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, and sheet rock. 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 inches to 8 inches in diameter and 10 inches to 16 inches in diameter. DuraTech cannot be used with forced draft, positive-pressure appliances. A maximum of two offsets of 30 degrees from vertical can be used. This would amount to four elbows total.
