Conditions For Good Exhaust-Out
The fireplace will work properly if in a fire chamber in proper conditions are provided: fussed power for the closed chambers and speed movement of gases for the opened.
The minimum chimney height of a fireplace is about 18 feet from a surface of burning to a chimney mouth.
But just one condition of height is not enough, there is an uneasy dependence between the form and the size of chimney section, height and geometrical parameters.
Mistakes in an estimation of all conditions can lead to bad fireplace work – smoke problem, difficulty lighting-up etc.
