What causes a furnace explosion?
When your thermostat calls for heat from the furnace, a gas valve opens, sending gas to the furnace’s burners to ignite the gas. The gas keeps building until—BOOM—it reaches a flame and finally ignites, causing a small explosion in your furnace.
Can a boiler backfire?
This oil burner backfire, called a “puff back,” forces soot or smoke through the heating exhaust system and into the owner’s property. A puff back may be an explosion that releases a large amount of soot into the building, or it can occur in small instances each time a furnace or boiler gets ignited.
What does it mean when an oil burner backfires?

What causes an oil burner furnace to get late ignition?
Here are a few of the common causes of late ignition on an oil burner furnace. If the O-rings near the fuel filter are old or corroded, they may be leaking air into the fuel line. If this is the case, the fuel pump must pump the air out of the lines before it can begin pumping fuel to the igniter.
What causes an oil burner to push out extra fuel?
But nearly all of the problems that are at the root cause of a puffback are maintenance or installation errors or omissions, including: Failing to detect and fix an oil line leak. Air entering the line is a common cause of push-out of extra, un-burned fuel at the end of an oil burner on-cycle.
What happens if you push the reset button on an oil burner furnace?
Not only could the problem lead to a dangerous explosion if the reset button is pushed too many times, but if the furnace fails when the temperature is below zero, it could make living in the house very uncomfortable. Here are a few of the common causes of late ignition on an oil burner furnace.
What causes a backfire in an oil burner?
Atomized Explosions. Essentially, backfires occur when your oil furnace misses ignition: If the burner doesn’t ignite as intended, atomized oil fumes can build up; when ignition finally occurs, the fumes typically cause a small explosion.
What causes a puffback in an oil fired furnace?
Forced air, oil-fired heating system puffbacks tend to be the messiest, as oil creates more soot than gas, and the ductwork for the forced air system can spread that soot to every room in the home. What causes a puffback? Regardless of fuel type, furnaces and boilers should have annual system maintenance.
Why do I have soot coming from my oil burner?
Also look for heating oil drips or leaks around the system. An oil burner or oil piping leak causes improper and unsafe oil burner operation – so in addition to possibly leaking oil out, air leaks in, the burner doesn’t fire properly, and there’s risk of sooting or a puffback explosion. But I can’t assess the risks you question from an e-text.
