BURNER START-UP CYCLE Air-purge: loosen the screw placed on the minimal gas pressure switch mounted on the gas train Screw Plug for pressure measure Pressure switch S7506 AIR PRESSURE SWITCH The air pressure switch setting shall be carried out after having S7507 set all other adjustments of the burner and the air pressure switch shall be at its lowest set-point. -
Page 9: Combustion Head Adjustment
COMBUSTION HEAD ADJUSTMENT Two separate adjustments have to be made: air and gas. These adjustments can be carried out when the burner is still open, during the installation (see page 2 - Fixing to the boiler). Air setting Loosen the two screws 1) and move the internal part of the combustion head 2) so that its rear edge 3) is coincident with the desired set-point on the plate 4). -
Page 10: Combustion Checks
COMBUSTION CHECKS It is advisable to not exceed 10% of CO (gas with calorific value of 8600 kcal/m ), in order to avoid the risk that small changes of the adjustments due, for instance, at draught variation, may cause com- bustion with insufficient air and consequently formation of CO. - Page 11 BURNER STARTING DIFFICULTIES AND THEIR CAUSES Signal Problem Possible cause Recommended remedy 2 blinks Once the pre-purg- 1 - The operation solenoid lets little gas .
