METAL CHIMNEYS
The advantages of these chimneys are:
Easy installation.
Slight changes in the direction to the chimney
are possible, which provides greater flexibility in
the choice of where to install the stove.
Due to the existence of curved elbows, angles
which obstruct the flue are eliminated
Make sure that all of the chimney pipes are well
secured and the seals are completely tight.
1.2.2- TYPES OF INSTALLATIONS
Follow
the
manufacturer's
installing the chimney and accessories for the
appropriate clearances from the chimney to combustible materials, walls and ceilings.
There are basically two ways of installing a pre-fabricated metal chimney:
Interior or exterior installation
1.2.2.1- Interior Installation
An interior installation is when the chimney passes inside the
residence, through the ceiling and roof.
Whenever possible, choose an interior chimney. An interior
chimney heats up more quickly and retains its heat; thus
promoting a better flue and reducing the formation of
creosote.
When the chimney passes through floors and / or ceilings,
appropriate wall pass-through FIRE guards should be
installed. The insulation will have a thickness of at least 50
mm. from the chimney to the structure.
Secure the chimney pipes to the structure of your home. Do
not load all the weight of the pipes directly on to the top of
the heater.
Protect the walls with wall protectors when the chimney is not
within the safety distance and damage may arise. (See Fig.-
2)
1.2.2.2- Exterior Installation
An exterior installation is when the chimney passes through
the wall behind the appliance and then up the outside of the
building.
An exterior chimney does not benefit from the warmth of being surrounded by the building,
so it usually lowers the flue temperature with respect to an interior chimney.
An exterior chimney's flue is not as strong and may experience an increased build-up of
creosote.
If your installation is exterior, use double pipes with an insulated chamber.
Dont use horizontal pipes (Fig.3)
