  1. RESIDENTIAL GAS BURNERS R D B series GOALS: • KEEP STRONG OUR POSITION ON RESIDENTIAL GAS BURNERS • DEDICATED TO OEM’s MARKET AND REPLACEMENT • COMPLETE RANGE OF PERFORMANCES: • EN 676 • LOW NOx • ALL KIND OF GASES G20, G21, G25, LPG (by a KIT) • BOTH CONVENTIONAL FLUE (CF) & BALANCE FLUE (BF)

  2. RESIDENTIAL GAS BURNERS R D B series MAIN FEATURES: AIR FLOW • AIR PASSAGES DESIGNED TO OBTAIN: • SMALL DIMENSIONS, BUT HIGH PRESSURE • LOW NOISE • FINEST SETUP • EASY MATCHING WITH BOILERS • PERFECT BALANCE FLUE

  3. RESIDENTIAL GAS BURNERS R D B series • AIR PASSAGES DESIGNED TO OBTAIN: • SMALL DIMENSIONS, BUT BIG PRESSURE COMPARISON

  9. RESIDENTIAL GAS BURNERS R D B series MAIN COMPONENTS CONTROL BOX LMG 25.33OB27

  10. RESIDENTIAL GAS BURNERS R D B series CONTROL BOX LMG25.33OB27 FEATURES: # El. supply 230 VAC +10 -15%---50-60Hz # Undervoltage AC 160 V # Electrical polarity must be respected # Flame signals: operation reliable value min 2µA at beginning max value 0.5µA

  11. RESIDENTIAL GAS BURNERS R D B series Control program in the event of fault: · If a fault occurs, all outputs will immediately be deactivated (< 1 s) · On restoration of power, a restart will be made with the full program sequence · If the operating voltage drops below the undervoltage threshold, a restart will be made with the full program sequence · If there is a premature faulty flame signalÞ Lockout · If the contact of the air pressure monitor «LP» has welded in the working position, start up will be prevented and, after 65 seconds, lockout initiated · If the contact of the air pressure monitor «LP» has welded in the idle position: lockout at after 52.5 seconds · If the burner does not ignite by the end of safety time Þ Lockout · If flame is lost during operation: Þ Three repetitions Lockout: · Lockout cannot be changed and takes place 10 seconds after safety shutdown. A main voltage failure during that period of time wil lead to a restart. Resetting: · When never lockout occurs, the burner control can immediately be reset. To do this, keep the lockout reset button depressed for a minimum of 0.5 seconds and a maximum of 3 seconds!
