compartment, air vents are required (for cooling purposes) in
the cupboard or compartment at high and low level which
may communicate with a room or direct to outside air.
NOTE: Both air vents must communicate with the same
room or both be on the same wall to outside air.
2. Detailed recommendations for air supply are given in BS
5440: Part 2.

provided that it is modified for the purpose.
Recommendations for air supplies and details of essential
cupboard compartment design are given in BS 5440: Part 2.
7.6 Gas Supply

located at the rear of the gas service cock (Fig. 15).
3. Ensure that the pipework from the meter to the appliance
is of adequate size.
(22mm recommended at the appliance). Do not use pipes

seal for the connection of 21.5mm (¾ in) plastic overflow
pipe which should generally discharge internally into the
household drainage system. If this is not possible, discharge
into an outside drain is acceptable.
2. The pipe should run internally as much as possible and
o
with a 10 (1 in 6) fall to dispose of condensate quickly to
