In Barrie Ontario in order to get insurance on a wood burning appliance you must have your appliance inspected by a WETT Certified Inspector. This will ensure that your fireplace, wood stove or pellet stove is properly installed and is not a danger to you and your family.

In Canada every chimney must be installed in accordance with B365-01 and the National Building Code or Provincial Building Code applicable to where you are installing appliance.

Venting shall be in accordance with Provincial Building Codes or National Building Code if none is available. Masonry chimney's must be built in accordance with building codes or a Factory Built Chimney may be used. Where certified for use with a specific chimney or class of venting system, the appliance shall only be used with that chimney or venting system.

A solid fuel appliance shall not be connected to a chimney that serves a natural gas or propane fired device. Only a solid fuel burning appliance certified for use in conjunction with oil-fired equipment shall be connected to a venting system serving an oil-fired appliance.

When a mechanical flue-gas exhauster is used, the chimney shall be capable of venting the flue gas produced when all the appliances not interlocked to prevent simultaneous firing are firing a their maximum rate at the same time and when the flue gas exhauster is operating.

A flue pipe shall be securely supported from the structure by means of metal or other noncombustible supports and horizontal pipes shall be supported at intervals not exceeding 3 m. the flue pipe shall be as short and straight as practical; and a single wall pipe shall not exceed 3 m total length of pipe and shall not have a total change in direction of more than 180 degrees.

The breech pipe must be securely fastened to the chimney and be made flush with the interior surface of the flue. It must also be properly sealed with the flue to prevent spillage of any flue gases.

Remember to check with your local building department if constructing a masonry chimney and fireplace. Inspection of the hearth, liner, damper and throat of fireplace must take place before enclosing with masonry or brick. A WETT inspection is only for your insurance company and will not always be accepted by the local Building Department.
