFICIAL REGARDING
PERMITS, RESTRICTIONS AND INSTALLATION INSPECTIONS IN YOUR AREA.

Product Applications

The Ventis Class-A Chimney system is intended for use with heating appliances utilizing solid fuels, oil, gas
(natural or propane) and coal. This includes, but is not limited to, the following appliance types: free standing
wood stoves, wood stove inserts, fireboxes, fireplaces, furnaces, boilers, stoves, ranges or water heaters that
require a UL103 chimney system. Ventis Class-A is not listed, nor intended, to be installed with forced draft or
positive pressure heating appliances.

Termination Above the Roof

The termination of the Ventis
Class-A chimney system must be

in accord with the NFPA 211
codes. This code requires that a
chimney terminate at least 3 feet
above the point where it penetrates
the roof and 2 feet higher than any
structure within a 10 foot radius.
The maximum height of an
unsupported chimney above the
roof line is 5 feet. Chimney
heights greater than 5 feet above
the roof line must use and
extended roof brace.

General Specifications

Clearances

A minimum 2 inch airspace must be maintained between the exterior of the Ventis Class-A chimney system and
combustible materials or as established by factory built supports and firestops. Ensure that building insulation,
electrical wiring and/or any other combustible materials do not violate the required 2-inch airspace clearance.

The clearance between single wall connector pipe (VENTIS BLACK™ SINGLE WALL STOVEPIPE) and
unprotected combustible material must not be less than 18-inches (See latest version of NFPA 211). The
distance between the vertical single wall stove pipe and the ceiling may be less than 18-inches depending on the
specifications of the finishing support.

Note:

Except for the installation in one and 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.

All interior portions of the chimney must be accessible for inspection and cleaning.

For installing the chimney system in a chase application, the chimney must extend a minimum of 6-inches above
the chase cover.

Sizing the Chimney Systems

Always size the chimney liner in accordance with the appliance manufacturer’s instructions. Keep in mind that

the outside diameter will be 2 1/2-inches larger than the inside diameter.
The Ventis Class-A chimney system may be installed to a maximum height of 40 feet.

Additional Considerations

It is recommended, in colder climates, that exterior mounted chimney systems are enclosed to help reduce or

limit condensation, creosote build-up and poor draft.

Approved Installations

Use of any parts or materials not specified in this installation manual may not provide a listed system and may
void the Ventis Class-A warranty. Do not attempt matching Ventis components or pipe sections with another

manufacturer’s products. Do not use damaged or modified parts.

Safety Considerations

Caution: The ends of the chimney sections, edges of the cap, roof flashings, tee and other components
can be sharp! We strongly recommend the use of gloves during installation.
Warning: Watch out for overhead power lines during installation. Be sure to check above and around
the chimney for antennas, power lines, or any other obstacles before beginning the installation. Be sure
that the chimney does not come in contact with electrical or any other wires.
