Gas oven design and principles of operation
A gas oven is a heat-insulated chamber built into the body of a gas stove or a separate heat-insulated chamber with burners inside.
The oven in the Hephaestus gas stove models currently presented by the industry has two burners - the main burner for cooking traditional dishes and pastries, and a grill burner for baking meat dishes.
The oven is completed with a baking tray, a roaster for collecting juice and fat, a grate for placing baked meat, vegetables, fish on it
The principle of operation of the oven in a gas stove is to heat the air as a result of the combustion of liquefied fuel or natural gas. The supply of gaseous fuel to the burner and combustion chamber is carried out from the network or a gas cylinder.
The TUP valve regulates the gas supply. It, passing through the nozzle and mixing with air, then leaves the nozzle and ignites.
Ignition can be carried out manually, using matches and an electric lighter, or using an electric ignition built into the structure of the gas stove
GEFEST ranges are also equipped with a timer, pleasant lighting in the oven, and a gas control function. This very gas control serves to interrupt the gas supply in the event of its attenuation. The latter function is simply irreplaceable if a weak flame is blown out with a draft or the liquid escaping from the pan floods the fire.
What is a TUP crane and how does it work?
The TUP valve is a thermostatic safety device, which is a capillary tube containing a kerosene mixture. There is a small canister on one side of the tube. When heated, the kerosene liquid expands and covers the gas path to the burner, and when the temperature drops, it opens.
The TUP tap has a start button that opens gas access to the oven burner. There are models in which a tap is installed without a button
The TUP mechanism is hidden behind the stove panel and is controlled by the tap handle, which simultaneously controls the operation of the oven and grill, maintaining the set temperature.
Gas control function in household stoves
Gas control is a useful feature that greatly enhances the safety of gas cooking equipment during operation.
At the same time, it is she who makes it difficult to ignite the stove, and in the event of a breakdown, it makes it completely impossible to use the equipment.
The operation of a gas stove with a faulty and poorly functioning gas control system is unacceptable! If a breakdown is found, you must contact a specialist
Oven taps with built-in gas control in different stove models differ in the number of thermocouples connected to them. Crane with two thermocouples controls the burners of the oven and grill, with one thermocouple - controls and starts only the oven.
Thermocouple on the example of a gas burner. For a thermocouple to work, it must heat up for a certain amount of time. Until it warms up, you need to keep the burner valve pressed so that the valve does not interrupt the gas supply
A thermocouple is two wires of different materials that are fused together in such a way that the junction forms a small ball. When the temperature rises to the set temperature in the working area of the part, a small electrical signal appears.
This weak electrical charge is transferred to the solenoid valve, which then opens the gas path. If the flame goes out, the thermocouple cools down. Due to the temperature drop, the signal ceases to flow to the valve, which closes the blue fuel supply channel.
General rules for connection and operation
Before buying a gas stove with the Hephaestus logo, you should find out how its oven works, what functions and protective systems the equipment is equipped with. It is necessary to check whether its technical parameters and settings correspond to the type and pressure of the gaseous fuel in the network.
Installation and connection of the device is carried out by an employee of the gas industry, with whom contract signed for the supply of blue fuel and maintenance of equipment. Subsequently, he must fill out an installation coupon indicating the nature of the changes in the settings, if any.
Warranty service for gas stoves and household ovens of the Hephaestus brand is carried out by a service technician. Subsequent repairs or adjustments can be performed by specialists who have the appropriate permission to repair gas equipment
Use in an apartment or a country house gas stove requires the owner to strictly adhere to safety rules.
The operation of a gas oven is allowed if:
- the stove is installed in a fireproof place, grounding is carried out;
- the gas stove and, in particular, the oven, are in good order, all structural elements are intact;
- baking sheet and wire rack are not overloaded - permissible weight up to 6 kg;
- the oven door is closed.
The device should only be used for its intended purpose - heating the room, drying of flammable objects is unacceptable. If there is a smell of gas, first of all, the common valve of the fuel supply pipe should be closed, and then all the valves of the burners. Emergency service is called to repair the leak.
How to light an oven or grill on a gas stove?
