Vented Combustion Appliances—gas and fuel oil water heaters, furnaces, boilers, even fireplaces—need to exhaust all of their combustion by-products, all the time, outside the home. Carbon monoxide is especially dangerous because it is odorless, colorless, tasteless. If any of these appliances is atmospherically-vented or has induced draft or even if they are power-vented, we need to test to see if conditions in the home can create back drafting (back drafting is combustion exhaust rolling out of the intended exhaust pathway and into the home).
Combustion Safety Testing
Vented combustion appliances are tested for back drafting. Back drafting is combustion exhaust rolling out of the intended exhaust pathway into the home. Back drafting can be extremely hazardous since exhaust fumes like Carbon Monoxide is odorless and tasteless making it impossible to detect just by the human sense. This is why it is important for us to conduct a combustion safety test for all appliances.
