Conditions Of Guarantee - Kroll KG/UB55 Betriebsanleitung

Attention please - A summary of important points regarding "Kroll Multifuel Oil Burner"
1. Read operating instructions carefully, prior to installing and commissioning the heater.
2. The incorrect adjustment of the burner may destroy the combustion chamber and the heat exchanger; therefore, it is
important that the output is correctly set. In order to avoid condensation, the net temperature of the flue gases (=the measured
temperature of the flue gases in °C minus the inlet temperature of the burner in °C minus the inlet temperature of the burner in
°C) must not drop below a value of 160°C (at space heaters).
3. The burner adjustment must be carried out by a specialist (after-sales service for the burner).
The flames must on no account touch the walls of the combustion chamber.
Clean the combustion chamber and the heat exchanger at least once a year. Have the oil burner checked and serviced at
4.
least annually. Conclude a service contract.
5. Do not switch off at the master switch while heating . Use the device switch instead. Otherwise, the device will be destroyed, as
there will be no after-running of the cooling air blower (when using space heaters).
6. Rectify the cause of defect before unlocking the overheat thermostat (warm air thermostat) or the overload relay.
7. In order to qualify for the guarantee, the device must be installed and commissioned by a specialist. The settings are to be
recorded in a measurement certificate.
8. Please fill out all the points of the guarantee form correctly, sign, and send it to Kroll. Please note that in case of missing
measuring values no guarantee certificate will be used.
9. In case of temperatures below 4°C, the oil should be heated in the reservoir (or in the unit tank respectively). (For the relevant
heating cartridges, please refer to the accessories).
In order to protect the control of the heating please note the charging rate of the burner (if necessary, install an
10.
additional relais).
