🔥 HVAC TECHS — ARE YOU TESTING YOUR BOILER DRAFT CORRECTLY? 🔥
🔧 Today we're breaking down combustion analysis and chimney draft testing on a Buderus G124X natural gas boiler!
Ever wonder why your O₂, CO₂, CO, and draft readings change depending on where you place your analyzer probe? 👀
🌡️ Here's what we're covering:
✅ Proper combustion analyzer placement
✅ Understanding O₂, CO₂, and carbon monoxide readings
✅ Testing chimney draft pressure
✅ Motorized vent damper operation
✅ Draft hood spillage testing
✅ Why combustion safety matters
⚠️ Low CO doesn't automatically mean a boiler is venting safely! Always verify draft, spillage, and manufacturer specifications.
