The Remeha Gas 210 PRO is suitable for conventional room ven-
tilated or room sealed operation. Specify at the time of ordering if
the boiler is to be supplied for room sealed operation. In that case,
the boiler will be supplied with a purpose-designed room sealed
terminal, air supply connection and some accessories. The air
supply connection should rest on the heat exchanger underneath
the boiler casing after removing the standard perforated air inlet
cover. Horizontal components in the flue gas discharge system
should slope towards the boiler. Horizontal components in the air
supply system should slope towards the supply opening.
Room sealed terminals should comply with the national require-
ments for both horizontal and vertical outlet constructions.
Care should be taken when siting flue exit positions as a vapour
plume will be visible when the boiler is operational (flue gas tem-
perature will be less than 80°C resulting in the water vapour con-
densing out on contact with the air).
Classification due to discharging flue gases
The boiler is approved according to CE with classification:
Type B23: Conventional room ventilated appliance without draft
diverter. Air supply from boiler room; flue gas discharge on roof.
Type B23 : Conventional room ventilated boiler without draft
P
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 appliance, connected to combined roof
outlet.
Type C43: Room sealed appliance in cascade configuration, con-
nected via two ducts to a common duct system serving more than
one appliance.
Type C53: Room sealed appliance, connected to separate ducts
for the air supply and flue gas discharge, terminated in zones of
different pressure.
Type C63: Room sealed appliance, supplied without the terminal
or the air supply and flue gas discharge ducts.
Type C83: Room sealed appliance, connected to separate air
supply and flue gas discharge duct, with flue gas discharge duct
always in underpressure.
The open flue version extracts the necessary combustion air from
the plant room or compartment. A table showing the maximum dis-
charge lengths can be found in Section 7.2.1.
