WATER DATA
Note * : Where the associated air extraction is also by means of a fan, this shall be selected such as not to cause
a negative pressure to develop in the boiler house and to maintain the difference between inlet and extract flow
rates shown above.
The calculated extract flow rate is the actual inlet flow rate minus the appropriate figure in the table above.

Water Data
High and low level ventilation grilles shall be positioned as high and as low as practicably possible. Low level
grilles should be located within 1 metre of the floor for Natural Gas and within 250mm of the floor for LPG. High
level grilles should be positioned within 15% of the boiler room height from the ceiling. High and low level grilles
shall communicate with the same room or space where compartment ventilation is used. Where grilles
communicate directly with outside air, they shall be positioned on the same wall.
