T Ge Bei User manual RGA60 RGA95 Issue 13 09 elster 10 Fitting Instructions Page 21 Ignition System The ignition system is a vital part of your oil fired air heater Its function is to light the oil coming out of the nozzle and it must be capable of doing so under adverse conditions such as extreme cold It is therefore very important that it is properly adjusted If the ignition system is badly adjusted the ignition spark may form in the wrong place or may not form at all This will cause the heater to lock out If you look in at the front when the removed burner is activated you should be able to see the ignition system come into operation Between the two ignition electrodes a well defined spark should be visible Under the influence of the air current the spark should form in front of the nozzle If you can see a strong spark and it is in the right place the ignition system should function properly If the ignition electrodes should ever need adjusting adjust them very carefully because if the electrodes porcelain sleeving breaks or cracks they will have to be replaced The diagrams below show how the ignition system should be adjusted ia RGA 60 wee RGA 95 00 09 SS LA
