The heat deflector is a useful accessory for your Artisan Tandoor. It assists you to prolong the maintained heat in the tandoor, which it enables you to cook for a longer period of time.
The deflector is placed over the red hot coals, which reduces the direct heat generated from the coal and prolongs the time the coal disperses heat across the inner walls.
It will also allow you to cook food closer to the coals without burning the food due to the proximity to the coals.
Remember to use the poker to gently lower the heat deflector above the coals.
