Gazco eReflex 135RW 1-2-3 Sided Electric Fire - For purchasing the 3 sided option, can you let me know how i choose this option, or can you choose once received how many sides are "open"

Hi, thank you for your enquiry. You can select how many sides you have "open" upon installation. This product comes with all the glass and blanking plates needed for this to be compatible with any installation choice.
