Placing the Ember Material and Lava Rock

Two separate bags of ember material and one bag of lava rock are shipped with this gas fireplace: The bag labeled Golden Ember (GE-93) is flame colorant material. The bag labeled Glowing Ember (050-721) is standard glowing ember material. To place the ember material:

Remove the trim door by lifting up and away from the unit or if you have an ARCH door, pull away from the unit to release it from the clips on each side.

Remove the glass door from the unit. Refer to glass removal in Step 10.

Cover the top of the burner with a single layer of ember material. NOTE: Do NOT cover burner ports with embers. Then sprinkle GE-93 on top of the burner.

Save the remaining ember materials for use during fireplace servicing.

Place lava rock on burner tray.

Replace the glass door and a front trim door on the unit.
