FUEL BED LAYOUT (continued) 3. Locate the two front coal sections marked ‘L’ and ‘R’ into the slot along the front of the burner tray as shown. The legs of the coals have a slightly tapered front face which is intended to give a tight interference fit into the tray.
SERVICING The fire and flue should be checked on an annual basis to ensure all of the product of combustion are entering the flue and that there is no excessive build up of soot. The frequency of service will depend on usage, but MUST be carried out at least once annually. Servicing must be carried out by a competent person, such as a CORGI registered installer.
