Burner and Burner Compartment
It is important to keep the burner and the burner com- partment clean. At least once per year the logs and lava rock/ember material should be removed and the burner compartment vacuumed and wiped out. Remove and replace the logs as per the instructions in this manual.
Always handle the logs with care as they are fragile and may also be hot if the fire- place has been in use.
FK24/FK12 Fan Assembly
The fan unit requires periodic cleaning. At least once per month in the operating season, open the lower lou- vre panels and wipe or vacuum the area around the fan to remove any build up of dust or lint.
Brass Trim
Clean the brass trim pieces using a soft cloth lightly dampened with lemon oil. Do not use water or house- hold cleaners on any brass components.
Contact your local representative to arrange an annual service program.
