Has the ceramic core in the burner absorbed liquids other than the right fuel?
Yes » The ceramic core in the burner absorbs other liquids, including water, and does not release this from the core. You should refill the burner again with the right fuel in order to filter the wrong fluids from the stone.
No » Please contact your dealer with the problem. If this cannot be solved via the dealer, please contact Ruby Fires via the service form on the website.
