Your chimney has a big responsibility. Chimney safety can be promoted by making sure your chimney is operating correctly. It carries toxic gas out of your home and while doing its job it must withstand constant attacks by acid, creosote and extreme temperatures for months on end. These conditions cause chimney damage and deterioration. When that happens your family's safety is in question. The risks of carbon monoxide poisoning and/or a house fire becomes very real. The Furnace Flue
Chimneys operate on the principle that hot air rises because it is less dense than cold air. When a chimney is filled with hot gas, the gas tends to rise because it is less dense than the air outside the house. The rising hot gas creates a pressure difference called draft which draws combustion air into the appliance and expels the exhaust gas outside. The hotter the gas as compared to the air outside determines the strength of the draft. The fireplace flue
The chimney's function is to produce the draft that draws combustion air into the appliance and safely exhausts the gases from combustion to the outside. To fulfill this role, the chimney needs to conserve flue gas heat to produce strong draft, be resistant to corrosion on the inside and to weather effects from the outside. It needs to be sealed to prevent leakage, tolerate the high flue gas temperatures that can result from chimney fires, and must isolate nearby combustible materials from flue gas heat.

How often should I clean my chimney?
A clean and regularly inspected chimney is a safe chimney. Although there is no “code” as to how often a chimney is to be cleaned, industry standards recommend cleaning your chimney when there is an 1/8” to 1/4” of creosote buildup, however, cleaning your chimney at the beginning of the heating season should become routine. Depending on the use of the chimney, cleanings may also be required during the heating season.How to clean your chimney
What if my chimney vents a furnace?
What causes creosote build-up?
The main cause of creosote is burning unseasoned wood. Another cause is not burning the fire hot enough. Slow, smoldering fires do not allow the flue gases to burn off before cooling down and bonding to the inside of your chimney. The type of chimney you have, the state of the chimney interior and draft of the chimney all contribute to possible creosote buildup.Learn how to build a fire successfully
What happens if creosote builds up?
Can you say chimney fire? Chimney safety can be jeopardized in this situation. Creosote is very flammable and ignites easily. When creosote ignites in your chimney it will sound as if a jet has done a flyby above your home. It is a terrifying sound as flames shoot out the top of your chimney like a rocket. Flames and sparks can also ignite your roof. Many house fires are caused from an unsafe, creosote filled chimney.
How do I know if my chimney is safe?
With yearly cleanings an inspection should be done. An evaluation of the chimney and the flue should be made and it should be checked for any obstructions. An inspection will be more accurate if the chimney is swept prior to performing the inspection.
I don't burn wood, should I still get my chimney cleaned every year?
All heating appliances rely on proper venting in order to burn efficiently. This venting is provided by your chimney. If your chimney is not free of obstructions, the proper draft will not be obtained. Oil furnaces, gas appliances, boilers and hot water heaters all rely on proper venting.
What if the inspection shows my chimney is not safe?
There are several ways to rectify chimney deterioration. Stainless steel relining is a solution for many chimney problems. Stainless steel relining is cost efficient and can be done in just a few hours by the regular do-it-yourselfer.
