Installation of flue pipes

Installation of flue pipes

There are a number of ways to install flue pipes and correct installation is important to prevent chimney fires and to help ensure that smoke is quickly removed from the building. The correct method of installing flue pipes will depend on the architectural features of the building, as well as whether or not there is a masonry chimney already installed. But, whatever the specific circumstances, there are some standard guidelines that every installation should follow:

  • The flue pipe should only be used as a connecting piece between your stove or appliance and the chimney stack.
  • Stove pipes should never pass through walls, ceilings, floors or windows. Other products should be used for this purpose, such as the Twin Wall Insulated flue.
  • Avoid bends in your pipe if possible; the fewer bends, the better the upwards draft will be. UK Building Regulations and HETAS recommend no more than four 45 degree bends in any one system.

When installing a wood stove pipe, remember that the taller the chimney, the better the draft will be. After installing, be sure to also install a chimney cowl to prevent animals and rain from entering the chimney and to further improve an upwards draft.
