Is any maintenance of the gas fireplace required?

When used correctly, the burner requires little maintenance. It is good to carefully remove the stones once a year and to blow through the fireplace with a compressor or to remove all dust and grit with a vacuum cleaner. The gas hose and the rubber ring of the pressure regulator must be checked every year. The gas hose and the rubber ring must be replaced once every 5 years.
The black powder-coated fireplace and lid can be cleaned and rubbed with car wax.
A stainless steel fireplace can be cleaned with a stainless steel cleaner.
Only brush, blow or vacuum the perforated burner. Do not use any water or cleaning agents.
