Assemble the drain-off tap and check that it is closed. 2. Open the cold water tap to the water heater and open all taps on hot water outlet points to vent them. The heater is filled as soon as cold water pours out of all outlet points. 3. Close all taps at hot water draining points. The heater is now under water supply pressure. At this pressure, the relief valve if fitted may not release water. 2.2.2 Turning the water heater on 1. Check whether the water heater is filled with water and whether the gas pipe to the water heater is open. 2. Vent the gas pipe by opening the pressure gauge nipple at the inlet side of the gas valve. Close the pressure gauge nipple as soon as the gas pipe has been vented. 3. Turn the temperature control knob fully to the left. 4. Turn on- the supply voltage by turning the main switch. NOTE: if the frost-thermostat is calling for heat the burner automation will immediately start its ignition procedure. 5. Turn the ‘I/O’-switch on the column to the ‘T’ position. The control lamp in the switch will light. 6. Turn the temperature control switch to the desired position, preferably position 3 (approximately 60°C). The burner will ignite; the water heater will now work automatically. 7. Check the standing pressure with a manometer which can be connected to the pressure gauge nipple. Check that the working pressure is set to the correct level (see table page 10). 2.2.3 Setting up the pilot flame The pilot flame has been adjusted in the factory and does not have to be checked. 2.3 Turning the water heater off For short periods: 1. Turn the temperature knob fully to the left and turn the ‘I/O’-switch in the ‘O’-position. For longer periods: 1. Switch off the supply voltage. 2. Close the gas tap in the supply line. 3. Close the water supply tap. 4. If there is danger of frost, drain the water heater. 2.4 Usage/temperature control The water temperature is controlled via the temperature regulator. If the temperature in the water heater falls below the set value, the temperature regulator will call for heat. The burner automation will operate firstly the ventilation fan for its purge cycle, then a spark will ignite the pilot burner. The softlite control then ignites the main burner. The position of the temperature control knob coincides with the following temperatures: Position 1 = app. 40°C Position 2 = app. 50°C Position 3 = app. 60°C Position 4 = app. 70°C At high temperatures, more calcium precipitation is caused in the water heater. Moreover, the standby- losses of the water heater are greater with higher temperatures. It is recommended to set the control- thermostat at approximately 60°C. For reasons of security, the water heater is provided with a high limit and safety thermostats. The high limit thermostat is an extra control set at 80°C and will operate in the event of excess temperature within the water heater. If the safety thermostat operates, the ‘RESET’ button must be pressed after the water has cooled down. The water heater will operate again in the usual manner. 20 Figure 14 - Checking the gas pressures 2.5 Checking the gas pressures The nominal load has been set at the correct value in the factory. A further check of the pressure should be carried out during the commissioning of the unit. A dangerous situation can occur if the following instructions are not followed carefully. Setting the nominal load is possible as there is a burner pressure control. If you wish to adjust the burner pressure the following procedures must be followed: 1. Switch off main power by turning the I/O switch to ‘0’ position. 2. Connect the U-tube manometer to pressure nipple B. 3. Switch on main power and ensure temperature control is calling for heat. 4. Wait until water heater is firing. 5. Check pressure against table on page 10 for relevant gas and adjust at main gas valve. 6. Switch of main power as no. Y. 7. Remove U-tube manometer and close pressure nipple. 8. Switch on main power and test for gas tightness and correct operation, (Figure...
