Flue - LA NORDICA MAMY Instructions Pour L'installation, L'utilisation Et L'entretien

2A – SECONDARY AIR CONTROL
On the hearth door there is the secondary air register. This knob must be totally moved to the right in order to open the control, especially
for wood combustion (see paragraph Table). The secondary air, passing between the double glass of the fire door, heats itself starting the
double combustion and keeping at the same time the glass clean (with open register).
B – SMOKES control / MAMY – SUPREMA
(Conversion of the cooker function to the cooker, bake oven and heating function).
The smokes control, in the style of a chromed pull push lever, can be found on the top right corner of the front side of the cooker, between
the protection bar and the oven door. This control has two settings:
HOB COOKING: when the bar is pushed to the back of the cooker, the combustion gases flow around the oven and directly into the flue
and up to the chimney. OVEN COOKING: when the control bar is pulled out, the combustion gases flow around the oven, heating it.
C – SMOKES control / ITALY Hard Top
(Conversion of the cooker function to the cooker - bake oven and heating function).
On the central part of the front side, there is the command bar of the smokes register which is an enamelled and marked knob.
When the bar is pushed on the left of the cooker, the combustion gases flow over the oven directly into the small trunk of exhaust (cooker
function - PLATE USE); when on the contrary one pulls the lever on the right, the combustion gases flow all around the oven, so that the
internal temperature is increased in an uniform way (cooker, bakeoven and heating function - OVEN USE).
To ignite the flame follow the instructions below (see Cap. IGNITION) :
• Bring the flue gas control to the cooker position (any butterfly valve placed on the flue gas exhaust pipe must also be opened).
• Open the primary and secondary air control.
• After having started the fire with small pieces of wood and waited until it is well lit.
• Bring the flue gas control to the oven position.
• Close any butterfly valve placed on the flue gas exhaust pipe must also be opened.
The control regulation during the ignition phase is the following :

6. FLUE

Essential requirements for correct appliance operation:
• the internal section must preferably be circular;
• the appliance must be thermally insulated and impermeable and built with suitable materials which are resistant to heat, combustion
products and any condensation;
• there must be no narrowing and vertical passages with deviations must not be greater than 45°;
• if already used, it must be clean;
• the technical data from the instruction manual must be respected;
If the flues are of a square or rectangular section, the internal edges must be rounded with a radius of not less than 20 mm.
For the rectangular section, the maximum ratio between the sides must be ≤ 1.5.
A section which is too small causes a reduction in draught. A minimum height of 4 m is advisable.
The following materials are FORBIDDEN and compromise the good operation of the appliance: asbestos cement, galvanised steel, rough
and porous internal surfaces.
The minimum section must be 4 dm
dm (for example 25x25 cm) for appliances with a diameter of more than 200 mm.
2
The draught created by your flue must be sufficient but not excessive.
A section of the flue which is too large can present a volume which is too large to heat and therefore cause operating difficulties for the
appliance; to avoid this, it is necessary to intubate the appliance for its entire height. A section which is too small causes a reduction in
draught.
The flue must be at a suitably distance from flammable or combustible material using suitable insulation or an air space.
It is FORBIDDEN to pass system piping or air ducts inside the flue. It is also forbidden to create moveable or fixed openings on the flue
itself, for the connection of further different appliances (See chapter CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE).
