5.1.1.
Flue material
Only use CE marked flue material from the manufacturers
Muelink & Grol (M&G) and Burgerhout.
Use type Alu-fix with a minimum temperature class of
T120 P1.
Use flue pipes with the same diameter as the flue spigots
on the heater.
Contact your supplier to purchase these flue materials.
NOTICE
Different manufacturers use different
connections systems for flue pipes. Do not combine
systems from different manufacturers.
5.2. Flue length (max.)
The maximum straight length between the air heater and
its flue terminal for both orientations is:
•
Horizontal & vertical: 9 meters.
Bends that are used in the connection between an air
heater and the flue terminal cause a decrease in pressure:
•
Using a 90° bend decreases the maximum length
of the connection by 2 meters.
•
Using a 45° bend decreases the maximum length
of the connection by 1 meter.
For further information regarding the flue system, please
contact your supplier.

5.3. Condensate discharge system
Condensate is discharged from the air heater/flue terminal
through a discharge pipe. The discharge pipe (Ø40 mm) is
located on the bottom of the heater (figure 18).

Figure 18 - The condensate discharge pipe
To install the condensate discharge system, do the
following:
•
Connect the discharge pipe to the siphon that is
delivered with the air heater.
•
Connect the other end of the siphon to a discharge
system with the following requirements:
– Min. Ø25 mm pipes.
– Min. downward inclination of 50 mm/m.
– Max. horizontal length of 5 m.
•
Install a second siphon with an open inlet. This
ensures that the condensate can always exit the
heater.
•
Fill both siphons with water. This prevents flue
gases from flowing into the room or pipework.
•
Connect the discharge system to the sewer.
WARNING!
Do not let the condensate drip on the roof or
roof edge of the building. This can cause dangerous ice to
form in the winter. Condensate must always be discharged
to the sewer.
CAUTION!
Never close the air heater's condensate
discharge pipe. This will cause the heater to stop working.
CAUTION!
In the winter, ice can form and block the
condensate discharge pipe. Protect the condensate drain
from freezing to prevent this.
NOTICE
The condensate discharge system must be
