Orillia WETT Certified Inspector

The Orillia WETT Inspection service provides Certified WETT inspections on Wood stoves, Pellet Stoves and Fireplaces.

Do you require a basic visual inspection such as for insurance or pre-purchase inspection of a home equipped with a wood burning appliance or fireplace? A basic visual inspection is a general overview of the readily accessible parts to determine if the system meets current regulations. Most often homeowners ask about WETT (Wood Energy Technical Transfer) because their insurance company has asked that they have their appliance WETT certified

Typically, when people are looking for an insurance type of inspection, a visual inspection is conducted to determine if there is evidence of any problems with the installation. This includes examining clearances, chimney heights and visual signs of deterioration. If there are concerns identified, then the inspector should make a recommendation that the appliance be checked and, if necessary, repaired by a WETT certified technician

Woodstoves and fireplace inserts are required to be installed according to CSA B 365 Installation Code for Solid Fuel Burning Appliances and Equipment. Masonry fireplaces are required to be built to the Ontario Building Code.  Most insurance companies, for home insurance purposes, require a report stating that the wood burning appliance meets these installation practices

Types of Chimneys:

Conventional Masonry  chimneys have been popular for many years. Most masonry chimneys built since the 1950’s are lined with flue liners of clay or other materials, which improve the durability and performance of the chimney. The clay  tiles must be in good condition and joints sealed with high temperature cement in order to be used for fireplaces. If you have an older unlined masonry chimney and want to use it to vent a wood burning hearth mount insert, it must be lined with approved metal liner, chimney liner and appliance flue collar must be the same size to ensure proper draft.
Type A metal chimneys became popular in the 1950’s. They were designed primarily for use with oil furnaces, but ended up being used for wood burning appliances as well. Type A chimneys cannot withstand severe chimney fires without damage. They are not suitable chimneys for wood burning appliances. Since 1983, chimneys specifically designed for use with wood-fired appliances have been required.  If an A type chimney was installed in the original configuration it would be considered “Grandfather Protected” as long as no modifications have been made.

650ºC Metal Chimneys In 1981, a new standard for factory-built chimneys was published. This standard requires factory built chimneys to be tested at a continuous flue gas temperature of 650°C (1200°F). By 1983, this standard had been incorporated into most building codes. A modified version of the 650°C standard is used to test chimneys for factory-built fireplaces.

The top of a chimney must be at least 900 mm (3 ft.) above the point where it contacts the roof. It must also be 600 mm (2 ft.) above any roof surface or structure within a horizontal distance of 3 m (10 ft.). Metal chimneys need a cap to keep water out of the space between the inner liner and the outer shell.

All chimneys must be installed in accordance with the manufactures installation instructions.  Do not mix parts from different manufactures unless it is stated that this is acceptable.  If in doubt contact the manufacturer or their local representative.
