5 1. GENERAL 1.1 Description of the appliance Construction and fitting out of the storage appliance comply with the European Standard for gas fired hot water storage appliances for sanitary use (EN89). The appliance thereby satisfies the requirements of the European Directive for Gas Appliances, and is therefore entitled to bear the CE mark.
6 1.2 Technical safety equipment 1.2.1 Gas control The water heaters are equipped with a gas control valve which regulates the flow of gas to the burner. The combination gas control is equipped with a safety valve, gas control valve, pilot safety valve and burner control (on a standard natural gas setting) 1.

11 I MD- 0065 2 . FOR THE INSTALLER If possible, use a trolley or fork-lift truck to move the water heater. Always move the water heater in an upright position.
12 I MD- 0066 -R0 Depending on the length and insulation of the water piping and the water demand frequency, it may be necessary to install a circulation system on the drain cock. The return pipe of the circulation piping can be fitted on the top of the drain cock after the sealing plug has been removed (see figure 6).
13 I MD- 0059 Depending on the water demand pattern (e.g., small amounts frequently), it may be necessary to circulate the water in the water heater to prevent temperature stratification. Therefore, we recommend that a circulation system is installed in the event of such demand patterns (see figure 8).

19 2. 2 Turning the water heater on 2.2.1 Filling the water heater 1. Assemble the drain-off tap and check that it is closed. 2. Open the cold water tap to the water heater and open a l l taps on hot water outlet points to vent them. The heater is filled as soon as cold water pours out of all outlet points.
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.
21 2. 6 Conversion to another gas Important: Install a gas valve suitable for the type of gas to be used. If the water heater has to function on a gas category (LP or natural gas) other than the gas set as standard (ex works), the water heater must be converted to the applicable gas category with the associated conversion kit(s).
22 2 . 7 Maintenance The water heater must be checked and cleaned regularly (at least once a year) by an accredited installer, so that proper operation is guaranteed. The bar burners, control and safety valves must also be checked. (see figure 17). 2.
23 2.10 Condensation If the water heater has been filled with cold water or if the hot water usage has been very high, normally condensation of the flue gasses will occur on the cold sides of the combustion chamber and the flue tubes. The water drops will fall on to the burner bed which can cause a hissing sound.
24 3 . FOR THE USER 3.1. Instructions for use Installation and commissioning of the water heater should only be undertaken by a registered installer. 3.1.2 Filling the water heater 1. Assemble the drain-off tap and ensure it is closed; 2. Open the cold water tap to the water heater and open a l l taps on hot water drain-off points to vent them.
25 No or insufficient hot water. Check whether the electricity is turned on. Check whether the gas supply is turned on. Does the ON/OFF switch light up? Does the RESET switch light up? Push RESET switch up to three times Is the water heater in operation? Consult your installer.
