9.1 Principle of ignition cycle
Below you will find a brief description of how this appliance is ignited. The appliance is off and will be switched on by
means of the remote control. The receiver in the appliance will get a signal from the remote control to start the ignition
process. This signal is passed on to the burner device, after which, if applicable, the relay for the Powervent System
®
is
switched. After an 8 second interval, the ignition on the spark electrodes will start. If no Powervent System
®
is connected,
only the relay will switch and the appliance will ignite immediately. The main burner will be ignited at about 50% of its
capacity. This will prevent a larger amount of gas in the combustion chamber, if no ignition takes place. When the gas
ignites, ionization will have to be detected. In order to make sure the flame has passed over, this will take place at the
other side of the burner. When ionization is detected, the gas control will modulate to 100%. In the case of a switchable
second burner, the second valve is switched after this (you will be able to hear a 'click') in order to ignite the second
burner. After ignition of the second burner, the appliance will always go to full output (full capacity). This will guarantee
that the second burner will actually ignite. The second burner can be switched on and off manually, by means of the
remote control. In case of switching on manually, the appliance will first return to full load.

The control unit of the appliance meets strict safety demands. It is possible that the burning appliance switches off
automatically and then switches back on again. This is not a failure, but a check. The moment the appliance's control unit
is connected to mains voltage, the control unit will perform this check every 24 hours. If the appliance is burning at that
time, the appliance will extinguish and then start again immediately. This can be prevented by removing the plug from
the socket and immediately inserting it again at a time when the appliance is never or hardly ever burning.
9.2 Connecting the switch contact
(if applicable)
It is possible to operate one or more lamps (in case of several lamps, a maximum of 0,5A/250VAC/30VDC) via the remote
control of the appliance. You could think of the lamps of Dru's lux elements. For this, you can use switch contact B on the
receiver (see fig. 9-2). If the appliance is provided with LED lighting, switch contact ‘B’ is cancelled. The switch contact is
not polar sensitive.
