CHIMNEY INSTALLATION

CHIMNEY INSTALLATION
A chimney performs two functions: it removes smoke and flue gases from the furnace, and it allows the
induction fan to provide the proper “draft” for the fire. Draft is the term used to describe the suction that
occurs when hot air rises and creates a vacuum in the firebox. The induction fan along with the chimney
draft draws fresh air into the firebox and feeds combustion of the wood. No furnace can operate properly
without adequate draft.
The following instructions are guidelines only. A qualified HVAC contractor should determine the specific
chimney requirements for your furnace installation and insure that it complies with local building codes and
ordinances.
WARNING: The furnace must connect to a code-approved masonry chimney with a flue
liner or an appropriately sized factory-built chimney that conforms to type HT (High
Temperature) requirements of UL 103 or CAN/ULC-S629 and complies with Chapter 11 of
NFPA 211, Standard for Chimneys, Fireplaces, Vents and Solid Fuel Burning Appliances.
The chimney and flue pipe must be clean and in good condition.
Chimney Size
The chimney flue is a vital part of your furnace installation. A properly built and maintained masonry
chimney or factory-built double or triple wall insulated flue will assure that the induction fan provides a
consistent draft under a variety of weather conditions.
Flue Diameter
The flue adapter that ships with the Frontier CX can be used with a 5” (127mm) or 6” (152mm) diameter
flue. A 6” flue will require use of a stove pipe reducer such as the 24 gauge 6” to 5” Imperial Stove Pipe
Reducer sold by Ace Hardware (Product UPC 0634672300069).
Chimney Height
The Frontier Series is a forced draft system which means the induction fan will control the draft through the
flue. Regardless, the flue must meet your local codes for height and provide for adequate draft. This
typically requires a minimum height of 12 feet (3.65 meters) from the base of the furnace.
Connecting to an Existing Chimney Flue
You may connect the Frontier Series to an existing flue or chimney subject to the following conditions:
1. A qualified professional has inspected, repaired (if necessary), thoroughly cleaned and determined
the chimney is suitable for use with a residential heating appliance that burns solid fuel.
2. Avoid using exterior chimneys (i.e., a chimney with one or more walls exposed to the outside below
the roofline). If it is necessary to use an
exterior chimney, the chimney flue size area must not
exceed two times the minimum flue area for the furnace. If an internal chimney is used, the
chimney flue size area must not exceed three times the minimum flue area for the furnace.

3. If your chimney flue exceeds the maximum area allowed, it must be lined with a suitable flue liner
that complies with the requirements of Chapter 11 of NFPA 211 3-1.2 -- Standards for Chimneys,
Fireplaces, Vents and Solid Fuel-Burning Appliances.
4. The minimum height of the chimney should be 12 feet (3.65 m) measured from the base of the
furnace.
5. Do not share a chimney flue with another furnace, appliance or fireplace. Do not use a flue that
already provides make-up air to the cellar or basement.
6. Tightly close and seal the cleanout opening in the base of the chimney.
