Connection To The Flue Pipe; Connection To An External Flue With Insulated Or Double-Wall Pipe; Connection To Flue Pipe Or Smoke Duct - MCZ Polar Installation And Use Manual

2.6.

CONNECTION TO THE FLUE PIPE

The flue pipe must have internal dimensions not larger than 20 x 20
cm, or diameter 20 cm. In the event of larger dimensions, or of the flue
pipe being in poor condition (for example cracks, poor insulation, etc.),
it is advisable to fit a stainless steel pipe of suitable diameter inside the
flue pipe throughout its length, right up to the top.
Check with suitable instruments that there is a minimum draught of 10 Pa.
At the bottom of the flue pipe, provide an inspection cap to allow
periodic checking and cleaning, which must be done annually.
Make a gas-tight connection to the flue pipe, using pipes and
connectors as recommended by us.
You must ensure that a windproof cowl is fitted which complies with
current standards.
This type of connection ensures the evacuation of the
fumes even in the event of a temporary power
outage.
2.7. CONNECTION TO AN EXTERNAL FLUE WITH
INSULATED OR DOUBLE-WALL PIPE
The external fluepipe must have internal dimensions of minimum 10x10
cm or 10 cm diameter, and maximum 20x20 cm or 20 cm diameter.
Check with suitable instruments that there is a minimum draught of 10 Pa.
Figure 10
The only type of pipe which is permissible is insulated (double-walled)
stainless steel, smooth on the inside, fixed to the wall. Flexible stainless
steel pipe must not be used.
At the bottom of the flue pipe, provide an inspection cap to allow
periodic checking and cleaning, which must be done annually.
Make a gas-tight connection to the flue pipe, using pipes and
connectors as recommended by us.
You must ensure that a windproof cowl should be fitted which complies
with the standards in force.
This type of connection ensures the evacuation of the
fumes even in the event of a temporary power cut.

CONNECTION TO FLUE PIPE OR SMOKE DUCT

For proper operation, the connection between the stove and the flue
pipe or smoke duct must have a slope of not more than 3%. The length
of the horizontal segment must not exceed 2/3 m. and the vertical
distance between one tee connector and another (change of direction)
must not be less than 1.5m.
Check with suitable instruments that there is a minimum draught of 10 Pa.
