Question 1
A free-standing stove may be connected to which of the following chimneys? Which two of the below are acceptable?
| Answer |
Responses |
| a) Any brand of chimney certified to ULC S629 |
92.31% |
| b) A code compliant masonry chimney |
84.62% |
| c) A UL High Temp wood-stove chimney |
6.59% |
| d) A certified, stainless steel wood-stove liner in an A Vent chimney |
7.69% |
|
|
Rationale
ULC S629, Standard for 650 °C Factory-built Chimneys covers the testing of chimneys made of stainless steel and materials other than metal. Some chimneys made of refractory (high temperature masonry) materials have been tested and listed as meeting the standard. These modular block chimneys are assembled in the field from shell and liner components with special insulation poured between them as the chimney is built. Modular block chimneys are rarely used, perhaps because they tend to be more costly than the other alternatives
Type A metal chimneys became popular in the 1950s as an alternative to masonry chimneys. Most are constructed of a stainless steel inner liner, a layer of insulation and a shell of galvanized steel, aluminium or stainless steel. These chimneys are tested to ULC Standard S604, which assumes a continuous flue gas inlet temperature of 540 °C (1,000 °F). Type A chimneys are considered suitable only for oil- and gas-fired appliances. These chimneys were used for wood-fired systems until failures due to creosote fires began to appear in the late 1970s. The inner liner of the chimney could buckle with the intense heat of a severe chimney fire. An existing Type A chimney should be upgraded to a new 650 °C chimney if a new appliance is being installed. Corrosion, especially through galvanic action, was also a major issue.

Question 2
Requirements for the construction of masonry fireplaces are found in:
| Answer |
Responses |
| a) Fire Code |
0% |
| b) Building Code |
65.22% |
| c) CSA B365 |
1.09% |
| d) All of the above |
33.70% |
|
|
Rationale
WETT Reference Manual, chapter 4, section 4.1
The requirements for the design and construction of masonry chimneys are provided by a series of prescriptive clauses in building codes. Requirements in provincial building codes are usually similar or identical to those in the NBC.
Prescriptive requirements give the details of design and construction, unlike the performance requirements for factory-built chimneys, which are found in safety test standards.
|
|
Question 3
The height of flue tiles protruding from the top of a chimney must . . .
| Answer |
Responses |
| a) protrude at least 4” (100 mm) and not more than 6” (150 mm) |
36.96% |
| b) It does not matter as long as the tile is a minimum of 2” above the crown. |
7.61% |
| c) protrude at least 2" (50 mm) and not more than 4" (100 mm) |
52.17% |
| d) protrude less than 12" |
3.26% |
|
|
Rationale
WETT Reference Manual, chapter 4, section 4.2
NBC 9.21.3.10 Extension of Chimney Liners
Chimney liners shall extend from a point not less than 200 mm below the lowest flue pipe connection to a point not less than 50 mm or more than 100 mm above the chimney cap.

Question 4
A WETT-certified inspector should condemn any installation that is not code compliant.
| Answer |
Responses |
| a) True |
25% |
| b) False |
75% |
| |
|
|
|
Rationale
WETT-certified inspectors have no authority to reject or condemn an installation: they are not the Authority Having Jurisdiction and cannot command a Stop Usage. They are only there to report on what they SEE at the time of inspection and whether or not the installation is code compliant. They may, however, recommend a replacement, removal or repair. If there are significant compliance issues with a system, the report itself speaks volumes, since it is commonly understood that codes are designed with the minimum requirements of what are considered non-hazardous. It should be suggested in writing that the system should not be used until it meets code compliance.

Question 5
During a level-1 inspection, in the case of a conflict between the requirements of the building code and those of a referenced document — such as manufacturer’s certified instructions — the requirements of the building code shall govern.
| Answer |
Responses |
| a) True |
28.26% |
| b) False |
71.74% |
| |
|
|
|
Rationale
WETT Reference Manual, chapter 1, section 3.8
NBC 9.33.5.2
Because the building code is the primary document and is usually adopted into provincial housing legislation, its requirements can, in certain circumstances, supersede those of a standard that is referenced in the code. If there were a conflict between a clause in the building code and a requirement in an installation code — such as CSA B365 — that is referenced in the building code, the building code requirement would be the one to use.
This is confirmed in section 2.7 Referenced Documents of the building code. Sentence 2.7.2.1. states that “In the case of a conflict between the provisions of this Code and those of a referenced document, the provisions of this Code shall govern.”
