Chimney Pot; Connection To The Chimney; Ventilation And Aeration Of The Installation Premises - CHAUFFAGE FRANCAIS Sannover Bedienungsanleitung

CHIMNEY POT

The flue 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 flue
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).
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 flue.
• Be built so as to prevent rain, snow or any foreign body entering the flue.
• Be easy to inspect, for any maintenance and cleaning operations.

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 flue.
Operation with doors open is only allowed when supervised.
The connection pipe to the flue 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 flue. The internal diameter of the connection pipe must correspond to the external
diameter of the appliance flue gas exhaust stub pipe (DIN 1298).
! ATTENTION: as far as concern the realisation of the flue connection and flammable materials please follow the requirements provided.
The flue must be properly spaced from any flammable materials or fuels through a proper insulation or an air cavity. Minimum distance
safety 25 cm.
The chimney pressure (DRAUGHT) must be at least 12 Pa Pascal (=1.2 mm of water column). The measurement must always be carried
out when the appliance is hot (nominal calorific power). When the pressure exceeds 17 Pascal, it is necessary to reduce it through the
installation of an additional draught regulator (false air valve) on the exhaust pipe or in the chimney, according to the regulations in
force.
! For correct appliance operation, it is essential that sufficient air for combustion is introduced into the place of installation (see
paragraph VENTILATION AND AERATION OF THE INSTALLATION PREMISES).

VENTILATION AND AERATION OF THE INSTALLATION PREMISES

As the product draw their combustion air from the place of installation, it is MANDATORY that in the place itself, a sufcient quantity of
air is introduced. If windows and doors are airtight (e.g. built according to energy saving criteria), it is possible that the fresh air intake is
no longer guaranteed and this jeopardises the draught of the appliance and your health and safety.
There MANDATORY be sufcient quantity of air for combustion and re-oxygenation of the room to ensure the device will work properly.
There should therefore be vents letting air in from outside the building and enabling circulation of air for combustion even when the
doors and windows are closed.
The air inlets must meet the following requirements:
• they must be protected with grids, metal mesh, etc., but without reducing the net useful section;
• they must be made so as to make the maintenance operations possible;
• positioned so that they cannot be obstructed;
• Any extractor hoods in the room where the device is installed must not operate at the same time as this could cause smoke to enter
the room, even with the fireplace's door closed.
The clean and non-contaminated air flow can also be obtained from a room adjacent to that of installation (indirect aeration and
ventilation), as long as the flow takes place freely through permanent openings communicating with the outside.
The adjacent room cannot be used as a garage, or to store combustible material or for any other activity with a fire hazard, bathroom,
bedroom or common room of the building.
Ventilation is deemed sufficient when the room is equipped with air inlets according to the table:

Cookers
Installation in premises with fire hazards is forbidden. Installation in residential premises in which, in any case, the depression measured
during installation between the internal and external environment is greater than 4 Pa .
All national, regional, provincial and municipal laws and standards in force in the country where the appliance is installed must be
complied with.
