What’s inside your chimney?

How well do you know the chimney parts that keep you safe and warm?

The smoke and waste from your stove are expelled through your chimney’s flue system.  A flue system is a duct, pipe, or opening in a chimney for conveying exhaust gases outdoors.  We recommend your chimney has a stainless steel liner to prolong the life of your chimney and stove.

It’s important that your chimney adequately expels this waste, if waste and smoke build up it can damage your fireplace and leak poisonous gas back into your home.  To prevent build ups and find issues early, we recommend your stove is cleaned twice a year.

If an issue does arise, it’s helpful to know the parts of your chimney.  This is why we have created this guide.

1.  Cowl
A cowl is a covering used to create a good updraft of a chimney to ensure easier lighting and prevent backflow.  A cowl also prevents birds and rain from entering your chimney.

2.  Chimney Pot
The chimney pot is a pipe that narrows at the aperture and increases the up draught.

3.  Chimney Stack
The chimney stack is the part of the chimney that projects above the roof.

4.  Roof

5.  Flue
The flue is a duct for smoke and waste gases produced by fuel burn

6.  Flexible Flue Liner
Flexible flue liner is a metal hose like structure that lines the inside of a flue.  This makes the appliance more efficient and cost effective than a clay chimney liner.

7.  Throat Plate
The throat plate restricts airflow for optimal performance and prevents debris from falling into your stove.

8.  Lintel
The lintel is a horizontal support of timber, stone, concrete or steel.

9.  Vitreous Enamel Flue Pipe
The vitreous enamel flue pipe connects your stove to the flue liner.  It has an enamel coating applied to ensure durability.

Over the next couple of weeks, we will be sharing common chimney issues and how to solve them.  Knowing the parts of your stove can help you to diagnose your chimney problem.
