APPENDIX - IDENTIFYING THE FLUE AND INSTALLATION TYPE
See below for identification of the flue type and installation.
C13 Flue Type – for Vehicle in Motion
The C13 type utilises the Vehicle in Motion Double Flue Bracket, whereby both flues exit the vehicle wall via the
same bracket, with one flue located above the other (see below). For reference, the Exhaust Flue must always be
located above the Inlet Flue.
C53 Flue Type – Standard installation
If the installation and flues are type C53, the flues remain separate and exit the vehicle wall at least 500mm apart.
Please note: Some installations may use a single bracket to secure each flue individually, but they will still be
located at least 500mm apart.
