Smoke Control Areas

Under the Clean Air Act local authorities may declare the whole or part of the district of the authority to be a smoke
control area. It is an offence to emit smoke from a chimney of a building, from a furnace or from any fixed boiler if located
in a designated smoke control area. It is also an offence to acquire an "unauthorised fuel" for use within a smoke control
area unless it is used in an "exempt" appliance ("exempted" from the controls which generally apply in the smoke control
area).
The Secretary of State for Environment, Food and Rural Affairs has powers under the Act to authorise smokeless fuels
or exempt appliances for use in smoke control areas in England. In Scotland and Wales this power rests with Ministers in
the devolved administrations for those countries. Separate legislation, the Clean Air (Northern Ireland) Order 1981,
applies in Northern Ireland. Therefore it is a requirement that fuels burnt or obtained for use in smoke control areas have
been "authorised" in Regulations and that appliances used to burn solid fuel in those areas (other than "authorised"
fuels) have been exempted by an Order made and signed by the Secretary of State or Minister in the devolved
administrations.
Further information on the requirements of the Clean Air Act can be found here :
http://smokecontrol.defra.gov.uk/
Your local authority is responsible for implementing the Clean Air Act 1993 including designation and supervision of
smoke control areas and you can contact them for details of Clean Air Act requirements”

“The Klover SMART 120 (models - SM120, SM120-BP, SM120-P, SM120-B) have been recommended as suitable

for use in smoke control areas when burning wood pellets.”

The manufacturer reserves the faculty to make any modifications to the product in order to improve its
performance.
The given heat output can change according to the pellet used.

Pellet features

The central heating cooker has been tested with all types of pellets available on the market. The

pellets used must have the following features:

 Diameter 6 mm;
 Maximum length 35 mm;
 Maximum humidity content 8 – 9 %;
 100% wood. Total absence of additives.
 1.1 % maximum ash residue

For a good performance of the central heating cooker, we recommend using good quality pellets.
Pellets should be poured into the tank using a shovel, and not directly from the bag.

To recognise good quality pellet, make sure:

 It is made up of constant diameter cylinders, and has a smooth, glossy surface;
 There is not a lot of sawdust inside the packaging;
 If the pellet is poured into a container full of water, it will sink if it is good quality, and

it will tend to float if it is not;

 The references of quality certifications and in particular compliance with

international standards such as EN 14961-2 Wood pellet class A1-A2 (maximum
moisture level of 10%), should be indicated on the packaging;

 Packages are intact as pellet tends to absorb humidity. Humidity not only reduces

the calorific value and increases flue gas, but swells the product, which could create
problems in the central heating cooker.

International standards must be complied with for pellet manufacture as already happens in
France, Austria, Germany, and recently some Eastern countries, which also have to comply with
DIN 51731 and O-NORM M7135 standards in the production phase. These standards establish the
minimum values to check pellet quality. In Italy there are not official rules, but it is recommended
using pellet meeting the previously-mentioned standards.

The use of poor pellet or any other material can damage the central heating cooker features,

voiding the warranty and exempting the manufacturer from all responsibility.

In order to ensure problem-free combustion, the pellets must be kept in a dry place.

17

REQUIREMENTS OF THE PLACE OF INSTALLATION

Positioning

The first step to ensure the best installation of the central heating cooker is to identify an excellent

location; in this regard, take the following elements into account:

 The possibility of creating an external air intake;
 The possibility of creating a straight flue with possibly coaxial central heating cooker

output;

 Proximity to the main liquid collector and /or the boiler if one already exists);
 Proximity or ease of connection to the water system;
 Ease of access for cleaning the central heating cooker, the exhaust gas ducts and the

flue.

The central heating cooker must be installed on a floor with suitable load capacity. If the existing

building does not meet this requirement, appropriate measures (e.g. load distribution plate) must be

taken.

Once you have found the best location for the cooker arrangement, position it following the directions

given below.

The minimum safety distance from flammable materials must be at least 200 mm from the sides

and back of the central heating cooker.

Spaces around and above the central heating cooker

The figure below shows the minimum measures to be met when positioning the central heating

cooker in relation to the walls.

PARETE POSTERIORE

PARETE LATERALE

PARETE LATERALE

50 cm

50 cm

The hood assembled above the central heating cooker must be at least 70 cm away from its upper

part (also see technical features in the instructions manual attached to the hood to be installed).

Furniture and mobile objects must be positioned at least 10 cm away from the equipment side walls;

these items should be easily removable in case of maintenance work. In any case they should

be moved before any operation by the authorised Technical Assistance Centre for easy

access to the equipment sides.

Hanging shelves or building countertops above the central heating cooker, especially if the latter

have low heat resistance, is not recommended. Shelves or countertops should in any case be at

least 70 cm away from the upper cooking plate.

Protect all structures that can catch fire from heat radiation.

REAR WALL

LATERAL WALL

External air vent

While running the central heating cooker draws air from the room in which it is installed; It is

essential, therefore, that the air is restored through an external air vent.

An air vent must be made at the back of the equipment (15 cm diameter hole), at a height of

20 cm from the ground, near the central heating cooker intake pipe (see figure A and

Connections technical sheet).

if the rear external air vent does not draw air directly from outside the home, a further hole in an

adjacent room must be made provided it communicates with the outside of the home (minimum

diameter 15 cm).

If an air vent cannot be made on the heating cooker rear wall, keep it at least 5 cm away from the

rear wall and drill a hole (diameter as above) in a perimeter wall of the room where the central

heating cooker is installed.

The hole must be protected externally with a fixed grid. Periodically ensure the grid is not

obstructed by leaves or the like, thereby preventing air passage.

The UNI 10683 standard PROHIBITS the withdrawal of combustion air from garages, fuel

stores, or businesses involving a fire hazard.

Do not connect the external air vent to the central heating cooker through piping. If there are

other heating or suction appliances in the room, air vents must ensure the necessary air

volume required for the proper operation of all devices.

In the room where the central heating cooker is to be installed, only sealed equipment (e.g. C

type gas equipment, according to the UNI 7129 Standard), or equipment that does not cause

depression with respect to the external environment can be kept or be installed.

Extractor fans may cause a malfunction in the central heating cooker when used in the same room

or operational space as the cooker.

Figura A

Flue and connection to the same flue - Chimney

The flue is a key element for the proper operation of the central heating cooker. The minimum section

of the flue must be the one indicated in the central heating cooker specifications (120 mm). Each

central heating cooker must have its own flue, without other intakes (boilers, fireplaces, stoves,

etc…). The flue size is closely related to its height, to be measured from the central heating cooker

outlet to the chimney base. To ensure draught, the chimney flue outlet surface must be twice as big

as the flue section.
