a flue, suction hood or electric at a flow rate
that will guarantee an hourly change of air that
is at least 3 times the volume of the room. Re-
member that the air necessary for combustion
is 2m3/h for each kW of nominal heat capacity
(see rating plate).
The hobs can be mounted on all units in wood,
laminated plastic, metal and granite provided
they are heat resistant (120°C).
The appliances are classified type y, therefore,
if there is a side wall it can be higher than the
hob. Fitted hobs are class 3;
These appliances can also be fitted on top of
an oven.
If the hob is fitted on top of an oven a separa-
ting panel must be used, putting it on top of
the oven, at a distance from the undercounter
of at least 100 mm. It can be perforated at the
back only to let the hob’s gas pipe and electri-
city lead through.
The dimensional characteristics of the hobs,
their housing holes and of the undercounter
units are given in the following drawings.
