TL;DR
A combustion safety test is the series of checks, worst-case depressurization, draft verification, spillage testing, and carbon monoxide measurement, performed on fuel-burning appliances before and after a home is air-sealed or insulated. Tightening a house changes its pressure balance, and exhaust fans or a dryer can pull flue gases backward down a water heater vent.
What it means
A combustion safety test is the series of checks, worst-case depressurization, draft verification, spillage testing, and carbon monoxide measurement, performed on fuel-burning appliances before and after a home is air-sealed or insulated. Tightening a house changes its pressure balance, and exhaust fans or a dryer can pull flue gases backward down a water heater vent. BPI protocols and many weatherization programs make this test mandatory, so it should appear in any reputable insulation contractor's scope.
