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

You're on a service call with a U-tube manometer on the manifold tap. The water moves, and you're not sure if you read one column or both.

You've gone through it in the manual. But it's paragraphs of fine print, and the one line that matters is buried in the middle.

U-tube: add both column moves (1.75 + 1.75 = 3.5 in. w.c.) · Digital: zero before connecting

In the book, the manometer is a drawing: the U-tube with both columns marked, 1.75 down and 1.75 up, for 3.5 in. w.c. Next to it, the digital one with a single reminder: zero it before you connect.

The gas train, draft and spillage, combustion air, the combination gas valve and the framing drawing work the same way: each one on its own page.

You get it, and you take the reading without going back to the manual.

COMPARE FOR YOURSELF

The Same Topic, Two Ways to Study It

THIS
  • The manual: line after line of fine print
  • The gas train explained only with words
  • You walk into the exam unsure
The gas supply to the appliance shall commence at the point of delivery, downstream of the meter, and continue through the piping system, which shall be sized in accordance with the applicable tables. An accessible manual shutoff valve shall be installed upstream of the appliance connector, and a sediment trap shall be provided as close to the appliance inlet as practicable. Gas then passes through the listed connector to the combination control valve, the orifice and, finally, the main burner assembly.
FOR THIS
  • The gas train in one drawing
  • Every part in order, in a box
  • You see it and you get it
Meter → piping → shutoff → trap → connector → valve → orifice → burner, in one drawing.

One Page, One Topic, All Clear

Think of it this way:

It's a no-heat call in January. The pilot holds, the wall switch clicks, and the burner stays off. The customer is standing right behind you.

You open the book to the millivolt page and measure in order: thermopile, wall switch, TH/TP terminals. Then the combination gas valve, each part drawn with the symptom it gives when it fails.

14 × 16 × 8 ft = 1,792 cu ft: enough indoor air for about 35,800 Btu/h.

Same with the manometer, direct vent terminations, combustion air, the thermopile and the annual service: each one on its own page.

Gas Hearth Specialist Illustrated is 8 parts and 64 topics, all drawn, and at the end you get all the numbers on one page, the most frequent field mistakes and a review plan for the exam.

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

Frequently Asked Questions

Is it for me if I've been installing for years and haven't studied in decades?

Yes. It isn't written for beginners: it puts what you already do in order, one drawn page per topic, so you can review fast.

Where does the content come from?

From the current NFPA 54 / ANSI Z223.1 and the IFGC, NFPA 211, the ANSI Z21 appliance standards and manufacturers' listed instructions. Every code value comes with its source. States and cities adopt these codes with their own amendments, so your local code and AHJ have the final word.

Is it official material?

No. It's independent study material, not issued or endorsed by any code body or certification organization. It doesn't give you a certificate or continuing education credits: the certification comes only from the certifying body, after its own exam.

Does it replace a course or formal training?

No. It helps you study and review. On the job, the manufacturer's manual and your local code and AHJ always come first.

Are the practice questions the ones on the exam?

No. They're written for this book in exam style, with explained answers, so you know what to review.

When and how do I get it?

The book and the 2 free books arrive as PDFs by email, at 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?
