minimum of 50mm clearance from any part of the terminal and
be central over the terminal.
The guard should be similar to that shown in diagram 3.5.

3.5 Timber Frame Buildings
If the boiler is to be installed in a timber frame building it should
be fitted in accordance with the Institute of Gas Engineers
document IGE/UP/7/1998. If in doubt seek advice from the local
gas undertaking or Hepworth Heating Ltd.
3.6 Room Ventilation
The boiler is room sealed, so when it is installed in a room or
space, a permanent air vent is not required.
3.7 Cupboard or Compartment Ventilation
Due to the high efficiency and hence low casing temperature of
this boiler, cupboard or compartment ventilation is not necessary.
