What does Black smoke from chimney mean?
Check the smoke rising from the chimney. If the smoke is black, the furnace is not burning the oil completely and fuel is being wasted. Oil-fired burners are used in many parts of the country as the basic heat source for warm air and hot water heating systems. Clean the thermostat before each heating season.
What is the most likely cause of black smoke at the boiler exhaust?
The main cause of black smoke is imbalance in the air fuel ratio. This means that either their is shortage of air or the fuel supplied to injector is not being treated properly.

Improper burning is the cause of black smoke coming from a boiler. It can also be caused by oil building up in the combustion chamber due to delayed ignition. This is known as “puff back” and is dangerous as the excess oil can suddenly ignite, causing a shooting flame and potentially splattering oil out of the boiler.
Should there be smoke coming out of chimney?
As the fire in your stove burns, the hot air can rise up your chimney, taking the smoke with it. Remember, if your fire is burning correctly, you shouldn’t be seeing huge plumes of smoke anyway. Your fire should be small and hot to burn efficiently – the slower it burns, the more smoke is created.
