7.3.2 Classification due to discharging flue gases

Classification according to CE:

Type B23:

Conventional room ventilated boiler without draft diverter. Air supply from boiler room:

flue gas discharge on roof.

Type C13:

Room sealed boiler, connected to combined wall outlet.

Type C33:

Room sealed boiler in cascade configuration, connected via two ducts to a common

duct system serving more than one boiler.

Type C53:

Room sealed boiler, connected to separate ducts for the air supply and flue gas

discharge, terminated in zones of different pressure.

Type C63:

Room sealed boiler, supplied without the terminal or the air supply and flue gas

discharge ducts.

Type C83:

Room sealed boiler, connected via two ducts to a common duct system serving more

than one boiler. (flue gas discharge always under pressure)

Conventional open flue installation:

Combustion air for the boiler must be provided to the room/compartment in

accordance with the British Standards.

For maximum flue length, see table in Par. 7.3.4.

Room sealed installations:

It is unnecessary to provide separate combustion air to the room/compartment as this

is supplied direct to the boiler via the concentric or eccentric system and the room

sealed horizontal or vertical terminal unit.

Additional ventilation will be required to the room/compartment in accordance with the

British Standards (compartment ventilation).

For maximum flue/air inlet length, see table in Par. 7.3.5.

For installations where supply and discharge points are in two different pressure zones

(eccentric only), please contact Broag Technical Dept. for further details and advice.
