Cannon Fire Coals
The fire coals / pebbles are present only in appliances that do not have a closed burner section. They serve 2 functions. The first is to allow the heat to be circulated to the room. The second function is safety, they are manufactured to fit together in a specific way that optimises combustion. If the coals or pebbles are assembled incorrectly, toxic gases could escape from the fire due to incomplete combustion. Please read instructions for installation carefully or contact a registered gas safe engineer.
