You might want to check out the pilot (usually located in the broiler), otherwise you have a leak.
Brownies rise in the oven due to the leavening agents, such as baking powder or baking soda, that create gas bubbles in the batter. The heat from the oven causes these gas bubbles to expand, making the brownies rise and become light and fluffy.
The gas valve in an oven controls the flow of gas to the burner, regulating the temperature inside the oven for cooking or baking.

You should preheat a gas oven to 400 degrees Fahrenheit for about 15-20 minutes before baking to ensure even cooking and proper results.
In a gas oven, chemical energy from the natural gas is converted into heat energy through combustion when the gas burns. The heat energy is then transferred to the oven compartment and contents through convection and radiation, allowing for cooking or baking to take place.
The choice between a gas oven and an electric oven depends on personal preference and cooking needs. Gas ovens provide more moisture and better heat distribution for baking, while electric ovens offer more precise temperature control and even heating. Ultimately, both types of ovens can produce excellent results depending on the recipe and cooking technique used.
Baking soda (sodium bicarbonate) will evolve carbon dioxide gas when heated. This gas causes baked goods to rise and become fluffy.
The ingredient in baking soda that causes baked goods to rise in the oven is sodium bicarbonate and alum or cream of tartar. Both alum and cream of tartar are acidic. Cream of tartar is used for alum free powders. Sodium bicarbonate is slightly basic. The reaction between the two chemicals when moistened and heated produces carbon dioxide gas which causes the cake to rise as the bubbles of CO2 gas get trapped in the cake.
Brownies rise during baking due to the leavening agents, such as baking powder or baking soda, that create gas bubbles in the batter. As the brownies heat up in the oven, the gas bubbles expand, causing the brownies to rise and become light and fluffy.
If your gas oven is set to gas mark 6, you should set your electric oven to approximately 200°C (or 400°F). Gas mark 6 typically corresponds to a medium-high heat, which is suitable for baking and roasting. Always check your recipe for specific temperature recommendations, as individual recipes may vary slightly.
Gas ovens and electric ovens should both be set at 325 degrees in order to bake a cake at 325 degrees. The type of oven used does not effect the temperature at which a cake is baked.
To effectively clean a gas oven and remove grease and grime buildup, start by removing the oven racks and soaking them in warm, soapy water. Then, mix a paste of baking soda and water and spread it inside the oven, focusing on areas with grease buildup. Let it sit for a few hours or overnight, then scrub with a sponge or brush. Wipe down the oven with a damp cloth to remove the baking soda residue. Finally, replace the oven racks and turn on the oven for a few minutes to burn off any remaining residue.
