HORIZONTAL FLUE Ø 60-100mm COAXIAL
5.5 AIR/FLUE SYSTEM
The flue system is a part of the appliance and is approved as such. Use only flue systems supplied by Morco
witch are approved for use with this boiler.
The standard flue kit for the FEB-24ED is a 600mm horizontal coaxial air/flue kit (part number RSF003), as
shown below.
There are various other options available, including a vertical flue kit.(part number RSF040)
Please ask for details.
The horizontal pipe may be cut down to the length required. The flue must be fitted with a .2° or 3° down-
wards incline to prevent any water or condensation from entering in the boiler.
Where a short run of less than 1 m is used, such as in a caravan holiday home, the air restrictor ring
must be inserted into the boiler flue spigot before fitting the elbow.
5.4 WATER AND GAS CONNECTION
Connect the boiler up in such a way as to leave the
connecting pipes self supporting and free from any
stress.
Check that the gas pipe complies with the require-
ments of section 4.6
In order for the boiler to function correctly and to have
a long working life, the central heating system must
be properly designed, making sure that the temper-
ature difference between the flow and the return will
not be greater then 20°C.
