We are getting black dust from the Burnham boiler installed

Customer Question

We are getting black dust from the Burnham boiler installed July 2014. There seems to be no filter to be replaced. Have had 2 techs out to resolve the problem, and lastly he cleaned the filthy box and applied a gel-like substance to seal the blackened canopy. Still having black soot in kitchen. What can we do?

If you're still getting soot in the house you need to get the tech back to finish the job and clean the unit and the flue piping better. Boilers don't have a filter. Soot is only produced when the boiler is out of proper adjustment (oil fired) or when there is insufficient air for combustion with a gas fired unit. If yours is gas you need to address the combustion air issue which the tech's should have done or at least called to your attention.
