Very few Buckley Rumford fireplaces smoke and so far we have been able to correct them all. The examples above are typical of the problems we encounter and how we correct them.

To draw correctly a Buckley Rumford fireplace must

  • be built according to our Instructions with the right sized throat and flue, etc., and
  • be free of restrictions such as a partially closed damper or restricting cap or improper spark arrester, and
  • be vented into a chimney that draws when it's cold, which usually means that the chimney is taller than the house, and/or
  • be within a house or building that has an adequate and balanced ventilation system so that the fireplace doesn't have to fight against too much negative pressure.
