  • Page 14: Chimney Cowl

    03. INSTALLING THE PRODUCT 03.3 CHIMNEY COWL A properly installed chimney cowl ensures optimum stove functioning. The anti-downdraught chimney cowl consists of a number of components whose outlet section sum always doubles the vent pipe section. Make sure the chimney cowl is at least 150 cm above the roof top so that it is fully exposed to the wind.

  • Page 15: Draught

    03. INSTALLING THE PRODUCT 03.4 DRAUGHT Fumes heat up during combustion, increasing their volume. Their density is therefore lower than the one of the surrounding colder air. This difference between the inside and outside temperatures of the chimney results in a negative pressure which increases proportionally to the vent pipe length and the temperature.

  • Page 16: Stove Efficiency

    03. INSTALLING THE PRODUCT 03.5 STOVE EFFICIENCY Highly efficient stoves may pose difficulties for fume extraction. In order for a vent pipe to work properly its internal temperature must increase as a consequence of the fumes generated during combustion. Importantly, the efficiency of a heater is determined by its ability to transfer most of the heat produced to the environment to be heated: consequently, the greater the efficiency of the stove, the "colder"...

  • Page 18 03. INSTALLING THE PRODUCT • The combustion air intake must be connected directly to the outside or to adjacent rooms provided they are fitted with external air supply vents and are not used as bedrooms or bathrooms or, whenever a fire hazard exists, as storage rooms, garages, combustible material warehouses, etc.
  • Page 19 03. INSTALLING THE PRODUCT INSTALLATION EXAMPLE: ATTENTION (ONLY EV20 – EV24 MODELS) the measurement between the centre of the fume outlet and the base of the stove is 170 mm. Check that the T-coupling has appropriate measurements in order to ensure extraction of the lid for collecting of the ashes. EXAMPLE OF INCORRECT INSTALLATION: Exhaust pipes must never be fitted pointing downwards or horizontally so that fumes are discharged directly through the external wall.
