2.3 Condensate in the flue gas system
Condensate can form in the flue gas system when the air heater is heating up. Normally, this evaporates
again when the unit is in operation for a longer period of time.
Smaller units are more sensitive to condensate formation. Therefore, place a T-piece with flue gas pipe kit
if the following length is exceeded:
Type
Flue gas exhaust length
GSX 20
2 metre
GSX 35
3 metre
GSX 55
3 metre
GSX 75
5 metre
GSX 90
-
If a unit is placed in a cold room, colder than 10°C, condensate is more likely to form. The above lengths
must then be shortened by 1 metre.
The condensate pipe, with siphon, must be protected against frost. The siphon must be connected to the
sewer with an open connection. The condensate drain must comply with national and local regulations.
2.4 Gas connection
The installation of the gas pipeline and gas tap must comply with the relevant local and/or national
regulations. The gas tap must be positioned within reach of the appliance [3]. If the connection line is
subject to pressures above 60mbar, this gas tap must be closed. If there is any possibility of the presence
of dirt in the gas, use a gas filter. Always blow through the gas pipe in compliance with the regulations
prior to operating the appliance. If the appliance needs to be converted to a different type of gas than that
indicated on the type plate, the supplier of the appliance must be contacted. The supplier can advise you
which parts must be replaced in order to ensure correct operation of the appliance with the desired type
of gas. Conversion to a different type of gas is not permitted in Belgium.
2.5 Electrical connection
Installation must comply with the relevant local and/or national regulations. Ensure that there is a correct
connection group with a mains fuse. The electrical diagram is displayed on the appliance. A basic diagram
for the GSX appliance can be found in chapter 8 and 9 Electrical diagram.
PLEASE NOTE:
– The appliance must be adequately earthed. The appliance must be fitted with an isolator switch
which interrupts phase and zero (not earth).
– The isolator switch must be accessible at all times.
– Never, under any circumstances, allow the supply to the appliance to be interrupted by other
switches. This could result in the appliance overheating.
– The unit is phase sensitive.
3.0 Controls
3.1 Room thermostat and reset button
The room thermostat must be located at a height of approx. 1.5m and not directly within the flow of
warm air. Connect the room thermostat using a shielded data cable in accordance with the wiring diagram
supplied for the appliance. Refer also to the technical information handbook supplied with the room
thermostat. Incorrect connection will render the manufacturer's warranty void.
