Overview Overview General information The installation of an oil-fired system must conform to extensive regulations and requirements. It is there- fore the duty of the installer to be familiar with all applicable regulations and requirements. Installation, star- tup and maintenance must be performed with utmost care. Fuel oil type EL to DIN 51603 must be used. The burner must not be operated in rooms with high levels of air humidity (laundry rooms), dust or corrosive vapours.
Overview Maintenance and customer service The complete system should be checked once a year for correct functioning and leaks by a representative of the manufacturer or other suitably qualified person. We accept no liability for consequential damage in cases of incorrect installation or repair, the fitting of non- genuine parts or where the equipment has been used for purposes for which it was not intended.
Installation Installation Installing flange and burner When installing the sliding flange, only tighten screws 1 and 2 otherwise it will not be possible to secure the burner pipe with screw 3. Slide in the burner, adjust to furnace depth and tighten the screws in the following sequence: 3, 4, 5, raising the housing in the process.
Installation Single pipe system H [m] throughput [mm] [kg/h] bis 2,5 2,5-5,0 5,0-10,0 10,0-23,0 For pure single-pipe operation the bypass stopper must be unscrewed out of the return line opening and the return line opening must be sealed with a gasket and metal stopper.

Function No burner operation LED OFF No heating request Pre-ventilation LED flashing No flame present Burner operation LED continuously on Flame present For maintenance, clean the inspection glass of the KLC 2002 with a clean, lint-free cloth. Never use burner cleaning sprays.
Function Servomotor (version -Z-L, -ZS-L, 2-stage with automatic economy device) The air valve positioning motor adjusts the air valve position or trips the solenoid valve on two-stage burners with air shutoff. Adjustment is via limit switch cams on the positioning drive roller. You can refer to the presetting table for the cam positi- ons for adaptation of the burner to the requisite boiler output.
Function Version B (time meter) Time meters are for the purpose of exact acquisition of the burner runtime and are best connected in parallel with solenoid valve Y6. The time meter is available as an accessory part both directly with the burner and as a retrofit kit.

Service instructions/dimensions Service instructions/dimensions Boiler/burner conditioning Precise boiler/burner conditioning is necessary for low-emission and energy-saving combustion. For this purpose a burner is assigned to the boiler in accordance with the working ranges (Page 28) and in consi- deration of the resistance at the heating gas face. The insertion depth of the burner tube is optimally adju- sted by way of the sliding flange to the relevant combustion chamber.
