If you remove one or both of the upper deflectors, located in the steel
hood above the fire mouth, it lets the smoke rise vertically without
obstructions towards the flue pipe.
Always remove the higher deflector first (the smaller one). Only
after re-lighting the fire and checking operation, remove the second
lower deflector (the larger one).
The deflectors are simply set on internal brackets. Therefore, to remove
them, just move them in the direction of the arrow as shown in figure
29.
Removal of the deflectors should not become a matter
of routine. You should only do it when there is no other
way or improving an old or small flue pipe short of
rebuilding it.
Removing the deflectors without due reason causes smoke
to exit more rapidly and decreases thermal exchange, with
lowers the performance of the fireplace stove. This does not
happed if draught is insufficient because the smoke already
spends too much time in the combustion chamber and has
time to make the proper exchange.
This should be carried out by the installer at the
moment of test lighting. Never operate the fireplace
stove with only the upper deflector (i.e. the smaller
one) as this may force smoke towards the fire door
and allow smoke to get into the room.
The steel deflectors get very hot. Therefore, before
removing them, make sure the fireplace stove has
been shut down and has cooled for some time.
5.7. COOKING FOODS
Only certain models of the Airsystem line are suited for cooking foods
on the grille with the fire door open (Airsystem F80). Therefore, if you
want to cook on a model that is not set up for it, it is advisable first to
form a bed of coals with no flames. Then open the door only to turn
the food over on the grill, which must fit in the fire bed.
5.8. EMERGENCY SITUATIONS
If for any reason the stove fire needs to be suddenly and quickly put
out or a fire in the flue pipe needs to be put out, proceed as follows:
• If time allows, remove the grate and ashes, using a metal
container.
• Put the fire out rapidly by means of a dry carbon dioxide (CO
2
)
extinguisher.
