WETT Inspection Barrie – Report Issued at Inspection


WETT Inspection Barrie – with the price of electricity going through the roof, more and more people are turning to wood burning systems to heat their homes. While cheaper than either electricity or oil, it also poses a greater risk of fire. If you currently heat your home (completely or partially) with wood, it is in your best interest to have your system inspected by a Wood Energy Technical Transfer (WETT) specialist.


In fact, most insurance companies today require a WETT certification to honor your policy.
Q. How do I get a WETT inspection or WETT certificate?


A: There is no such thing as a WETT inspection, nor can any appliance be “WETT” certified. What is issued is an inspection report by someone who is a WETT certified technician.  There are 3 levels of inspection.  Level 1 ( Site Basic ) is typically for insurance company requirements.


I frequently get requests for a “WETT Certificate,” a “WETT Certification,” a “WETT Approval” or they ask if it’s a “WETT Certified installation.” I WETT Inspection Barriealso get requests if my company is “WETT Certified.” All of which are incorrect. As a WETT Certified Technician I will inspect your wood burning appliance and issue with an Inspection Report based on the type of WETT Inspection you require.


There are no legal requirements in Canada for a person to be WETT certified in order to perform inspections. However, many insurance companies are insisting that the inspection and/or installation and/or maintenance of wood-burning appliances and equipment be performed by someone who is WETT certified. The installation and maintenance of wood burning appliances is not regulated in Canada. WETT certification implies that the inspector has met the educational and experience requirements required by Wood Energy Technology Transfer Inc.  a non-profit training organization.


WETT Inspector Certification


Wood Energy Technology Transfer (WETT) requires an individual to take 3 courses and obtain a passing grade of at least 70% in each.


CODE COMPLIANCE: consists of:


Regulatory Structure and Function –  Use of documents such as Ontario Building Code, Fire Code, Municipal Bylaws, and Product Safety Standards.  Identify which agencies Test and Certify wood burning equipment.


Inspect Installation of Free Standing Wood Stove – Review Certification Standard,  Compare Manufactures Certified Installation instructions and meets Clearance Requirements of CSA B365-10 and Table 3 or NBC 2005


Inspection Issues – Check Clearances, floor protection and venting arrangement.Masonry Fireplaces are typically difficult to inspect


Masonry Fireplaces –  Typically built by masons who utilize traditional designs.  Requirements for masonry fireplaces are found in NBC 9.22


Difficulty of Inspection – as can be seen in picture to the left,  fireplace construction is difficult to inspect and often defects in construction are not visible.  Most masonry fireplaces are inspected during construction by building department inspectors who are responsible to ensure proper construction methods are used.




This WETT Certification course starts out with case studies involving potential situations you could encounter as a Certified WETT Inspection provider regarding type and placement of wood heating appliance.  Clearances and clearance reduction in accordance with B365-01 are discussed. Sample space heater inspection forms are filled out using sample information. Chimney height requirements for different locations are discussed to ensure adequate draft for unit.  Flue installation and thimble installation are also covered.  There are many more items regarding different type of installs and also included is requirements for flue collars and flue pipes.




Site Basic Inspection – Level 1 is described a ( Readily Accessible )  “Readily Accessible” means quickly or easily reached for inspection.  A Level 1 inspection does not require the use of special tools for opening or removal of any panel, door or other covering; not does it require the use of ladders.  It does not require the disassembly of system components.  A tape measure, light, mirror, camera, magnifying glass and binoculars comprise the usual tools required to perform this inspection.

WETT Inspection Barrie – Creosote


Creosote is the by-product of incomplete combustion of any fossil fuel such as wood, oil, or coal. When the build up is more than 1/8th of an inch thick it should be removed to avoid possibility of a fire within the chimney. There are three different forms of creosote: granular deposit, brittle puffy, and third degree hard slag. The form of creosote in any system is dependent upon appliance efficiency, ambient temperature of chimney liner, improper operating techniques, and condensation…or a combination of all four.


When creosote reaches the brittle or third degree form the possibility of it igniting becomes very high; upon ignition it can cause very severe damage to the chimney and any surrounding structure since it could burn in excess of 3000 degrees. How hot is 3000 degrees? It’s hot enough to make the flue pipe look like a stove element!


Some chimney fires have been described as sounding like a jet plane or train going through the house. The purpose of a chimney is to effectively exhaust smoke and its by-products out of the living quarters not contain a fire and the extreme temperatures it produces!  Creosote is not your friend!
Q: How long is a WETT inspection report valid for?


A: The nature of any inspection report is that it records what was seen at the time of the inspection. After completing an inspection report and leaving the premises, the inspector has no control over, nor knowledge of, any changes that may take place on a wood-burning appliance installation.  Consequently, an inspection report can only warrant what was seen and recorded at the time of the inspection.


