DuraTech Stainless Steel Chimney System
The main cause of chimney related fires is the clearance of the stainless steel chimney to combustibles. When installing a stainless steel chimney, be sure to follow all instructions and abide by all state and local codes.
DuraTech chimney installation instructions and parts.
Clearance is defined as the space allowed between two objects. When installing a DuraTech chimney you must always allow a minimum of 2 inch clearance between the chimney and any combustible materials. Combustible materials include but are not limited to: lumber, plywood, sheet rock, etc. Single wall stainless steel stove pipe or regular steel stove pipe must be a minimum of 18 inches away from combustible materials.
Stainless steel chimney pipe or DuraTech is a complete chimney system. It is tested to UL 103 HT for the United States and ULC S604 in Canada.
In the United States, stainless steel chimney DuraTech can be used with wood stoves, fireplaces, fire boxes, furnaces, boilers, water heaters, stoves, ranges, or other residential type appliances that are fueled by oil, gas, wood and coal that require a type A chimney.
In Canada, DuraTech can be used with oil and gas fired appliances listed for use with a Type A Chimney. DuraTech has not however been approved for use with solid fuel appliances in Canada.
DuraTech chimney comes in sizes ranging from 5 inch to 8 inch in diameter and 10 inches to 16 inches in diameter. DuraTech cannot be used with forced draft, positive pressure appliances. A maximum of 2 offsets of 30 degree from vertical can be used. This would amount to four elbows total.

Where Can I Get DuraTech Components
Always be sure to follow the appliance manufacturer's instructions to determine the chimney diameter needed for your appliance and the recommended clearances between combustible materials.
To figure the chimney's outside diameter you will need to add 2 inches to the inside diameter. Never use a chimney with an inside diameter that is smaller than the outlet on your appliance.
“Chimneys shall extend at least three feet above the highest point where it passes through the roof of a building, and at least two feet higher than any portion of a building within ten feet.” This is a statement, #211, that was released by the National Fire Protection Association Standard.
DuraTech may be installed up to 60 feet high, however, if the chimney extends above the roof more than 5 feet, an extended roof bracket must be used.
NOTE: Because of the overlap of joints, in order to calculate the chimney height once installed, you must subtract 1 ¼” from each section.
Placement of the chimney
Try to avoid making any modifications to roof beams and other structural components of your home when deciding what location is best for your chimney.
Recommended requirements for chimney enclosures.
All interior chimneys must be enclosed whenever they extend through closets, occupied spaces, storage areas, or any where the surface of the chimney can come in contact with people or combustible materials. You must be sure to maintain at least a 2 inch air space between the outer wall of the chimney and the enclosure.
When enclosing a chimney that is extended through multiple stories, local building codes for requirements in your area must be consulted. In the U.S. The National Fire Protection Association Standard #211 states: “Factory-build chimneys that pass through floors of buildings requiring the protection of vertical openings shall be enclosed with approved walls having a fire resistance rating of not less than one hour when such chimneys are located in a building less than 4 stories in height, and not less than 2 hours when such chimneys are located in a building more than 4 stories in height.”
In Canada, except in single family and two family dwellings, chimneys which extend through another story must have an enclosure with a fire resistance rating equal to or greater than that of the floor or roof assembly through which they pass.
Chimneys that are located in cold climates and are mounted on an outside wall should be enclosed in a chase. Exterior chases reduce condensation and creosote from forming. The chase will also enhance the chimneys draft. Be sure to include an access door by the Tee Cap for chimney cleaning access.
Stainless Steel Chimney Maintenance
Creosote is produced when wood is burned slowly. It produces tar and other organic vapors, which combines with expelled moisture. These creosote vapors condense in the slow burning fire chimney flue then accumulates on the flue lining. If ignited, it will create an extremely hot fire.
Stainless steel chimneys must be installed providing access for inspection and cleaning. During the heating season an inspection should be done monthly to monitor the creosote and soot build up. Spark arrestor screens should be checked every 2 to 4 weeks. To reduce the risk of a chimney fire, should creosote accumulate on the chimney cap, it should be cleaned or replaced. By doing this it will reduce the risk of a chimney fire.
Chimneys should be cleaned by a certified chimney sweep. However, if you have the ability to do it yourself, the proper tools will be needed. A plastic, wood or steel brush can be used but it is recommended not to use a brush that is harsh and will scratch the liner of your stainless steel chimney. The spark arrestor should be cleaned with a wire brush.
Where Can I Get Chimney Tools?
If burning coal the chimney should be cleaned thoroughly within 48 house of shutting down the stove for the season. By doing this it will reduce the corrosion in the chimney.
Chemical cleaners should be used only as a last result. Manufacturer's guidelines should be followed prior to using chemical cleaners. Using a chemical cleaner when it is not recommended may result in the warranty being voided.
If a chimney fire should occur, close all air inlets to the appliance and call 911. The chimney should not be used again until it has been inspected for damage by a certified chimney professional.
Painting the exterior metal parts of your stainless steel chimney is an option. However, the chimney cap should never be painted. If painting your chimney you must use a rust proof, high temperature paint. For the best result, all metal parts should be washed with a vinegar and water solution. By painting, you will increase the life of your chimney.
