These are real pages from the book. The table of contents is the full one: 8 parts and 62 topics.

The Problem Isn't You. It's How It Was Explained to You.

You're standing at the base of an old brick chimney with the insurer's form on a clipboard. The form asks about the liner, the walls and the cleanout, and the homeowner is right behind you.

The manual covers it in paragraphs: flue liners, masonry thickness, cleanout openings, crown, all in one long run of text. You can't picture where one part ends and the next begins.

Flue area: never less than the flue pipe; fireplace flues from NBC Tables 9.21.2.5.A and B.

In the book, that chimney is one page: a cut-away drawing from the cleanout at the base to the crown at the top, every part labelled, with at least 75 mm of solid masonry drawn around the flue.

The same goes for clay liners and their joints, the 50 mm and 12 mm clearance to framing, the 3-2-10 height rule, the crown, cap and spark arrestor. Each one has its own page.

You recognize each part on site, tick the box and move on. No going back to the manual in the basement.

  • The manual: line after line

  • You get to the exam or the job with doubts
Chimney connectors shall be constructed of materials suitable for the flue gas temperatures produced by the appliance served. Except where otherwise provided, single-wall connectors shall be installed so as to maintain a clearance of not less than 450 mm from combustible material, which clearance may be reduced only by means of a shield conforming to the applicable provisions. Listed double-wall connectors, tested to the relevant standard, may be installed at the reduced clearances stated on the certification label and in the manufacturer's installation instructions, provided all conditions of the listing are met.

One Page, One Topic, All Clear

Think of it this way:

It's the night before your wood heat exam. One practice question shows single-wall pipe running close to a panelled wall: does it pass?

You open the book at the flue pipe page and see single-wall and double-wall pipe drawn side by side: 450 mm to combustibles for single-wall, the label clearance for listed double-wall.

Camera up the flue, inspector in the attic: liner joints, firestops, 50 mm to framing

The same with floor protection (450 mm in front, 200 mm around), shield reductions, the 3-2-10 chimney rule, the 3 mm sweeping guideline and the Level 1 route: each one on its own page.

Chimney & Wood Heat Illustrated is 8 parts and 62 topics, all drawn, and it ends with a review: every number on one page, the common mix-ups and a checklist before you sign.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been sweeping or installing for years?

Yes. It isn't a beginner's book: it puts the rules you already apply in order, one topic per page, so you can review them before the course or check one on the job.

Where does the content come from?

From CSA B365 and the National Building Code of Canada (Sections 9.21 and 9.22), plus the ULC standards for listed equipment, all in metric. It's written for Canada and isn't based on NFPA 211, the US standard. Codes are adopted province by province (Ontario, for example, has its own Building Code), so always check the code in force where you work and the appliance manufacturer's instructions.

Is it official material?

No. It's independent study material, not affiliated with or endorsed by WETT Inc., CSA Group, NRC, any provincial authority or any school.

Does it replace the course?

No. It's a book to study and review alongside your course and field training. It doesn't give you a certificate and doesn't count toward one: certification comes only from the accredited course and its exam.

Are the practice questions the ones on the exam?

No. The exam-style questions are written for this book. They aren't official questions from any exam.

When and how do I get it?

The book and the 2 bonus books come as a PDF by email, to the address you enter at checkout.

Do I have to pay every month?

No. It's a one-time payment.

Can I have it on paper?

Yes. The PDF is printable: print the whole book or just the pages you want in the truck.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

Before You Close This Page

No more rereading the code with nothing sticking.

The single-wall pipe clearance: you see it drawn, and that's it.

You get to the exam or the job knowing where everything is.
