Top it up, if need Do not drain the installation, except in cases of absolute be, avoiding the abrupt input of cold water into the hot boiler. If this necessity. - Page 21 4. Maintenance 4.2.1 Sweeping the boiler Manual sweeping Disconnect the burner cable. Unscrew the 2 flanged nuts with flat washers. Open the door of the combustion chamber. - Remove the baffle plates (number variable depending on the boiler model). - Carefully sweep the flue ways with the brush supplied for that purpose.

Page 22: Chemical Sweeping
4. Maintenance Chemical sweeping A. General principle Boilers are traidtionally swept mechanically. There are now chemical sweeping methods which facilitate this maintenance work. A chemical reagent is applied to the boiler's heating surfaces. After application, the reaction is completed by igniting the burner. The initial deposits are neutralised and pyrolised. -
Page 23: Burner
4. Maintenance E. Cleaning - Remove the baffle plates (number variable depending on the boiler model). - Light sweeping will remove the pulverent residues remaining after combustion. The remaining pulverent residues are easy to remove by sweeping or vacuum cleaning. For certain products, brief application after cleaning has a preventive effect, limiting deposits on the heating surfaces. -
