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].
3.2 Choiceofbuscable
Selection of the correct type of bus cable is based on the specic model for the country concerned.
When selecting the cable, the values noted in the technical details must be complied with. Bus cables
of the appropriate specications, which are offered in countries with an EIB market, are:
– YCYM Fixed system
EIB specication Dry, damp, wet rooms
In the open air (no direct exposure to sunlight)
Face-t, ush-t, in conduits
– J-Y(st)Y Fixed system
EIB specication Only in interior spaces
Face-t, in conduits
– JH(st)H Halogen-free conduits, remote system
– A-2Y(L)2Y or A-2YF(L)2Y Telephone ground cable, system in the outside area
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.
