1.3 Turning the heater on and off

ATTENTION: WHEN THE UNIT IS WORKING, THE TEMPE- RATURE NEAR THE PEEPHOLE MAY BE HIGH. AVOID CON- TACT AS THERE MAY BE RISK OF BURNS. Preliminary checks and operations

1. Make sure the hot water taps are closed.

2. Open the gas supply cock to the heater, located at the gas connection to the unit.

3. Check that the 1.5 V batteries are properiy installed with the correct polar (+). To

replace the batteries, see (3.4 Replacing the batteries)

4. Also verfy that the batteries are suficientiy charged for heater operation.

1.3.1 Turning the unit on

um the knob to the required water heating level. The unit will begin operating every time hot water is draun. 7 BE > fig. 2 - Tuming the unit on

1.3.2 Turning the unit off

The bumer goes off automatically when hot water is no longer demanded. To use the unit again, no action is required. To completely shut off the unit, place the knob in the () position. Bumer power adjusiment Temperature adjustment Burmer on indication fig. 3 - Tuming the uni off If the water heater will not be used for an extended period of time, close the gas cock supplying the unit. If the unit will be inactive for an extended period of time during the winter, all water should be removed to avoid ice damage.

Use the knob (3 fig. 1) to select the heater power. You may choose between the minimum, maximum, and intermediate positions, depending on the required heating power. If the knob is turned counterclockwise, the unit will operate at maximum power. If the temperature is too high, for example in the summer, or if you need a reduced flow of not very hot water, tum the knob clockwise. This reduces the power, and therefore the gas consumption. In the e position, the unit is tumed of.

1.4.2 Setting the temperature

Turn the water temperature selector clockwise to increase the temperature, or counter- clockwise to decrease it. fig. 4 - Setting the temperature

Once the adjustments described above have been made, the heater is ready to operate automatically. When a hot water tap is opened, an intermittent discharge is generated on the ignition electrode to light the bumer. All electronic models have an ionization electrode built into the bumer to monitor flame presence. f a malfunction or lack of gas causes the heater to tum of, close the hot water tap. Itis then necessary to eliminate the fault or obstacle preventing the gas from reaching the heater, eg. inadvertent closing of he gas cock, empty gas cylinder, etc. To reactivate the heater, close and open the hot water tap. I no hot water is produced after eliminating the cause and opening the hot water tap, repeat the process. Ifthe problem persists, call the technical support center.

For the water supply pressure, necessary for operation (see table of characte- The heater may only be installed by an authorized technician, in accordance with all instructions contained in this manual, standard UNE 26, and local installation and exhaust regulations. ristics). + Make sure the room were the unit is installed meets all the requirements of the Current Regulations. In particular, this unit is an “open chamber” type and must only be installed and operate in permanentiy ventilated places. An insufficient supply of combustion air will compromise normal operation and the evacuation offumes. Also, the fumes forming under these conditions are extremely harmful to health if dispersed in the domestic environment. OTHERWISE THERE MAY BE RISK OF SUFFOCATION AND INTOXICATION OR EXPLOSIONS AND FIRE. Therefore the place of installation must be free of dust, flammable materials or objects or corrosive gases. Position the water healer as close as possible lo the hot water taps, near the sink, but NEVER above a cooktop. lt must also be situated as close as possible to the flue or the Start of the flue gas exhaust pipe Ifthe unit is installed inside a cabinet or joined laterally to other elements, space must be allowed for removing the casing and performing normal maintenance activiti

2.4 Hydraulic connections

Never support the water heater by the water/gas connections. Make VAN the connections in accordance with {he dimensions and connections shoun in section 4.1. There are labels on the unit identifing the 1/2 water inlet pipe (white) and the 3/4" gas inlet pipe (yellow). fig. 7 - Connection cards I the water hardness is over 25%Fr ( 1°F=10ppm CaCOS), the water must be treated to avoid possible deposits on the unit.

Before making the connection, check that the unit has been prepared to operate withthe right type of fuel, and carefuly cleanthe gas pipes to remove any residue that might hinder correct operation. Make this connection in accordance with the dimensions and connections in section 4.1. 1-Comnect the corresponding gas inlet (see section 4.2) in accordance with current regulations in the country where the heater is being installed. 2-Connect using a rigid metal pipe (connection to a gas supply network) or a flexible, continuous stainless steel pipe (LPG installation), adding a shut-of valve between the installation and the unit (AS CLOSE TO THE UNIT AS POSSIBLE). 3-Once the connection to the gas network is complete, check that all gas connections are fight. For this purpose, a tighiness test must be performed. To avoid damage to the unit due to excess pressure, leave the gas inlet valve closed. 4-Check that the supplied pressure and gas delivery values are those indicated for the units consumption. See the technical data table (section 4.5). In installations with an approved flexible pipe for LPG, pay special VAN attention to the following: The pipe must comply with applicable regulations. Avoid areas with heat emissions. Prevent the pipe from bending or being pinched shut. The connections on both sides (gas valve and other components) must comply with the regulations of the country where the heater is installed.

2.6 Air and flue gas ducts

The diameter of the pipe connecting to the flue must not be smaller than that of the pipe connecting to the draft hood. After the draft hood, there must be a vertical segment at least half a meter long. The dimensions and installation of the flues and the tube connecting to them must comply with current standards.
