Declaration of conformity in accordance with ISO / IEC 17050-1 Manufacturer: RIELLO S.p.A. Address: Via Pilade Riello, 7 37045 Legnago (VR) Product: Gas burner Model: BS3/M TXL These products are in compliance with the following Technical Standards: EN 676 EN 12100...
BURNER DESCRIPTION One stage gas burner. The burner meets protection level of IP X0D (IP 40), EN 60529. Gas train according to EN 676. The burner is approved for intermittent operation as per Directive EN 676. Note for Switzerland.
2.3 FIRING RATE D11418 Thermal power TEST BOILER The firing rate has been defined according to EN 676 standard. COMMERCIAL BOILERS The burner-boiler matching is assured if the boiler conforms to EN 303 and the combustion chamber dimensions are similar to those shown in the diagram EN 676. For applications where the boiler does not conform to EN 303, or where the combustion chamber is much smaller than the dimensions given in EN 676, please consult the manufacturers.
INSTALLATION The installation of the burner must be carried out by qualified personnel, as indicated in this manual and in compliance with the standards and regulations of the laws in force. WARNING WORKING POSITION The burner is designed for operation in position 1 only. Installation in positions 2, 3, 5, 6 and 7 is not recommended as it is likely to hinder the unit’s proper operation since air damper closure cannot be guaranteed when the burner is on standby.
3.2 BOILER FIXING To fit the burner to the boiler it is necessary to carry out the following: Widen, if necessary, the insulating gasket holes (3, fig. 3). Fix the flange (5) to the boiler door (1) using four screws (4) and (if necessary) the nuts (2) interposing the insulating gasket (3) but keep unloosing one of the two upper screws (4) (see fig.

BURNER START-UP CYCLE Limit thermostat Safety thermostat Motor Servomotor Ignition transformer Valve flame flame D4435 15 25s Min. 30s 2.5s 3s max. MAINTENANCE The burner requires periodic maintenance carried out by a qualified and authorised technician in conform- ity with legislation and local standards. Maintenance is essential for the reliability of the burner, avoiding the excessive consumption of fuel and consequent pollution.
FAULTS / SOLUTIONS The control box has a self-diagnostic system, by which it is possible to easily check the faults and find the solutions. To use this function, wait for a minimum of 10 sec after the lock out, then push the reset button for 3 sec. After releasing the button, the RED LED will begin to flash, as shown in the following schedule.
GENERAL INFORMATION IDENTIFICATION The Identification Plate on the product gives the serial number, model and main technical and performance data. If the Identification Plate is tampered with, removed or missing, the product cannot be clearly identified thus making any installation or maintenance work potentially dangerous. GENERAL WARNINGS The dimension of the boiler’s combustion chamber must respond to specific values, in order to guarantee a combustion with the lowest polluting emissions rate.
ACCESSORIES PC INTERFACE KIT: code 3002719 MULTIBLOC ROTATION KIT There is a special kit available that can be used to install the burner turned 180°, as illustrated on page 5 in position 5 in the section entitled "3.1 WORKING POSITION". This kit is designed to ensure the gas train valve works properly.