The gas oven can be ignited using matches, an electric lighter, or an electric igniter. Electric ignition can be semi-automatic, in which, simultaneously with turning the lever, you need to press the electric ignition button, and automatic.
In the second version, the ignition mechanism is built into the knobs and is triggered simultaneously with their turn. The mechanism for igniting oven burners is not present in all gas stoves, but only in models with 6-channel electric ignition.
Using the electric ignition for the oven
To light the main burner with the built-in electric igniter, open the oven and turn the knob of the rotary switch counterclockwise until it stops - to the maximum temperature scale. Then it is necessary to simultaneously press the PU button or the TUP toggle switch and the button of the electric ignition device.
The ignition process lasts no more than 5 seconds. It happens that this time is not enough and the flame extinguishes when the TUP handle is released. In this case, it is necessary to take a break so that the gas dissipates, and try again after 1 minute.
From the moment the burner ignites, it is necessary to hold the button or the TUP lever for 15 seconds - until the fuse is triggered, which will allow gas to flow into the burner. Now it remains to make sure that the combustion of the flame is stable, and set the required temperature regime
For the grill burner, the same ignition principle applies, but the TUP knob is turned clockwise as far as it will go. This is the only and unchangeable position that sets the temperature at a level sufficient for the grill to operate.
After turning the switch, the gas enters the upper burner, a fuse is installed here, which blocks the gas outlet in the event of the flame extinguishing.
How do I light the main burner of the oven manually?
To light the lower burner in the Hephaestus stove using matches or an electric lighter, open the oven door, then press and turn the TUP knob to the 270 ° C mark.
Bring the fire source to the igniter window simultaneously with pressing the PU button or rotary switch knob all the way, keeping it pressed for about 15 s. After making sure that the gas is on, the handle is placed in the required position for use.
After releasing the PU button or the TUP knob, you must make sure that the flame continues to burn. The lower the room temperature, the longer it will take. If the flame still goes out, repeat the ignition.
The temperature regime is selected in accordance with the cooking technology of certain products. General recommendations are shown in the table.
If ignition is successful and the flame is not extinguished, close the oven and leave to warm up. In order for a stable temperature regime to be established in the oven, you must wait at least 5 minutes.
Manual ignition of the top burner-grill
To light the upper burner, open the oven and turn the TUP switch to the "Grill" position. Bring a match or an electric lighter to the upper burner, while simultaneously pressing the TUP knob or the PU button, holding it for 15 seconds.
The upper burner of the oven works only in one mode - the temperature is not regulated. To ensure the food is fried properly, use a skewer that turns at a certain speed, or turn the food by hand
It often happens that the burner does not ignite the first time, therefore, after lighting it up, make sure that the flame is on and only then close the oven. If the burner still goes out, repeat the procedure from the beginning.
Gas burner does not ignite or goes out
The cause of the malfunction associated with turning on the oven and ignition of burners, there may be clogging or wear of parts, failure of the sensor that monitors the state of the flame.
Ways to solve a problematic task can be as follows:
- Faulty (tip misalignment, clogging or wear) thermocouple. Causes insufficient voltage to the solenoid valve. As a result, it shuts off the gas supply to the oven burner. Replacing the part will help fix the problem.
- Breakdown of the solenoid valve. In the event of a malfunction of the gas valve, the control sensor transmits voltage. However, the valve is not kept open - the burner is interrupted as soon as the gas valve is released. The valve must be replaced.
- Clogged nozzle. Prolonged use or product ingress on the nozzle leads to partial or complete blocking of the gas outlet channel. To fix the problem, the burner is removed and cleaned.
- Failure of the TUP crane. The cause of the breakdown may be damage to the rotary mechanism located inside or to one of the links in the gear. The part should be replaced with a new one. If the cause is a clogging of the crane slewing mechanism, it is cleaned.
- Oven decay after heating. A poorly adjusted minimum combustion mode, which the oven switches to after the highest heat, causes a too low flame. The control sensor does not warm up sufficiently and cuts off the gas supply. The master can fix the problem - it is necessary to adjust the burner operation.
Gas ovens are not always equipped with a gas control function, sometimes they do not have an electric ignition. Therefore, the rules of operation, ignition and the reasons for the extinction of the fire must be considered for each model of the gas stove separately.
