Classification Due To Discharging Flue Gases - REMEHA Quinta 115 Technical Information

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 B23P: Conventional room ventilated boiler without draft diverter. Air supply from
boiler room: flue gas discharge on roof, metal flue gas discharge with CE
symbol, meets pressure class P1.
Type C13: Room sealed boiler, connected to combined wall outlet.
Type C33: Room sealed boiler, connected to a combined roof outlet.
Type C43: 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.
See also Par. 7.3.6.
NOTE: the boilers can be installed on a flue dilution system, but must have a total flue
break to avoid boiler controls being affected by the flue dilution fan pressures. For full
details please contact Broag.
