MANTELS, SURROUNDS & TRIM INSTALLATION
WITHOUT HOOD
WITH HOOD
Note:
The stated installation clearances provide the safest distance for combustible materials to ensure that walls, ceil-
ings, and mantle components will not be affected by heat discoloration, warping, or possible fire. Each appliance installa-
tion presents a different set of variables which can create problems beyond the control of the gas log manufacturer. It is
the responsibility of the installer to stay within the minimum clearances stated and set forth by the manufacturer within this
instruction manual.
The firebox is shipped with a 2 ¾” hood. Loosen screws and slide the hood into place and tighten screws to hold hood.
Heatmaster, LLC. has an optional 4” hood to replace the standard 2 ¾” hood. Contact your local dealer for details.
NOTE: The hood provided with this firebox must not be modified or replaced with another hood or canopy that is not sup-
plied or approved by HM/AGL, LLC.
The firebox may be finished in an infinite number of ways from rustic to contemporary using marble, stone, wood, brick,
tile or various other natural or man-made materials.
CAUTION:
THE BLACK PAINTED FACE OF THE FIREBOX (EXCLUDING NAIL FLANGES) MUST NOT BE
COVERED WITH COMBUSTIBLE MATERIALS. SOME MAN-MADE BRICKS OR STONES MAY
CONTAIN COMBUSTIBLE MATERIAL.
All noncombustible materials, which overlap the black painted face, must be sealed to the firebox face with a high quality
heat-resistant caulk adhesive or sealant. The edges should also be sealed to act as a fire-stop.
This firebox is a universally listed Ventless Firebox Enclosure. For mantel clearances and noncombustible material re-
quirements when installing a decorative type unvented room heater, see below. The dimensions noted with “min” are the
minimum dimensions that are allowed. Failure to meet the clearance requirements will void your warranty and may result
in a fire hazard.
