Installing a chimney

You have assembled your wood stove and are now ready to install your chimney. The chimney serves to draw the combustion air from the wood burning heater and expel the flue gases to the outside. Therefore, it is crucial that it is properly installed with respect to the manufacturer’s instructions, as well as current municipal regulations.

This article outlines the installation of a 650°C factory-built chimney. Before starting, find out if a permit is required to do this type of work in your municipality.

There are two main types of chimney on the market : metal factory-built chimneys and masonry chimneys. The 650°C factory-built chimney can withstand the elevated temperatures produced by a chimney fire. It « insulates » the combustible materials which are found near the high temperature gases circulating in the flue. Most of these chimneys have 5 cm (2’’) of insulation between the inner lining and the outer shell.

Masonry chimneys are generally made of stone or brick with a clay liner. They may contain a stainless steel liner to prevent damage caused by a chimney fire. Their installation is very complex. If you wish to install this type of chimney, it is strongly advised to consult with a qualified mason who is familiar with the requirements of the building code.

Determine the location of the chimney

Note : The ceiling support used in the basement to allow the chimney to pass to the main floor should be firmly attached to the floor joists.

0.1 

Using a plumb line, line up the centre of the flue collar on the wood stove. With a pencil, mark the point on the ceiling which corresponds to the end of the plumb line.

0.2 

Place the ceiling support against the ceiling, centred on the mark made using the plumb line. Trace the outline of the support’s opening onto the ceiling.
