Instructions for installation

Installation drawings

Installation

• Before installing the product, verify that the type of gas (natural or propane) agrees with the specifications on the naming plate, which is located at the rear part of the unit.
• If a gas cylinder is used, please choose according to the local standard. The max diameter is 40cm, the max length is 1.2 meters. Put it in a dry, cool position.
• The appliance can be installed as a countertop type. Also, you can dismantle the 4 legs, and then screw the body to the cabinet, but first you should have a matched cabinet.
• The appliance should be both installed and serviced in accordance with all applicable regulations and standards in force.
• The appliance should be connected to a potable water supply in accordance with national regulations.
• Installing the appliance should be in accordance with EN1717 and national water regulations in force.
• The appliance is not suitable for built-in installation. Because the appliance will be working without enough oxygen supplying due to the restricted space, and the combustion products cannot be discharged from the kitchen immediately and completely, which is very harmful to the operators’ health.
• The appliance cannot be installed on an inflammable floor or other combustible objects. If the appliance is installed with its sides next to the walls, please keep a minimum clearance of 10cm away from the walls.
• The appliance should be installed in a well-ventilated area, if possible under a vent hood, in compliance with all applicable regulations in force. This will ensure that all burnt gases produced during the combustion process are completely exhausted.
• Prior to installation, remove all packaging materials from the appliance. Certain parts are wrapped up in adhesive film, which should be carefully removed. Remove any glue traces left on the appliance thoroughly using non-flammable solvents. It is forbidden to use abrasive substances.
• Check that the appliance is pre-set to use the gas family available at the place of installation. Make sure the supply gas is the same as the gas that the appliance allows us.
• If the available gas is different from the gas that the appliance requires to use, please don’t connect it, and mark the gas pipe with a yellow colour mark.
• The appliance should be connected to the gas supply by means of metal pipes –either rigid or flexible– having an adequate diameter. Any flexible hose or tubing that may be used for supplying gas can not exceed 1.5m
• The used gas supply tube or hose shall comply with the national requirement in form. The user should examine the gas tube periodically. If necessary, replace the tube or hose in time.
• When joining pipe fittings, never use oakum or Teflon, as their residues could get to the valve and jeopardise its operation. Instead, interpose a seal gasket suitable for use in gas systems. Do not forget to fit a shutoff valve on the gas supply line upstream of the appliance, which should be closed whenever the appliance is not in operation.
• A 3/4″ male BSP line for the gas connection is located near the lower right rear corner of the product. The serial plate indicates the type of gas the unit is equipped to burn (natural gas or propane). The product should be connected ONLY to the type of gas for which it is equipped.
• An adequate gas supply is imperative. Undersized or low-pressure lines will restrict the volume of gas necessary for satisfactory performance. A combination gas valve and pressure regulator, which is provided with each unit, is set to maintain a 2.0kPa manifold pressure for natural gas or a 2.75kPa/3.7kPa/5.0kPa manifold pressure for propane gas. Fluctuations of more than 25% on natural gas or10% on propane gas will create problems and affect burner operating characteristics.
• The available gas pressure should be the same as that indicated on the naming plate. If the gas pipe pressure is higher or lower than the rated pressure by 15%, please install a pressure regulator to adjust the gas pressure.
• After connecting the appliance to the gas system, check for leaks at joints and pipe fittings; to do so, use soapy water or a specific leak detector (spray).
• Checking gas supply pressure after installation. Gas supply pressure can be measured with a liquid-filled pressure gauge (for example, a U-shaped pressure gauge, minimum scale division 0.1 mbar) or a digital gauge. Procedure as follows:

1. Remove the panel, unscrew the screw on the pressure port (picture 2)
2. Place the pressure gauge.
3. Start up the appliance by following the instructions in the user’s manual.
4. Check supply pressure.
5. After the check, remove the pressure gauge.
6. Replace the sealing screw

The appliance can not be used empty. Ensure to fill water before the operation.

The rear side of the vessel carries a permanently punched mark indicating the maximum and minimum operating level of filling. Fill Water till the level is between the maximum and minimum marks. If the water is below the minimum mark, fill the water.

Ignition

• Prior to lighting, check all joints in the gas supply line for leaks. Use a soap and water solution. Do not use an open flame.
• After piping has been checked for leaks, fully purge the gas pipes to remove air.
• Rotate the knob counter-clockwise; make sure the mark on the knob is pointing to position 0.
• Then push the knob, and press the impulse ignition device at the same time. (picture 6) ( It may take several times to ignite the flame, because there will be air in the pipe, only after air comes out, then gas flows in, and ignition can work.)
• When the pilot flame is ignited, after 20 seconds, please release your hand from the knob.
• Rotate the control knob to the position , the burner is operating at maximum power.
• Rotate the control knob to the position , the burner is operating at minimum power.

Extinguish fire.

• Switch off the knob.
• Shut off the gas valve to cut off the gas supply to the burner.

Replace the main burner nozzle, adjust the air inlet, and replace the pilot nozzle

Note: Layman is not allowed to replace the nozzle. (picture 5)

Move the base of the nozzle left and right to adjust the primary air

Adjust the orifice to the desired position. In the picture below, you can find the suggested position. The distance is between the burner base and the orifice.

Replace the nozzle of the main burner

• Prepare one Phillips screwdriver and two proper open spanners
• Dismantle the control panel, and then remove the nut and aluminium pipe, dismantle the joint of the nozzle, unscrew the jam nut, remove the nozzle and replace a new proper nozzle.
• Screw the two jam nuts, and fit all the dismantled parts again. Finally, fit the control panel.

Replace the pilot nozzle

Use a proper spanner on the nut of the nozzle to balance the torsional stress. Then unscrew the screw of the thermocouple and the aluminium pipe, and dismantle the thermocouple and the aluminium pipe. Remove the pilot nozzle, and then replace a new proper one. There is no need to adjust the primary air.
