Chimney flue – A mass oven requires a chimney for evacuating the fumes out and to ensure air to the combustion. It is the difference in the temperature in the bottom and top of the chimney flue creates a Oakum that sucks smoke out. Requirements for chimney flue are, the chimney must have an internal diameter of at least 15 cm diameter. Mass oven well can run on a traditionalist chimney flue with a snooker lining. If you build a new element chimney so choose one with an internal diameter of 17 or 20 cm. The chimney must start at floor level, mass furnace has smoke outlet at floor level.
Pull problems are usually there are good vent in the mass stove when you light a day and the oven is hot, so the move is that when you open the damper. If the housing is cold, for example. A cottage or you’ve been 14 days skiing, the difference in temperature inside and out there to start the lift, and it can be a little slow to get started. If the mass stove placed in a newly built house that is very close, there is not always sufficient air for combustion, and if the hood is operating simultaneously, so you can be sure to have problems with smoke in the kitchen. If you have problems with smoke in the living room, open a window / door in the windward side so that air entering the house if you open the shelter since the air is sucked out of the house and counteract buoyancy in the chimney flue.
If you build a new house it is good to make a fresh air channel and the oven will have sufficient air. Even if one has a warm chimney flue has sufficient height and diameter, one can get out of that is not always sufficient features it may be due to several things. Tall trees and buildings can cause the occurrence of turbulence in the wind that can provide return smoke in the chimney flue, the smoke comes out in the living room, and at worst you risk a flue gas explosion in the furnace. But it is fortunately a solution.
