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.
Conventional open flue installation:
Combustion air for the boiler must be provided to the room/compartment in accordan-
ce with BS 6644 and BS 5440.
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 sea-
led horizontal or vertical terminal unit.
Additional ventilation will be required to the room/compartment in accordance with BS
6644 and BS 5440 (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.
7.3.3 Material and installation
Flue gas discharge:
Rigid single walled: stainless steel (316), aluminium or plastic (to comply with building
regulations).
Flexible: stainless steel (316).
Construction: all joints and seams should be gastight and watertight with the horizontal
runs graded towards the boiler to allow condensate free drainage to the boiler
The flue outlet should terminate with reduction cone and bird guard only (chinamans
hat or GLC type terminals etc. should not be used).
Use vertical flue terminal MG 87973 (Quinta 45) or MG 87969 (Quinta 65) for classifi-
cation C33.
