Unless, you have a different heater than the model number you listed in the title heading, it's an electric infrared heater. Not a gas heater.

There has been a problem with the heating elements on this unit. So, if you have your Proof of Purchase, you can return it for repair or replacement, because it''s still under warranty. Consult your Owners Manual/Guide, to find out the process for returning it to the manufacturer.

Hope this helps you.
