STEP 1 -Positioning the firebox
This fireplace may be placed on a combustible or
non-combustible continuous, flat surface. Slide the
unit into position and level the fireplace from side-to-
side and front-to-back. Shim with non-combustible
material, such as sheet metal, as necessary.
Secure the fireplace by bending out the nailing
flanges located on each side of the fireplace and
nailing the unit to the framing. See Figure 4.
STEP 2 -Termination
Two types of termination are available for this appli-
ance, horizontal and vertical. For vertical termina-
tion, skip section A and advance to section B on
page 11.

F. FINISHING MATERIALS
Only non-combustible materials may be used to
cover the black fireplace front.
Combustible Finishing Material. Material made
of or surfaced with wood, compressed paper, plant
fibers, plastics, or any material capable of igniting
and burning, whether flame proofed or not, plas-
tered or unplastered.
Non-combustible Finishing Material. Material
which will not ignite and burn. Such materials are
those consisting entirely of steel, iron, brick, tile,
concrete, slate, glass or plasters, or combination
thereof, or have UL Fire rating of Zero (0).
High Temperature Sealant Material. Sealants
that will withstand high temperatures; General
Electric RTV1O3 (Black), or equivalent. Rutland,
Inc. Fireplace Mortar #63, or equivalent.
After completing the framing and applying the fin-
ishing material (dry wall) over the framing, a non-
combustible sealant, one-half inch wide maximum,
must be used to close off any gaps at the top and
sides between the fireplace and facing to prevent
cold air leaks. See Figure 3.
