Look Inside the Book

Every page has one big drawing and a box with the numbers and steps you need to know:

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

You're looking at a nozzle stamped 0.75 GPH, and the pump on this burner is set to 140 psi. The question sounds simple: how much oil is it really firing?

The manual has the answer in the middle of a paragraph about pressure, flow and square roots. You read it at night after work, and by morning it's gone.

0.75 GPH at 100 psi → about 0.89 GPH at 140 psi (square-root rule)

In this book, that same nozzle is a drawing: 0.75 GPH at 100 psi on one side, about 0.89 GPH at 140 psi on the other, and the square-root rule in a box between them. One look and you see why more pressure means more oil.

Pump pressure and the cutoff test, electrode gap, the cad cell readings, overfire draft and the smoke spot each get their own page too.

You work out the firing rate yourself and set up the burner without going back to the manual.

COMPARE FOR YOURSELF

Same Topic, Two Ways to Study It

THIS
  • The manual: line after line of text
  • Burner parts explained only in words
  • You walk into the exam still unsure
The high-pressure gun-type burner consists of an electric motor which, by means of a flexible coupling, drives both the fuel unit and the blower wheel mounted on a common shaft. The fuel unit draws oil from the supply line through a strainer and delivers it at regulated pressure to the nozzle assembly located within the air tube, where atomization occurs. Combustion air supplied by the blower is regulated by the air band and shutter, while ignition is provided by electrodes energized by a transformer or igniter under supervision of the primary control.
FOR THIS
  • The whole gun-type burner in one drawing
  • Each part's job in a box
  • You see it and you get it
Motor runs, no flame: a split coupling stops the pump while the fan keeps turning.

One Page, One Topic, All Clear

Think of it this way:

It's a cold morning, the burner has locked out and the homeowner is standing right behind you. You need the cad cell reading, and you need to know what it means.

In the book you open the cad cell page and it's all drawn: over 20,000 ohms in the dark, 300 to 1,000 ohms with flame, and the 1,600-ohm line you never go above.

Firebrick or ceramic fiber; oil-soaked or cracked after a puff-back means replace.

Same with one-pipe vs two-pipe, the hot-water boiler loop, firing rate at other pressures and the no-heat method in 8 steps: each one on its own page.

Oil Burner Technician Illustrated is 9 parts and 66 topics, all drawn, and it closes with the numbers to know by heart, how exam questions are worded and a night-before review map.

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

Frequently Asked Questions

Is it for me if I already work on oil burners and just need the license?

Yes. It doesn't treat you like a beginner: it takes the work you already do and puts it in order, tank to chimney, with the numbers and the troubleshooting steps the exam asks about.

Does it work for my state's license exam?

Oil burner licenses are issued by each state (and in some places by the city), and each exam has its own rules. The book covers what they share, built on NFPA 31, the NORA technician curriculum and manufacturer specs, with Massachusetts 527 CMR 4.00, Maine Fuel Board and Connecticut DCP rules as examples. Always check values against the current official version for your state and the equipment manual.

Is this official material?

No. It's an independent illustrated study book. It isn't published or endorsed by NFPA, NORA or any state board.

Does it replace a course or training?

No. It's a study and review book to use alongside your training, your field hours and your state's requirements. It doesn't give you a certificate, a license or CEU credit.

Are the practice questions the real exam questions?

No. They're written for this book in exam style, so you can find your weak spots. They aren't official questions from any exam.

When and how do I get it?

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

Do I have to pay every month?

No. It's a one-time payment. No subscription.

Can I have it on paper?

Yes. It's a PDF you can print at home or at a print shop and keep 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 and retaining nothing.
