The Fagor FEB-24ED is a wall hung, room sealed,
fan assisted, microprocessor controlled fully modu-
lating gas combination boiler for providing both cen-
tral heating and domestic hot water. It is particularly
suitable for Caravan Holiday Home and Park Home
use. Maximum heat output in either heating or hot
water mode is 23.7.kW (80.840 Btu/h), and priority is
always given to the supply of hot water.
NOTE: The central Heating power is factory set at
70% of its maximum.
The appliance flue is supplied seperately with a con-
centric air/flue duct and wall terminal, however addi-
tional extension kits, vertical flue kit are available as
optional extras.
The appliance is intended for use with sealed central
heating systems and is supplied for use with
propane gas.
The appliance includes the following components:
Induced draught fan for the extraction of combus-
tion products and induction of combustion air.
Modulating gas valve with double safety valves
Circulation pump with manual anti-seizure device
Central heating expansion vessel.
Differential air pressure switch. Prevents the boil-
er firing if there is insufficient air supply due to a fault
or blockage.
Water pressure switch. Prevents the boiler firing if
there is less than 0.5 bar in the system.
Thermistors (NTC) There are two thermistors fitted
for automatic control of the domestic hot water and
the central heating flow temperature.
Safety thermostat Shuts down the boiler in the
event of overheating. Resets after a few minutes
cooling
Electronic controls, incorporating the following fea-
tures:
- Temperature selection for central heating from
between 60 to 85°C (Pre-set between 40º to 60ºC for
under floor heating).
- Temperature selection for domestic hot water from
between 35 to 60°C.
- Continuous modulation of the gas valve.
- Flame control by ionisation
- Ignition control
- Anti-frost control in the central heating circuit.
- Anti - seizure of the pump.
