La Nordica Super Max [17/68] Chimney pot

SUPER MAX - SUPER JUNIOR

7191051 17

The stove is equipped with controls of primary and secondary air by which it is adjusted the combustion air.

1A - PRIMARY air register (Picture 6 at page 61)

With the register below on the door of the hearth it is adjusted the passage of air through the drawer of ash and the grate in the fuel

direction. The primary air is necessary for the combustion process. The ash drawer must be regularly emptied, so that the ash does

not obstruct the primary air entry for the combustion. Through the primary air the re is also kept alive.

During wood combustion, the register of primary air must be opened only for a while, because otherwise the wood burns fast and the

stove may overheat. The register is open when the lever is completely pulled out. The register is closed when the lever is introduced

(see chapter NORMAL OPERATION).

2A - SECONDARY air register (Picture 6 at page 61)

On the over part of the door there is the secondary air control. Also this control must be opened (then moved to the right), especially

for wood combustion, so that unburnt carbon does not undergo a post-combustion (see chapter NORMAL OPERATION).

The adjustment of the registers necessary to reach the rated caloric yield is the following one:

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 ues 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. Picture 1 at page 58 shows some example solutions.

The minimum section must be 4 dm

(for example 20x20 cm) for appliances whose pipe dimensions are less than 200 mm, or 6.25

(for example 25x25 cm) for appliances with a diameter of more than 200 mm.

The draught created by your ue must be sufcient but not excessive.

A section of the ue which is too large can present a volume which is too large to heat and therefore cause operating difculties 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 ue must be at a suitably distance from ammable or combustible material using suitable insulation or an air space.

It is FORBIDDEN to pass system piping or air ducts inside the ue. It is also forbidden to create moveable or xed openings on the ue

itself, for the connection of further different appliances (See chapter CONNECTING A FIREPLACE OR OPEN HEARTH TO THE FLUE).

6.1. CHIMNEY POT

The ue draught depends on the suitability of the chimney pot.

It is therefore essential that, if built in a handcrafted way, the exit section is more than twice the internal section of the ue

(Picture 2 at page 58) .

As it must always go past the ridge of the roof, the chimney pot must ensure exhaust even in the presence of wind (Picture 3 at page 59).

The chimney pot must meet the following requirements:

• Have an internal section equivalent to that of the chimney.

• Have a useful exit section of double the internal section of the ue.

• Be built so as to prevent rain, snow or any foreign body entering the ue.

• Be easy to inspect, for any maintenance and cleaning operations.

6.2. CONNECTION TO THE CHIMNEY

Products with automatic door closing (type 1) must operate, for safety reasons, with the furnace door closed (except during the fuel loading

or ash removal phases).

Products with non-automatic door closing (type 2) must be connected to their own ue.

Operation with doors open is only allowed when supervised.

The connection pipe to the ue must be as short as possible, straight horizontal and positioned slightly in ascent, and watertight.

Connection must be carried out with stable and robust pipes,comply with all current Standards and Regulations and to those envisioned

by the law, and be hermetically secured to the ue. The internal diameter of the connection pipe must correspond to the external diameter

of the appliance ue gas exhaust stub pipe (DIN 1298).

ATTENTION: as far as concern the realisation of the ue connection and ammable materials please follow the requirements provided by
