USER MANUAL HG1825AB ASKO

Introduction With this conversion-set you can convert your gas hob from natural gas (G20/ G25) to propane/butane gas. Before you start conversion, check whether your gas hob is genuinely set to natural gas. Tools A. Tube- (or socket spanner 7) B. Screwdriver 4 mm (blade width) C. Torx 20 screwdriver D. Pointed pliers E. Leak spray and/or special pressure gauge F. 7+10 open-end spanner (wok) G. Wok insulation plate Attention: Check the gas tightness after converting the appliance (see chapter 3). Replace the following parts: - injector for the burners - simmer setting screws for the gas taps - sealing rings for the sealing under the burners - screws for fastening the burner head/drip tray on the burner - 3 data labels with the modified gas setting - 3 fibre rings underneath the wok burner screws - Wok burner head (for G110 and G120 only) - Roast burner head (for G110 and G120 only) - Replace appliance regulator with test point adaptor (only for AU and NZ) For verification, you can find the values of the injector figures and simmer setting screws on the stickers of the sets. The characters of the sets (upper case characters for injectors and lower case characters for simmer setting screws) correspond with the characters on the sticker on the base of the lower tray of the appliance. The values are also indicated on the injectors and simmer setting screws. The following sets are possible: - Set ‘A-a’ for simmer burner - Set ‘B-b’ for semi rapid burner - Set ‘C-c’ for rapid burner - ‘G1-g’,’G2’ and ‘G3’ sets for wok burner (‘g’ for simmer setting screw) Example sticker lower tray Examples stickers sets Set ‘A-a’ for simmer burner Set ‘G1-g’ for wok burner

Dismantling (see illustration A) Please note: disconnect the appliance before you remove the drip tray. Prevent damage of the work top. Lay down parts of the appliance on a protected base.

1. Remove the pan supports and the burner heads. Pull up the control

knobs vertically and remove them.

2. Remove the wok burner cup and the wok heads by removing the wok

distributor from the appliance (refer to the manual to do this).

3. Unscrew the burner cups (see illustration A1). For this purpose use a

4. Lift the burner cups vertically upwards.

Attention: remember the position of the burner cups. The sticker in the base layer also indicates the position of the burner cups. A is the simmer burner, B the semi rapid burner, C the rapid burner and E the wok burner. For the domino wok, first remove the appliance from the recess and then remove 3 screws on the left-hand and right-hand sides (see illustration A6).

5. Carefully open the drip tray at the front and slide away the pin of the

grounding clip from the drip tray (see illustration A2).

6. Remove the drip tray/glass plate.

7. Attention! Remember the position of the spark plug holders.

Replace the spark plug holder in the same position during assembly. When necessary, mark the position of the spark plug holders (see illustrations A3 and A4).

Converting (see illustration B) The position, the burner type (upper case character) and the tap (lower case character) are schematically indicated on the sticker in the bottom layer. There are small bags with the corresponding characters in the conversion set (see “Introduction”).

1. Replace the injectors in the burners. Use a tubular spanner 7 for disassembling/assembling the injector

(see illustrations B1, B2 en B3).

2. Replace the simmer setting screws in the taps. The position of the simmer setting screw can vary per type of

gas tap (see illustration B4). Use a screwdriver, blade width 4 mm, for disassembling/assembling of the simmer setting screw (see illustration B5/B6) and when necessary use pliers.

3. On the wok burner, replace the injectors for simmer (G1), wok (G2) and roast (G3). The wok injector is

indicated by one rib on the injector holder, the roast injector by two ribs. The simmer injector is the one in the middle (see illustrations B7 and B8). You can replace the simmer injector with a no. 7 open-end spanner and a 3.6 Nm tightening moment. Use a no. 10 open-end spanner with a 5 Nm tightening moment to replace the roast and wok injectors. For verification, you can find the values of the injectors and simmer setting screws on the data label of this set! For verification also view the values table, injector and simmer setting screws.

4. Place the sticker ‘H1’ in the appropriate block on the current appliance identification card (with the type of

gas/gas pressure) in the bottom tray (see illustrations B9, B10 and B11).

5. Place the sticker ‘H2’ in the appropriate block on the current appliance identification card (with the type of

gas/gas pressure) on the underside of the bottom tray (see illustrations B9, B12 and B13).

6. Place the sticker ‘G2’ in the appropriate block on the current appliance identification card (with the type of

gas/gas pressure) on the back of the user manual (see illustrations B9, B14 and B15). Warning! Check the appliance for gas tightness, especially the injectors and simmer setting screws! Always check for gas tightness before using the appliance! Check the other injectors first before checking the roast injectors. Please note: to do this, connect the appliance to the mains. Do not forget to use the insulation plate!

This labels are examples and could different for other kind of gases.8

Check for gas tightness (see illustration C) Use leak spray to check the gas tightness when the appliance is connected to the gas supply:

1. Seal the injector.

2. Open the gas tap. Attention; press and open taps with thermo electric safety device and keep them pressed!

3. Spray leak spray on the connections and check them for gas tightness (see illustrations C1 and C2).

4. When checking the gas density of the wok or roast injectors, the simmer injector must also be closed off. When

checking the roast injector (wok), connect the appliance to the mains to be able to turn on the solenoid. Position the insulation plate to shield any live parts (switch) (C4). When checking gas density, always leave the roast injector until last. Always use the sealing ring and the control knob. Refer to the manual. Be careful of any live parts. Check the gas tightness with a pressure pump (see illustration C3) when the appliance is not connected to the gas supply:

1. Connect the pressure pump to the gas pipe (see illustration C4) and close all gas taps.

2. Increase the pressure to 150 mbar and close the tap (see illustration C3/10) between the pressure pump and the

pressure gauge (see illustration C3/8). Check the pressure. The maximum pressure loss may amount to 5 mbar per minute. After checking, open the tap (see illustration C3/10) between the pressure pump and the pressure gauge.

3. Open one of the taps and close the corresponding injector (see illustration C5/11).

Attention; press and open taps with thermo electric safety device and keep them pressed!

4. Increase the pressure to 150 mbar and again close the tap between the pressure pump and the pressure gauge.

Check the pressure. The maximum pressure loss may amount to 5 mbar per minute.

5. Repeat this test for all taps and injectors.

You may use an other approved method for checking the gas tightness. Final assembly (see illustrations D)

1. Check the position of the spark plug holders. Incorrectly positioned spark plugs can result in incomplete combustion.

2. Place the drip tray on the appliance. Do not forget to connect the earth cable to the drip tray (see illustration D1)!

3. Place new seal rings in the burner cups (see illustration D2). Screw the burner cups onto the burners with new

4. Position new fibre rings underneath the wok burner screws.

1. Put the knobs, the wok burner cup, the burner heads and the pan supports in position. For G110 and G120,

replace the wok burner head and roast burner head with the burner heads included in the conversion set.

2. Check whether the appliance is connected to the correct type of gas and gas pressure.

3. Open the gas supply and insert the plug into the power socket.

C39 Checking operation (see images E/F) Ignite the burners. Check whether the flame profile is uniform and stable for the complete flexibility ratio (see illustrations E1, E2 en E3). Important for this is that: - The flame does not smother in simmer rate, the burner does not ‘blow off’ at maximum burning (to be recognized in flames that are at a distance from the burner in combination with a ‘hissing’ sound) and there are no long yellow flames. - The burners are positioned correctly (see images F1/F2).
