Page 17: Tools Required For Installation
INSTALLATION TOOLS REQUIRED FOR INSTALLATION INSTALLATION INSTRUCTIONS General comments The connections (electrical, flue and hydraulic) must be made in accordance with current standards and regulations. Important recommendations for the correct operation of the appliance The boiler must be installed in a dry and weather-protected room. Make sure to position the appliance so that it is always easily accessible. - Page 18 INSTALLATION Make a slight gradient of 3% to the horizontal flue gas pipes so that the acid condensation water runs towards a condensate collector and does not damage the heating unit. Do not store any flammable or corrosive materials, or paint, solvents, salts, chlorine products or any other detergent products in the vicinity of this appliance.

Page 19: Recommendations For Preventing Corrosion And Scaling
A deaerator (on the boiler flow line) combined with a dirt separator (upstream of the boiler) must be installed according to the manufacturer's instructions. - ACV recommends using additives that keep the oxygen in solution in the water, such as Fernox (www.fernox.com) and Sentinel (www.sentinel-solutions.net) products. - Page 20 INSTALLATION 4. Limit the carbonate concentration in the water - The fill water must be softened if its hardness is higher than 20° fH (11,2° dH). - Check regularly the water hardness and enter the values in the service log. - Water hardness table : Water hardness °fH...
