VENTILATION
The ventilation requirements in the gas fired boiler standard
are also valid for oil fired boilers of the same heat input.
The ventilation requirements of these boilers is dependant on
the type of flue system used, and their heat input. All vents
must be permanent with no means of closing, and positioned
to avoid accidental obstruction by blocking or flooding.
Detail reference should be made to BS 5440 Pt. 2. The
following notes are for general guidance only:
If installed in a room or internal space then a permanent air
vent is required. The sizes for vents directly communicating
with outside air shall have a free area of 5cm
2
per kW of boiler
rated input in excess of 7kW.
If installed in a compartment, then permanent air vents are
required at high and low level. These vents may
communicate direct to outside air, or to a room/internal space.
If to room/internal space, it must itself be adequately
ventilated as above.

Note
.
Remember that boilers installed in or close to rooms in which
the atmosphere is polluted with chlorine or fluorine compounds
may be subject to high corrosion.
For example: hairdressing salons, industrial premises
(solvents), cooling equipment etc.
Boiler installed in such locations shall not be covered by the
warranty.

FILLING THE SYSTEM
Filling shall be performed with a low flow rate from a low point
in the boiler room in order to ensure that all the air in the boiler
is bled from the high point of the system.
Always stop the pump before filling.
IMPORTANT.
Instructions for starting up the boiler for the first
time after the system is fully or partly drained:
If all the air is not bled naturally to an expansion vessel which
opens out onto the air, the system must include manual
bleeder valves, in addition to automatic bleeder valves with the
capability to bleed the system by themselves when it is
operating. The manual bleeder valves are used to bleed all
the high points of the system and to make sure that the filled
system is free of air before the burner is turned on.
General
Recommendations relating to the water system are contained
in BS. 5449 and BS. 6880.
