first three air heaters in a system

 NOTICE 

 If the J14 switch of more than one air heater is 

set to the same number, the system will not work.

 NOTICE 

 The air heater must be switched off when setting 

the switches. Otherwise the settings will have no effect. 

4.5.4  ON/OFF thermostat installation

To connect the air heater to an ON/OFF room thermostat, 
do the following:

•  Connect the two thermostat wires to terminal 6 and 

7 (see figure 13 or the electrical wiring diagram in 
§11). This is a 24 V connection for the thermostat 
signal.

 NOTICE 

 Never combine these connections with the 

terminals 6 and 7 of other air heaters.

 NOTICE 

 Always use separate relays for each air heater.

 NOTICE 

 Do not connect an external power source to 

these terminals. These terminals need a dry contact.

5  Flue systems

To ensure safe and proper use, this air heater must be 
connected to a flue system. This flue system must be 
installed according to this manual as well as national and 
local regulations. A flue system consists of a flue terminal, 
piping and an optional condensate discharge system.

 CAUTION! 

 Do not use flue terminals for condensing 

appliances on non-condensing heaters. This can lead to 
water inside the flue system.

 NOTICE 

 Only use the prescribed flue material for the 

roof terminal, wall terminal and for the piping between 
the heater and the terminal. This is the only way the 
installation will be approved.

 NOTICE 

 Local regulations can require the flue terminal to 

be placed at least 0,6 m above roof level.

 NOTICE 

 Local regulations can require a minimum 

distance between the flue terminal and air ventilation 
openings on the building.
