The appliance can only be installed in a room which
meets the ventilation regulations in force. But, in any
event the room must have a permanent vent of minimum
free air area, see below.
IMPORTANT: THE LOUVRED AIR INTAKE AT THE
BOTTOM FRONT OF THIS APPLIANCE MUST BE
KEPT CLEAR OF ANY OBSTRUCTIONS
Detailed recommendations for air supply are given in the
Building Regulations, and in BS 5410: Part 1. The
following notes are intended to give general guidance.
1.
Combustion and ventilation air supply to oil fired
appliance has to comply with the Building Regulations
and with BS 5410: Part 1. The air supply requirement for
oil fired appliances is 550mm
2
per kW of maximum rated
output above 5kW. These requirements are illustrated in
OFTEC Technical Book No.3.
2.
The combustion air supply to open flued appliances
should normally be provided at high level into a room
where it will not cause discomfort by creating a cold
draught across the floor.
3.
If combustion air is supplied through an under floor
duct the grilles at each end should be positioned in the
vertical plane to reduce the risk of blockage. Ducts should
be sized so as to reduce resistance to air flow.
4.
The ventilation requirement for kitchens in Part F of the
Building Regulations is for mechanical extract at the rate
of 60 litres per second or 30 litres per second if the fan is
incorporated in a cooker hood.
Background ventilation is also required, either by
producing a constant mechanical extract rate of one air
change per hour or by having ventilation openings of not
less than 4000mm
2
.
5.
Extract fan should be positioned as far away from the
appliance as possible and should have a sufficient
dedicated air supply. To undertake a test the oil fired
appliance should be set in operation and the doors and
windows of the room containing it should be closed. The
extract fan should then be run at its maximum setting. The
oil fired appliance should be observed to operate
satisfactorily both before and after the fan is switched on.
6.
It is preferable for the air supply for an extract fan to be
located where it can serve the fan without the air stream
passing close to the oil fired appliance.
7.
Oil fired appliances must not draw combustion air from
a garage.
