Things to Keep in Mind Before you Start

There are a couple of things to keep in mind when planning your venting run. The first is that each brand is designed and warrantied to only connect to components from within the same brand. It is not recommended to try to utilize components from different brands as this will cause an unsafe venting run and will void any and all manufacturer’s warranties. You will want to stick with the same brand of venting for the entire chimney system.

Also all chimney and stove pipe is sized and classified by the inside diameter of the pipe. For example, if your flue has a 6 inch inside diameter then you will want to choose a 6 inch Stove or Chimney Pipe. The first step in deciding what size venting you need is to check the product manual for your chosen appliance.

Class A Triple Wall and Double Wall Chimney Pipe Options that will work with a variety of Fireplace and Wood Stove Appliances

The top 3 Chimney Brands offered by Northline Express are DuraPlus, ShastaVent and Selkirk. Each brand offers all fuel, Class A Chimney pipe and each can be used on a variety of heating appliances. While all three brands are recognizable within the industry, there are a few differences between their product offerings as well as the benefits that each possess. 


DuraVent

DuraVent is the premier manufacturer of the venting industry. They have been a staple of the industry for over 50 years and they design their products with safety, innovation and function in mind. We offer two DuraVent lines, DuraPlus which is a triple wall chimney pipe and DuraTech which is a double wall chimney pipe. Both are Class A, all-fuel chimney systems, but there are a few differences between them.

DuraPlus

DuraVent Dura Plus logo

DuraPlus Chimney is a triple wall, all-fuel Class A chimney pipe that is designed to stay cool on the outside while providing a hot draft on the inside. 

The term triple wall refers to the three separate layers of piping. The three walls are constructed of a 430 stainless steel outer wall, an aluminized steel intermediate layer and an additional 430 stainless steel inner liner. In between the three pipe walls are two separate insulating layers. The first layer is a space that allows air to flow through to help cool the pipe, while the second features insulated layers of ceramic blanket that is held securely in position. In the unlikely event of a chimney fire the compressible blanket insulation permits the chimney liner to expand outwardly in a radial direction.

Designed for normal everyday use which can include continuous operation at 1000 degrees. It is also subjected to a series of rigorous high-temperature tests under UL 103HT. These tests include one hour at a maintained 1400 degree temperature within the flu as well as three 10 minute chimney fire tests at 2100 degrees Fahrenheit. 

DuraPlus makes installation a breeze with its precision twist-lock connections and minimal requirement of 2 inch clearance to combustibles. DuraPlus Chimney is designed for use with a wide range of appliances that are fueled by wood, gas, oil or coal including fireplaces, wood stoves, boilers, furnaces, ranges and more.

If you are looking for a great option to give you the best draft for your fireplace and wood stove chimney systems and a trusted name in the industry, DuraPlus Chimney is it.

DuraTech

DuraVent Dura Tech logo

DuraTech is a double wall, all-fuel, Class A chimney pipe system that offers the perfect balance of safety and performance. This “Solid Packed” Pipe is the most versatile chimney system on the market today. 

DuraTech’s double wall chimney system features an inner wall constructed of 430 stainless steel and outer wall options of 430 stainless steel or galvalume steel. Encased between the dual walls is a Thermal Tech ceramic, refractory blanket insulation. 

The inner wall is 25% thicker than competitive chimneys for an extra margin of safety. When you have your system burning at constant high temperatures, that extra 25% makes all the difference, because the system has been designed to operate at normal and continuous 1000 degree temperatures. DuraTech subjects their products to a series of rigorous high temperature tests under UL 103HT. These tests include one hour at a maintained 1400 degree temperature within the flu as well as three 10 minute chimney fire tests at 2100 degrees Fahrenheit. 

Made with a sleek 1 inch wall design provides easy installation that easily fits through 16” on center framing. They also feature lightweight insulation, twist-lock fittings, support boxes with factory installed starter sections, elbows with 360 degree swivel base and much more, 

A great option for Mobile Home Installations and to be used in factory built zero clearance fireplace installations. DuraTech chimney systems work with appliances that are fueled by wood, gas, oil and coal. This system can be used on appliances such as wood stoves, fireplaces, stoves, boilers, furnaces and more. 

DuraTech has installers in mind, as it is rated so you don’t have to install locking bands. It has a twist-lock connection, which most high temperature pipes have, but there are no locking bands or mechanical fasteners required. DuraTech has a huge selection of components to solve any challenge you may encounter. Some of the products they offer are: a snow splitter, a Reduced Clearance Square Ceiling Support Box, Adjustable pipe sections, 5 foot pipe lengths and more.

Featuring a minimum of 2 inch clearance to combustibles make DuraTech a great option for nearly any installation.

Constructed of 304 stainless steel on the inner and outer walls, ShastaVent is designed to provide better protection from corrosion damage.
