In case of operation indoors, adequate ventilation and gas venting must be assured. Sometimes a chimney is necessary to remove the exhaustsfrom the pressure cleaner. This problem hasn’t to be faced when the ma- chine operates outdoor, but when it’s installed indoor, the following recommendations must be followed: - The chimney path must be always in ascent, straight vertical if possible, and preferably not exceeding a 5 m lenght. - The exit of the chimney must be sheltered to avoid the dripping of rain and to allow the exaust ow. - The chimney section A must be 3 times the outlet chimney of the machine B and at distan- ce of at least 20 cm. It must be underlined that the above recom- mendations are extremely important to pre- vent the condensate from back dripping into the machine. The exausts contain sulphuric acid, condensating at a temperature of ap- proximately 180° C. The condensation shall be avoid, but in any case the condensate from chimney shall not enter the machine. The non observance of these recommenda- tions may lead to the damage of the machine. CHIMNEY SECTION: 3 times the area of chimney Chimney pipe diameter = 150 mm
