Carefully position the ceramic fiber logs and twigs over the burner as shown in Figures 7 (MPD- 3328), 8 (MPD-3530) or 9 (MPD-4035, MPD-4540).For more detailed placement instructions, refer to the LOG PLACEMENT GUIDE accompanying this document.

Proper twig placement is critical to prevent sooting. Twigs should be placed in the gaps between the flame peaks and should be positioned so that at no time they impinge the flames.
