The RH PETERSON EM1 is a rockwool ember glow material used to restore or enhance the visual ember effect in vented gas log fireplace systems. Supplied in a 6-ounce bag, the material simulates the natural glow of live embers when placed around the burner bed. Over time, embers in gas log systems dull and lose their incandescent appearance. The EM1 provides a straightforward solution: use it as a direct replacement for worn embers or supplement an existing bed to achieve a fuller, more realistic glow. Installation is handled by the homeowner or a gas fireplace service technician.
The EM1 is suited for residential gas log fireplaces equipped with vented burner systems. It is placed loosely around the burner bed to mimic the appearance of natural embers. This material is appropriate for use during routine fireplace servicing, seasonal maintenance, or any time the ember bed requires refreshing. It is not compatible with vent-free or unvented burner systems and must only be used with vented burner configurations.
Designed for use with vented gas log burner systems only. Not rated for vent-free or unvented burner applications.
A licensed gas fireplace technician or qualified service professional should shut off the gas supply and allow the fireplace to cool completely before disturbing the ember bed or burner components. Ember material should be placed loosely around the burner following the log set manufacturer's placement guide. Do not pack or compress the material, as this can interfere with proper flame and ember appearance. Always verify the burner system is vented before using this product.
