A minimum clearance of at least 300mm must be left between the terminations
and the flue terminal must be directed away from the air intake terminal.

All parts of the system must be constructed in accordance with BS 5440 Part 1,
except where specifically mentioned in these instructions.
All pipe work must be adequately supported.
All joints other than push-on or plastic compression connectors must be made
and sealed with solvent cement suitable for muPVC pipes and conforming to BS

Consideration must be given to Corgi/Gas Safe bulletin TB200/TB008 regarding
flues in voids.
The boiler casing must always be correctly fitted to the boiler when leaving the

The C45, C40P and C55(P) are room sealed appliances and therefore do not require
purpose provided ventilation to the boiler room for combustion air.
