1.0 General
1.1 Application
The GSX appliance is designed for heating industrial and other non-domestic areas. The appliances
must be installed in a xed installation, preferably above the work oor, taking into account
minimum distances. Appliance type GSX is solely suitable for the free and direct intake of the air to
be heated and the free discharge of heated air into the room.
If areas are to be heated in which corrosive vapours are present (chlorinated hydrocarbons in
particular), which are either produced directly in the area, or which may be drawn in from the
outside by the heater via a duct or an open connection, wall air heaters cannot be used because of
the risk of corrosion to the heat exchanger.

Flue gas route
Combustion air supply pipelines and combustion gas exhaust ducts should have as few bends as
possible; in general, ow resistance should be kept to a minimum and in all cases, the diameter
should be constant along the entire length. The exhaust duct may not rest on the heater, but should
be suspended efciently! Follow the bracket instructions in chapter 10. If the ue gas exhaust duct
passes along or through combustible walls or oors, the duct must be sufciently far away from the
combustible material to prevent re.
1.4 Think of your safety
If you smell gas, you must not under any circumstances:
– Ignite an appliance
– Touch electrical switches or telephone from the area in question
Take the following action:
– Switch off the gas and electricity
– Activate the operational emergency plan
– Evacuate the building if necessary
2.0 Installation
2.1 Positioning the appliance
After unpacking, check the appliance for damage. Check that the information relating to the type/
model and the electrical voltage is correct. Install the appliance and any accessories to a sufciently
solid structure [2], taking into account the minimum free space required [1].
For GSX you should use the four M10-sized suspension points [21].
2.2 Positioningtheuegasexhaustsystemandairsupply
The device only has the CE approval in combination with its ue gas system. The ue gas system
includes: single ue set vertical or horizontal, extension pipes and elbows. Table [4] indicates
which parts can be used per appliance type. The ue gas system must be installed according to the
instructions attached.
The extension pipes must be laid in parallel. In exceptional cases, for example with thick roofs or
walls, the roof or wall terminal may be extended concentrically by a maximum of 1 meter.

2.3 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 lter. 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.
2.4 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 tted 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 Roomthermostatandresetbutton
The room thermostat must be located at a height of approx. 1.5m and not directly within the ow 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.
PLEASE NOTE:
– The maximum lengths and diameters are specied in the table [26].
– Earth the cable shielding to the appliance.
– For connecting multiple appliances, see [25] + [26].

4.0 Start-up/shutdown
4.1 General
Before being packed, each appliance is fully tested for safety and correct operation. Among other
checks, the gas pressure and CO2 are set. You must however always check the gas pre-pressure.
Never turn the adjusment screws without good cause. Do not forget to instruct the user on the
proper use and operation of the appliance and peripherals.
4.2 Checks
– Switch off the electricity supply at the main switch.
– Set the room thermostat to the minimum temperature.
– Open the gas stop cock, then carefully purge the gas pipes of air and check for leaks. Under no
circumstances use a naked ame! [27]
– Close the gas stop cock.
– In the case of the GSX, check whether the vanes in the air discharge port are set to the open
position (open to a min. of 45º).
– Switch on the electrical supply at the main switch and set the room thermostat to maximum
temperature. After the purge time has elapsed, the automatic ignition control will generate an
electric spark and the safety valve on the gas control unit will open. Because the gas stop clock is
closed, no ame will appear. The automatic ignition control will lock out after 4 attempts at
ignition, each lasting about 5 seconds. After waiting for approximately 30 seconds, the automatic
controller can be reset and the same cycle can be repeated.
– Open the gas stop cock, the appliance will now start up.
– Check the ame pattern at the main burner (clearly dened inner core, even combustion).
– In the case of appliances with an external fan, check that the maximum temperature increase of
30K is not exceeded.
4.3 Checkthattheroomthermostatisfunctioningcorrectly
If the setting is lower than the ambient temperature, the burner will extinguish. At a setting higher
than the ambient temperature, the burner should ignite.
4.4 Check the pre-pressure
The gas pre-pressure must be measured at the gas unit when the appliance is in operation. The pre-
pressure is indicated on the appliance’s type plate. To check, the volume of gas consumed [3] can be
measured via the gas meter (temporarily switch off all other appliances that consume gas).
4.5 Check appliance operation.
Finally, check that the operation of the appliance cannot be inuenced by other appliances close to
it, localised air ows or corrosive or explosive vapours, etc.
4.6 Set the gas control unit [6]
Before being packed, each appliance is fully tested for safety and correct operation. The correct
combustion values are set during this procedure. If checks indicate that the CO2 value is different
from that in table [3], adjustments may be made (difference of more than 0.2%). Never adjust set
screws without the correct measuring equipment.
