 Cleaning Ts simplify the cleaning of the chimney.
 Seal all connections of the chimney connector with heat resistant putty.
 If there are drilled orifices in the connection collar of the appliance, secure the chimney
connector to the stove collar, using the appropriate screws. This ensures the adjustment
and prevents vibrations which could lead to a separation of the connections.
Caps
There is a wide variety of caps for chimneys.
It is important for the cap to be well secured and for the separation between the chimney is at
least the same as its diameter.
Flue shut-off valve
 In general, it is not necessary to use a flue shut-off valve in a correct installation.
 Some installations, however, may benefit from a flue shut-off valve, such as high
chimneys which may create stronger flues than normal.
 In any case, a flue shut-off valve may help to regulate the flue. A solid fuel appliance
requires a flue of between 1.5 and 2.5 mm.c.a. (See manufacturer's characteristics) (See
the chapter on Technical Data).
 If the chimney flue is greater, it is advisable to install a flue shut-off valve.
 Flue shut-off valves should never fully close the smoke passage. A minimum space of 20
% should always remain free.
Linings, protectors...
 Respect the manufacturer's recommended clearances to combustible surfaces of the
stove and the chimney pipe.
 If this is not possible, protect these materials with the appropriate protectors.
 There are special protectors to install on combustible walls when the chimney connector
passes close by or through them. The aim is to protect the wall against fire.
 A wall protector should be installed when a chimney connector is installed through a
combustible wall or close by and is susceptible to damage.
 The wall pass-through protects the wall internally from combustion. This part should be
used when the chimney is connected through walls or ceilings.
Chimney Pipe
Chimneys for solid fuel appliances should be masonry built or prefabricated with materials
which withstand high temperatures.
Therefore, if you are going to build a chimney for your stove, there are two alternatives:
There is not much difference in terms of performance and operation between metal and
masonry chimneys.
Whenever possible, locate your chimney inside the house, hence obtaining a better flue, less
creosote build-up and a longer duration.
Do not install your stove without checking that the chimney is valid for use.
 Masonry Chimneys.
 Metal Chimneys
