The Cannon 50 cm CH50GCIW Twin Cavity Gas Cooker in white is a gas conventional oven with a grill combined with the top oven. The grill comes with a grill pan. There are 4 gas hobs. The main oven doors are double glazed to assist with energy conservation. The Cannon 50 cm CH50GCIW Twin Cavity Gas Cooker's main oven cavity capacity is 41 litres & the second oven cavity capacity is 19 litres. The Cannon 50 cm CH50GCIW Twin Cavity Gas Cooker is installed with a safety valve called a flame failure device. The flame failure device cuts off the gas supply within seconds if it senses that the burner isn't lit & there's not much of a point trying to light it once it has already cut off the gas supply. The Cannon 50 cm CH50GCIW Twin Cavity Gas Cooker comes with Minute Minder. The programmable minute minder counts down the remaining cooking time. An audible signal alerts when the food is ready & the oven is turned off, so that the food will not over-cook or burn.
