The discharge/intake vent pipes must have the same diameter of o 80 mm. 2. The maximum combined flue length is 17 m. In this case the minimum length for the air intake pipe is 1 meter; the maximum length of vertical exhaust pipe must be a maximum of 12 m. 3. If an elbow is inserted into the discharge/ventilation system, the calculation of the overall extension must take into consideration the values for each curve, as indicated in the table. 4. The exhaust pipe must extend at least 0.5 m above the ridge of the roof if it is located on a side other than that for the air intake (this is not obligatory if the exhaust and air intake pipes are located on the same side of the building).

Expansion Vessel 3.1 Initial Preparation Preliminary electrical system checks to ensure electrical safety must be carried out by a competent person i.e. polarity, earth continuity, resistance to earth and short circuit. Filling the Heating System: Remove the panels of the case and lower the control panel (see point 3.2. for further information). Open the central heating flow and return cocks supplied with the connection kit. Unscrew the cap on the automatic air release valve one full turn and leave open permanently. Close all air release valves on the central heating system. Gradually open valve(s) at the filling point (filling-loop) connection to the central heating system until water is heard to flow, do not open fully. Open each air release tap starting with the lower point and close it only when clear water, free of air, is visible. Purge the air from the pump by unscrewing anticlockwise the pump plug and also manually rotate the pump shaft in the direction indicated by the pump label to ensure the pump is free. Close the pump plug. Continue filling the system until at least 1 bar registers on the pressure gauge. Inspect the system for water soundness and remedy any leaks discovered. Filling of the D.H.W.System: Close all hot water draw-off taps. Open the cold water inlet cock supplied with the conne...
