Colinear pipe - This is a system with two separate pipes, one for combustion air and the other for exhaust.The space between the two pipes brings in fresh air from outside into the appliance for combustion. The inner pipe, separated from the outer pipe by spacers, vents and removes all combustion by-products and exhaust out of the appliance and out of the home. Coaxial pipe - Consisting of a pipe-within-a-pipe configuration, a coaxial system utilizes a smaller inner pipe that is fixed inside a larger outer pipe.There are two types of direct vent piping systems: Just remember, galvanized piping must be cleaned and prepped prior to painting to remove any residual machine oil or dust from the manufacturing process. If you must use galvanized pipe outside, we urge you to paint your pipe with a high temperature, rust-resistant paint. This is especially true in coastal areas. If the galvanized pipe is exposed, it is susceptible to eventual rust and corrosion. The need for stainless steel only arises when your pipe will be exposed to the elements. Having your chimney system exposed to the outdoors brings with it the risk of a 'cold hearth syndrome,' which can hinder drafting and produce more creosote.

It is highly recommended, if possible, to install your chimney in the interior of your home. When running Class A pipe within a masonry chimney, a chase, an attic, or any enclosure inside the home, it is economically wise to use galvanized pipe. Class A pipe is usually manufactured with either a stainless steel or galvanized (or galvalume) outer wall. When using Class A chimney pipe, it is important to plan or route the vent run wisely to minimize costs and maximize your savings. As the name implies, these pipes rely on the air circulating within them to keep the outer wall cooler and must also maintain a 1 or 2-inch clearance to combustibles. An example of this kind of Class A pipe is the IHP chimney pipe that is required for use with Superior and Astria manufactured fireplaces.

Air-cooled chimney - These pipes have larger inner diameters (usually ranging from 8 inches to 24 inches) with no insulation.

These pipes contain fiberglass or ceramic insulation to stay cooler on the outside and must maintain a 2-inch clearance to combustibles.

Solid-packed chimney - These pipes have smaller inner diameters (usually ranging from 5 inches to 8 inches) that have some insulation, either double-wall (like Simpson DuraVent DuraTech pipe) or triple wall (like Simpson DuraVent DuraPlus pipe).

There are two types of Class A chimney pipe: These adapters are very rare and are usually only offered by a manufacturer to link a very similar discontinued piping system to a currently offered system.

Building codes prohibit the use of any adapters not approved by the manufacturer. Unfortunately, if your existing make and model of pipe is a discontinued or obsolete brand, you will likely need to rebuild your chimney system from scratch. If you are looking to extend or redesign your current chimney system, you need to know the make and model of your existing Class A pipe and purchase the same type, if possible. The different brands of pipe are all distinctly engineered and must be used as a complete system from beginning to end. However, it is important to note that you should never mix-and-match different brands of Class A chimney pipe within one chimney system unless specifically allowed by the manufacturer. Class A chimney pipe is UL-listed, which permits its use with a range of different vent pipe manufactured by other fabricators and an even wider variety of fireplaces, stoves, inserts, and furnaces.
