The grate is part of the basic equipment of the boiler. Can be replaced if worn or injured.
Function: discharge of the ashes generated during the burning process into the ash collecting chamber, as well as the even distribution of the air required for the combustion of the fuel. When inserting it is important that the upper surface (the one facing the combustion chamber) is the flat surface, so that the slots between the webs of the grate can not be blocked! See in the following picture!
