PELLET STOVES Chapter 2

USE AND MAINTENANCE MANUAL

2.4. CONNECTING THE EXTERNAL AIR INLET

The room in which the stove is installed MUST provide at least as much

airflow as is required for regular combustion of the appliance in the

room. This can be achieved via permanent apertures made in the walls

of the room to be ventilated, leading to the outside, or via individual or

grouped ventilation ducts.

To achieve this a through hole with a minimum free cross-section of

150 cm² must be drilled in the external wall near the stove. (12 cm

diameter or 10x10 cm square hole), protected by a grille on the inside

and on the outside.

The air inlet should also:

 be directly connected to the installation setting

 be protected with a grille, metal mesh or suitable protection,

provided it does not reduce the minimum cross-section.

 be positioned in such a way that it cannot become obstructed

It is not obligatory to connect the air inlet directly to

the stove (direct connection to the outside) but the

aforementioned section must ensure that

approximately 50 m³/h of air is provided.

See standard UNI 10683.

2.5. CONNECTING THE SMOKE OUTLET PIPE

When making the hole for the smoke outlet pipe you must take note of

any flammable material. If the hole must pass through a wall made

from wood or thermolabile material THE FITTER MUST begin by using

the relevant wall connection minimum diameter 13 cm) and suitably

insulate the stove pipe crossing through it using appropriate insulating

materials (thickness of 1.3 - 5 with min. heat conductivity of 0.07

W/m°K).

This instruction is also relevant if the stove pipe must cross vertical or

horizontal sections close to the thermolabile wall (min. distance 20 cm).

Alternatively, we recommend the use of an insulated industrial pipe that

can also be used externally to prevent condensation.

The combustion chamber works under vacuum. The smoke duct

through which the smoke is discharged will be under vacuum when

connected to an efficient flue pipe, as specified.
