“Truth always originates in a minority of one, and every custom begins as a broken precedent.” Will Durant (1885-1981, bio link)
Building pressures cause problems with some combustion appliances
When exhaust fans operate to push inside air outside a dwelling (bathroom, kitchen, clothes dryer, attic fans) they go in the opposite direction of and exceed some gas, oil or wood furnace or water heater’s draft pressure or exhaust pressure. They may over power the safe operation of certain appliances.
This reversal of combustion gas flow may result in combustion gas dispersion and perhaps carbon monoxide production and exposures to poisoning inside the home or building. Have your home pressure tested when your appliances are tested by knowledgeable technicians. This test is often referenced as the CAZ test which refers to Combustion Appliance Zone.
Buildings may have been over tightened in an effort to save energy. This may result in insufficient combustion air for our fueled appliances. This building tightness may also trap pollutants inside. It is not uncommon to find sickening concentrations of CO left over in buildings from propane or gasoline fueled pressure washers, floor buffers, concrete saws, construction space heaters and other systems hours after they have been utilized.
Leaky duct work in homes that have air distribution systems and vented gas appliances can also result in opposite pressures and appliance back-drafting. Duct leakage measurement tests should be performed to quantify quality of ducted delivery air.
There are a lot of technicians working on air conditioning systems in the warmer summer months. Air flow testing is mandatory for efficient operation of treated air distribution. Testing the building’s inside pressure with reference to outside pressures during this test may reveal the cause of that water heater reversal and carbon monoxide generation.
