TEST BOILER The working field 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 dimen- sions 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 con- sult the manufacturers. -

3.5 FIXING THE ELECTRICAL WIRING All the electrical wires, which are to be connected to the terminal strip (7, fig. 1, page 1) should pass through the cable grommet (4, fig. 1). All the electrical wires, which are to be connected into the terminal strip must be gripped in the cable clamps (3, fig. -
Page 9: Air Damper Setting
4.3 AIR DAMPER SETTING The regulation of the air-rate is made by adjusting the air damper (1), after loosing the screws (2). When the optimal regulation is reached, screw tight the screws (2). 4.4 COMBUSTION CHECK D5231 It is advisable to not exceed 10% of CO (natural gas) , in order to avoid the risk that small changes of the adjustments due, for instance, at draught variation, may cause combustion with insufficient air and consequently formation of CO. -
