User manual WHIRLPOOL AGB 461/WP INSTRUCTION FOR USE

[. . . ] The appliance is also fitted with a stainless steel fat tray. The plate is heated by tubular chromium-plated steel burners, built to withstand thermomechanical stress. The combustion chamber and flues are made of electrogalvanised steel sheeting. The temperature may be adjusted through special cocks with thermostats, complete with safety devices. [. . . ] The correct volume will be the value of “E” expressed in litres per hour (It/hr) or litres per minute (It/min). The following formula is used to calculate the value of “E”: Testing the power rating Use the specific nozzles for the nominal capacity on the appliance. Capacity can be of two types: - nominal, as given on the data plate; - minimum. These nozzles are shown in “TECHNICAL DATE” table 1. The following are the operating pressure tolerances to obtain the nominal power according to the agreed nozzles: - from 15 to 22. 5 mbar for gases of the second family - from 25 to 35 mbar for gases of the third family (propane). The appliance will not work outside the above pressure threshholds. To adjust the capacity to its minimum value, use the data in tables 1. If you wish to check the nominal capacity further, you may do so using a gas meter according to the so-called ”volumetric method”. E= Capacity Heat value Capacity should only be measured when the appliance is at a standstill. The heat value can be obtained from your local Gas Board. To obtain the nominal and minimum capacities in relation to the nominal pressure, consult table 1. WARNING It is not possible to adjust nominal capacity in advance. Checking power rating when using LP gas Check that the type of nozzles used match manufacturer's specifications. Check that the output pressure regulator installed collaterally to the plant conforms to the specifications laid down in paragraph "Testing the power rating" (see data plate or measure the pressure) page 8. 3 21 1 Smooth, grooved and chrome-plated plates with THERMOSTATIC VALVE 22 16 17 014- 03 - Gas fry-top 8 Checking the pilot light When correctly adjusted, the pilot light flame will completely surround the thermocouple and will not flicker; if it does, make sure that the nozzle is the correct one for the type of gas used. rent types of gas, marked in 100ths of mm, are in a case supplied with the appliance (the pilot burner nozzles are marked with a code number). When the appliance has been transformed or adapted, recheck its functions as described in paragraph "Checking the functions". Checking the primary air The plates, whether smooth or grooved, can be adjusted. The air flow is correctly adjusted when there is adequate protection against the flame rising when the burner is cold or flareback when it is hot. Replacing the main burner nozzle To change nozzle (30), pull out the fat tray and loosen the fixing screws holding the control panel in place. Unscrew the nozzle from the nozzle holder with an adjustable spanner; replace with a new nozzle (see “TECHNICAL DATA” table). To make changing the nozzle easier, loosen screw (39) to push the air adjustment sleeve back. To replace the following parts, first remove the control knobs, slide out the fat tray and remove the control panel (after unscrewing its fixing screws). MAINTENANCE The following maintenance programme should be carried out at least once a year: - Check that all the safety and setting devices are working properly; - Check that the burners are working properly with regard to: - ignition - combustion safety; - Check the functions of the appliance as described in paragraph "Checking the functions" page 8. If the main burner needs cleaning, proceed as follows: a) remove the control knobs and the fat tray; unscrew the fixing screws and remove the control panel; b) unscrew hose clamp (28, Fig. 2) to disconnect the gas vent connector from the nozzle holder; c) unscrew the fixing screws and remove the front panel of the combustion chamber; then loosen the burner fixing screws. The main burner can now be removed for cleaning. Take care when cleaning the flame apertures. Make sure you use a prong with the right diameter. When reassembling the burner, make sure the back slots properly into the combustion chamber. [. . . ] Do not use steel wool anywhere but on the grilling plate since this might cause rust. For the same reason, avoid touching the appliance with anything made of iron. Do not clean any parts of the appliance other than the grilling plate with emery or sandpaper. If absolutely necessary, you may use powdered pumice stone. [. . . ]
