Design Guide
MANDATORY REQUIREMENTS
Connection to an appliance which is not connected to the fuel supply, should be carried out
by a competent person. We recommend the use of HETAS approved installers for solid fuel
applications. If installation is carried out by a non HETAS registered installer, the installation must
be certified by a local Building Control inspector. Connection to an appliance that is connected to
the fuel supply must be carried out by a Gas Safe (Gas) or OFTEC (Oil) registered installer.
The design guide must be read in conjunction with the detailed component installation
instructions.
