Pellet features

The boiler has been tested with all types of pellets present on the market. The pellet 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 good boiler efficiency, we recommend the use of good quality pellets. Pellets must be poured into the tank using a shovel and not directly from
the bag.
In order to recognise pellet of quality it is necessary that:

It is manufactured with constant diameter cylinders and it has a smooth and glossy surface;

There is not a lot of sawdust inside the packaging;

If the pellet is poured into a container of water it will sink if it is a quality pellet, while if it is not, it will tend to float;

The conditions of the quality certification and in particular the 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 since pellets tend to absorb humidity. Humidity not only reduces the calorific value and increases exhaust flue gas, but swells
the product which could create problems in the boiler.
International Standards must be respected for the manufacturing of pellets as in France, Austria, Germany and recently in some Eastern countries, also
complying with the EN 14961:2, DIN 51731 and the O-NORM M7135 Standards in the production phase. These Standards establish the minimum values
in order to check pellet quality. In Italy there is no official Standard, but it is recommended to use pellets that respect the previously-mentioned Standards.
The use of poor pellets or pellets made of any other material can lead to damage of the boiler functions and can also make the warranty null and
void and make the manufacturer exempt from all responsibility.
In order to guarantee combustion without problems the pellets must be kept in a dry place.

REQUISITES OF THE PLACE OF INSTALLATION

Positioning

The initial phase for the best installation of the boiler is to determine its optimal location; the following data needs to be considered for this:

An external air vent can be made;

A straight flue and possibly coaxial at the boiler outlet can be made;

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 boiler, the flue gas exhaust pipes and the flue.
The boiler must be installed on a floor with suitable load capacity. If the existing building does not fulfil this requirement appropriate measures (e.g. load
distribution plate) must be taken.
Once the best location for the appliance is determined, it is possible to position the boiler, following the indications below.
The minimum safety distance from flammable materials must be at least 200 mm from the sides and back of the boiler.
