CAZ & Combustion Analysis

Pressure imbalances inside a home don't just affect energy performance — they affect whether combustion appliances draft safely.

This two-day course gives you the hands-on skills to test for combustion safety risks, interpret what you find, and recommend solutions grounded in building science.

WHY TAKE CAZ & COMBUSTION ANALYST TRAINING

Benefits of CAZ & Combustion Analysis Certification

Combustion safety is one of the highest-stakes assessments a weatherization professional performs. This course builds the knowledge and hands-on skills to get it right — from setting up worst-case conditions to interpreting what the readings actually mean.

Protect Occupants from Combustion Hazards

Learn to identify the conditions that cause backdrafting, spillage, and sustained draft failure and understand how everyday factors like duct leakage, exhaust fans, and door restrictions.

Test with Confidence Under Worst-Case Conditions

Go beyond the basics. You'll set up manometers, define CAZ boundaries, establish worst-case depressurization, and conduct draft and combustion analysis.

Connect Combustion Safety to the Whole House

Understand how moisture, air pressure, and combustion dynamics interact. You'll be diagnosing compounded building issues and developing mitigation strategies that address the system, not just the appliance.

"The House of Pressure demonstration was one of the most useful things I've seen in a training. It made abstract pressure concepts real in a way that I could immediately explain to my crew. I've been doing this work for eight years and I still learned something I didn't know."

- Michael Kelly

HOW IT WORKS

How to Complete the CAZ & Combustion Analysis Course

You can get the CAZ & Combustion Analysis Certification in just three steps!

1. Take Our Course

Day 1 covers the foundations of CAZ testing — pressure dynamics, manometer setup, worst-case depressurization, appliance types, and combustion analysis fundamentals — anchored by a live House of Pressure demonstration.

2. Apply Learned Skills

Conduct a full CAZ procedure on a single appliance, then advancing to multi-appliance scenarios, shared venting, and compounded building science issues. You'll troubleshoot complex field conditions and develop integrated mitigation strategies.

3. Earn Your Certificate

Complete the knowledge check and course assessment. Finish the course and receive your Everblue Certificate of Completion.
