A number of times each year the volunteers of the Westhampton Beach Fire Department are called out for a structure fire with smoke in the premises. Some of these calls do turn out to be actual fires, but in many instances the smoke is the result of an oil burner malfunction known as a puffback. This issue is caused by incomplete combustion of oil within the burner assembly. The burner may be used to supply heat to the home or to heat water.
Often homeowners will smell oil within the home before a puffback occurs. If this happens, they should immediately contact their heating maintenance or oil supply company. Other signs that a puffback may be imminent include an abnormally noisy burner or blowing soot in the furnace or boiler area. If the residents see smoke they should evacuate the building, call 911, and contact their heating maintenance or oil supply company. If the smoke is relatively minimal, the homeowner should shut off the furnace via the emergency switch usually located either just outside the utility room or at the top of the stairs to the basement. These switches are usually identified with a red "Emergency Switch" plate. Shutting off this switch will help mitigate damage within the home.
As your local fire department, we recommend you have your burner serviced by a qualified oil heat technician on an annual basis. Most puffbacks are related to poor maintenance and it doesn't matter whether it’s a newer or older system.
Also, always keep your oil tank supply above the 1/4 level. Running your tank dry can also result in problems as the nozzle for the burner may become clogged with sludge or debris from the bottom of the tank, leading to incomplete burning in the system. Once you shut a burner off after a puffback, it should only be restarted by a qualified professional after inspection and service to minimize any negative impact on the home.
Puffbacks can make a home unoccupiable for extended periods of time and lead to costs in the ten's of thousands of dollars for remediation. The cost of regular maintenance is minimal in comparison to the possible costs in the event of a puffback.
