Important
In low level installations in caravan
holiday homes (other than domestic
installations and boats,) a gas
dispersal hole (drop hole) should be
provided underneath the appliance in
the compartment space in which the
appliance is installed. The minimum
size of the hole should be 13mm
diameter, which gives an area of
approximately 100mm2 taking into
account any mesh or screening
applied to prevent the entry of vermin
etc. The maximum size of the dispersal
hole must not exceed 3150mm2.
The drop hole should be positioned
centrally and as close to the appliance
front as possible. The distance from
the drop hole centre should not exceed
100mm when measured to the inside
face of the installation lower plinth.
UNDER NO CIRCUMSTANCES IS
THE GAS DISPERSAL HOLE TO BE
POSITIONED DIRECTLY BELOW THE
OVEN BURNER.
Warning:
The gas dispersal hole
may be taken into consideration for
calculating Low Level Ventilation
requirements.
However, under no
circumstances should the gas
dispersal hole exceed 3150mm2
;
o r
any other low level ventilation
holes be located in the cooker
compartment.
In
adjacent
connecting compartments, low
level ventilation holes are
permitted.
Where inset or built-in construction of
kitchen equipment is employed, this
should be purpose made so that the
free air supply for combustion in the
appliance is not impeded.
