Inside your stove are thin bricks made of a dense insulator that expands and cools as part of the normal process of using your woodburner or multifuel stove. It is perfectly normal for these bricks to crack over time, and it is safe to continue using the stove.
Do not remove the cracked bricks however as this will make your stove work less efficiently. If the bricks are unable to stay in the stove because of the crack of have crumbed away dramatically, contact us online or give us a call on 014462 671555 and we will organise replacement bricks.
These bricks are not covered by the warranty if they crack within the first year, as your warranty covers the stove body. The main body being defined as the steel outer casing and items fixed immovably to the casing.
