strate compliance with Building Regulations and should be
provided to the customer for future reference.
Installers are required to carry out installation, commission-
ing and servicing work in accordance with the Benchmark
Code of Practice which is available from the Heating and
Hotwater Industry Council who manage and promote the
Scheme.
Benchmark is managed and promoted by the Heating and
Hotwater Industry Council.

3.1 Compartment Ventilation
The boilers are very high efficiency appliances.
As a consequence the heat loss from the appliance casing
during operation is very low.
Compartment ventilation is not required as the products are
only certified, and can only be fitted with a concentric flue
system.
