THE FLUE PIPE

FLUE PIPE CHARACTERISTICS

It is essential that the flue is suitable for the appliance to work correctly.

The flue pipe must conform to the regulations in force and be kept in perfect condition.

The flue system should be inspected by a technician experienced in flues before installing the appliance, and then be checked at least once a year.


DEPRESSION: the optimal depression (flue draught pressure) for DeManincor’s cookers is 0,12 mbar. 

At a depression below 0,12 mbar, the fire will burn too slowly and form carbon residue excessive gases.
If instead depression is any greater, combustion will be too fast and not transmit as much heat to the oven and the heating plate.


Below are several instructions on fitting the flue pipe. Noncompliance with these could compromise the appliancés yield and cause problems with combustion:

• its height must not be less than 4/5 linear metres from the connection to the stove to the base of the chimney pot; the flue can be narrower if its height is any greater;
• it must be properly sealed and insulated; make sure the inspection panels close properly and that there are no cracks on any part of the flue pipe;
• the inside of the pipe must be smooth and the same width all the way up;
• the flue must be as straight as possible and the chimney pot must be in a suitable position and at an appropriate pitch, as indicated in the diagrams and examples below;
• the chimney pot must be double the width of the flue pipe.




FLUE PIPE DIMENSIONS

Guideline for sizing the flue as a function of it’s height:



If this is not feasible you should contact a flue specialist.


CROSS-SECTION: the flue pipés cross-section depends on the height of the flue and the thermal power of the installed cooker.
To ensure the optimal yield of our cookers we recommendyou use circular flue pipe with smooth interior lining and of the same length all the way up.



INSULATION: flue draught pressure also depends on the difference in the temperature of the hot flue gases and that of the air outside. The flue pipe must be insulated to restrict absorption of heat into the walls and therefore avoid condensation, which can cause tarry residues. Use only suitable heat- and corrosion-resistant materials conforming to building and fire-prevention regulations. You should not use flue pipes comprising simple or flexible metal tubes, cement tubes for vents, etc.


CONNECTION TO THE FLUE PIPE

The cooker is delivered with the connection corresponding to the flue exit chosen when ordering:

   
 
Thermo cooker ever Ø14 and Thermo stoves ever Ø15.




EACH COOKER SHOULD HAVE ITS OWN FLUE PIPE. DO NOT USE THE SAME FLUE PIPE FOR MORE THAN ONE APPLIANCE.


THE COOKER SHOULD BE CONNECTED TO THE FLUE PIPE AVOIDING AS FAR AS POSSIBLE ANY BENDS, DIVERSIONS AND DOWNWARD OR HORIZONTAL SECTIONS.


Connecting pipes must be perfectly sealed to each other and to the stove and flue pipe. These precautions must be taken:
• use a seal to avoid infiltration of air into the flue;
• the pipe must not be narrower at the end;
• the end of the pipe must not protrude into the flue.
