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.
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.
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.
