FINISHING YOUR FIREPLACE

Wall board (Gypsum board, sheet rock, drywall, etc.) may make direct contact with sides and top of the fireplace face. It is important that combustible materials do not overlap the face itself.

Brick, glass, tile or other noncombustible materials may overlap the front face, provided they do not obstruct essential openings like louvered slots or any other openings. When overlapping with noncombustible facing material, use only noncombustible mortar or adhesive.

CAUTION: Do not cover up the face louvers top and bottom.

ASH DISPOSAL

Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be placed on a noncombustible floor or on the ground, well away from all combustible materials, pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all cinders have thoroughly cooled.

WARNING: Risk of fire; Replace grate only with DESA International Model 42E GR grate only.

FUEL: Use seasoned hardwood or if a vent-free or decorative gas appliance is installed, burn Propane or Natural Gas only.
