Piazzetta MP 973 - Using an External Flue; Hood Grille

An external ue can be used provided it complies with the following
requirements:
- use only insulated stainless steel pipes (double-lined) xed to the
outside wall of the building (Fig. 21);
- there must be an inspection opening at the base of the ue to permit
periodic checks and maintenance;
- the ue must be tted at the top with a chimney stack with down-
draught cowl, also ensuring compliance with the safety distance from
the roof ridge as outlined in the section entitled “CHIMNEY STACK”.
a Ensure that all installation work is carried out to professional
standards.
The hood grille has the function of allowing air to pass from inside
the hood to the environment or vice versa if the Multifuoco system is
installed.
Warm air comes out of the hood grille with the natural convection
system and it is therefore necessary to maintain the safety distances
from ammable materials such as: ammable ceilings or walls, ledges/
beams, furniture, curtains, etc.. The hood grille must be installed at least
50 cm from the ceiling and with at least 30 cm safety distance to the
sides.
• For the hood grille size, see the “TECHNICAL DATA” paragraph.
a Two non-closable hood grilles must be installed without
connecting them to the stove so that the warm air that has
stratied inside the lining wall can ow out.
a With a ceiling over 3 metres high, two NON-CLOSABLE hood
grilles must be installed on the hood lining at a height of 30
cm from the ceiling to allow the stratied air to ow out.
