NOTE 1 The container requirements may be scaled down if it is unlikely that all appliances will be used
simultaneously for long periods of time.
NOTE 2 This table is based on results that are typical for cold-winter conditions in South Africa; in
warmer conditions the requirements will be less. With experience, a registered installer will learn how
the values can be modified to suit local conditions.

It has been found in practice that the approximations given for 45 L (19 kg) containers can usually
also be used for 34 L (13/14 kg) containers.