Q: How much does a WETT inspection cost?


A: The cost of the WETT inspection has a few factors, namely how many appliances are being inspected and whether the inspection is part of a home inspection or as a standalone inspection. Regular fee for WETT Inspection is $175.00 or if part of home inspection only $50.00


Q: How long does a WETT inspection take?


A: Most WETT inspections can be done within an hour with written report given to you at the end of the inspection.

 WETT Inspection – History of Wood


Wood heat was not only the main source of heat for our fore fathers, wood fires also were used for cooking, heating water for clothes washing, baths and all the essentials of life. To accomplish these task there was normally an open fireplace. I am sure most of you have seen pictures of the pioneer housewife with the pot of food dangling on a hook inside the open fireplace.


A wood burning stove consists of a sealed combustion chamber (in which the wood is burned) connected via a stovepipe to a flue that vents smoke and other combustion products to the outside. It is the fact of being sealed that is one of the main distinguishing features of wood burning stoves. They are popularly believed to have their origins in the Franklin Stove though this itself was derived from earlier designs, and ironically initially employed an open, rather than sealed, design.


EPA “Environment protection agency” was the catalyst that dictated the newer generation high technology stove. The EPA mandated that all new stoves must emit only very minimal pollutants to the environment. To overcome the health hazard from the pollutants from the smoke, EPA set particle emission standards to which the stove had to meet, similar to the automobile industry, that the manufacturers had to meet in order to legally sell their wood stoves.


The next generation of Wood Stoves and Wood Inserts became popular as many homes had open fireplaces that were very attractive but very inefficient. These Wood Stoves and Inserts had a fairly good controllable airflow, usually with some sort of restrictive baffling system, allowing approximately 30% efficiency from the wood fuel. For many years these stoves heated the homes and were considered to be a wonderful heat source. Today, these types of stoves are illegal to sell in most states, due to the high particle emissions emitted from the exhaust chimney. As our population has increase, it has become necessary to reduce the particles being emitted from the stoves in the form of smoke. Studies have confirmed that the particles from the stove smoke are not only a nuisance, but also cancerous as the particles will lodge in the lungs of people.


Biomass fuel is essentially any type of renewable biological material that has good combustion. It obviously has the desirable characteristic that being renewable implies a life cycle, and hence a period of growth which typically ensures it is self-balancing as regards carbon output. The most commonly used biofuels are of course logs, wood pellets and other forms of reclaimed wood, but you can even burn husks from cereal crops and nuts (so long as your particular burner is capable of accepting it).


Not everyone is able to take advantage of a wood burning stove though. Common impediments are an unsuitable property, air pollution regulations, lack of access to or storage space for fuel (principally seasoned wood or specially manufactured pellets). And anyway, there isn’t at present the capacity or infrastructure to support everyone converting to wood burners.


When buying or installing a wood burning appliance in your home, you should have unit inspected by a WETT Certified Inspector. Most insurance companies will require an inspection report from a WETT Certified Inspector prior to issuing a home insurance policy.


Installation Requirements for Wett inspection


Wood Energy Technology Transfer Inc. (WETT Inc.) is a non-profit training and education association managed by a volunteer Board of Directors elected by holders of valid WETT certificates. Through its administrative designate, WETT Inc. functions as the national registrar of the WETT program. Through professional training and public education, WETT Inc. promotes the safe and effective use of wood burning systems in Canada.


The WETT system consists of several courses recognizing the various types of work done by wood energy professionals. Certification is achieved by completing courses to earn educational credits. A technical reference manual has been prepared to assist trainees in preparing for courses and as a reference manual for certificate holders.


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.


Every wood stove installation requires a sound masonry chimney (more on these later) or a UL approved Stainless Steel Class “A” Insulated Chimney. The WETT inspector will identify and ensure the proper chimney or flue pipe is being used.


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.


A solid fuel burning appliance shall not be connected to a chimney that is connected to a fireplace or incinerator, except where; (a) the fireplace or incinerator is made inoperable; (b) all entries to the chimney flue, other than the appliance flue pipe, are effectively sealed with noncombustible materials; (c) access for cleaning is provided; and (d) the fireplace damper handle is made inoperable.


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.


When a flue pipe is passing through a thimble, the female end of the flue pipe shall reach but not protrude beyond the interior surface of the flue. The male end of the flue pipe shall extend beyond the thimble by at least 30 mm. A flue pipe or manifold serving one or more solid-fuel-burning appliances shall be constructed of steel or other approved noncombustible material with melting point of not less than 1100 degrees Celsius. Galvanized steel shall not be used.

 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. Although WETT Certified Inspections were once only required by Insurance Companies, many times Realtor’s or Municipal Building Inspectors will now require one.
