CHECKING THE INJECTOR NOZZLE PRESSURE
All appliances are adjusted in the factory to work with natural gas. At the same time, the injector nozzle pressure adjusting screw is
sealed. In the event of a malfunction, the injector nozzle pressure can be checked as follows: (see Fig. 6).
Remove the screw from the injector nozzle pressure measuring nipple (4) and connect the manometer.
Start the appliance and turn the thermostat knob to position 7. The table "TECHNICAL DATA" gives the injector nozzle pressures at
rated pre-pressure. The factory technical staff should be consulted in the event of any deviations or malfunctions. The pressure
adjusting screw seal must under no circumstances be broken, otherwise the guarantee covering the appliance is automatically
forfeited.
THERMOSTAT
The thermostat is preset in the factory. The various positions on the thermostat knob enable you to set the desired temperature.
MAINTENANCE
CHECKING THE CONDITION OF THE BYPASS FLAME INJECTOR NOZZLE

bypass flame pipe.
CHECKING THE CONDITION OF THE MAIN BURNER INJECTOR NOZZLE
The injector nozzles are located in the nozzle holder (B) (fig.5).
Check the disassembled injector nozzles (C) (fig.5) and if necessary, replace by new ones. Check the code number. Reinstall the
injector nozzle with sealing paste.
Checking the Injector Nozzle Pressure
Check the injector nozzle pressure at the highest and lowest settings. (See technical data).
Attention: when the heater is assembled, check the tightness of all gas-conducting elements with soapy water.
