1. TECHNICAL INFORMATIONS 1.01 Introduction GNK1 boiler is a new heating generator with high efficiency, for central heating system as well sanitary hot water production suitable for burners using oil or gas. The boiler body is built by cast iron sections joined togheter by mean of biconical nipples and tie rods.

Summer /Winter switch on the «SUMMER» setting When the switch has been set to this position, the plant will produce hot sanitary water only and the relative heating circuit will be kept permanently off. The burner and circulator will therefore only operate to maintain the temperature of the sanitary water whilst this is being used or during long periods at a standstill.

t s i ∆ N.B.: Max. water temperature for the heating system is 110° C. NOTE: When priority ends with high temperature water in the boiler, the thermal inertia which develops when the circulator stops could inhibit the boiler itself (total switch-off) owing to activation of the safety thermostat at 100˚C.
5 A max must be provided. N.B. - Appliance must be earthed. It is recommended to connect the boiler to a good electric earth system. FERROLI could not be considered responsable for any kind of damage to Persons or things caused by failure of earthing...

4.02 Connection to the water main Connect the appliance to the water main in compliance with the indications near each fitting and those listed in fig. 2 of this handbook. Connections must be made so that the pipes are free from tensions. It is essential to mount the safety valve on the heating circuit and on the sanitary circuit, using the relative fittings in the boiler.

5. TESTING 5.01 Before the first light of the boiler Before the first light of the boiler follow these check list: a) check the system and the boiler is filled with water at the right pressure; b) check against any leakage of water fuel; c) check that the correct electric power is supplied to the unit;...
6.01 Boiler cleaning Cut out electric power. Cut out the panec 1, 2 and 3 (fig. 7). Clean the boiler internal parts. Check the flue duct and if necessary clean it. The burner service must be done according the Manufacture Instructions. 6.02 Boiler cleaning Shut the sanitary water on-off valve at the heater inlet and completely drain the water from the heater itself.
7. OPTIONALS 7.01Programmer clock 1 - Remove plug «A» from the control panel. 2 - Fit clock «B» into its housing. 3 - Fix with screws «C». 4 - Remove the jumper between terminals 11-12 and connect the clock cables as shown in the wiring diagram.

7.02 Programming Turn the program disk in a clockwise direction to set the time just like a normal clock. Lower the mobile rods to select the activation times can be at a frequency of 15 minutes a time (each mobile rod). The lever switch near the pointers enables the following operations: 1 - Set the lever to position «I»...
