The practical reference for choosing, installing, and troubleshooting vents and flues. No marketing—just what works and why.
About this book
Vents and flues don't fail quietly. A blocked flue means combustion products in your home. A wrongly sized vent causes draft problems, condensation, and equipment shutdown. A misrouted exhaust line can ice over in winter or allow pests in summer.
Yet most technicians and homeowners rely on guesswork, outdated rules of thumb, or manufacturer instruction sheets written for lawyers, not practitioners. This handbook cuts through that noise. It explains what vents and flues actually do—how they carry away combustion byproducts and moisture, what forces control draft, and why diameter, slope, insulation, and termination location all matter together. You'll learn how to size a vent correctly, diagnose why a system won't draft, specify the right materials for your climate, and identify the difference between code-compliant and code-violating installations you see in the field.
Written for HVAC professionals, facilities managers, contractors, and serious hobbyists who want concrete knowledge, not marketing.
Reader Reviews

★★★★★I've been doing HVAC work for 18 years and I found real value here, especially the sections on draft calculation and why condensation happens in certain climates. The chapter on choosing the right vent for your specific situation is solid—concrete examples I can actually use on job sites. My one complaint: the troubleshooting section could have gone deeper on diagnosing slow draft vs. blockages, but that's a minor gap in an otherwise practical reference.
