Massachusetts And New York City, NY Re-
quirements
These appliances are approved for installation
in the following USA locations listed in the
following:
Massachusetts:
These fireplaces are approved for installation in
the US state of Massachusetts if the following
additional requirements are met-
• Installation and repair must be done by a
plumber or gas fitter licensed in the Common
-
wealth of Massachusetts.
• The flexible gas line connector used shall not
exceed 36 inches (92 centimeters) in length.
• The individual manual shut-off must be a
T-handle type valve.
Massachusetts Horizontal Vent Requirements
In the Commonwealth of Massachusetts, hori-
zontal terminations installed less than seven
(7) feet above the finished grade must comply
with the following additional requirements:
• A hard wired carbon monoxide detector with
an alarm and battery back-up must be installed
on the floor level where the gas fireplace is
installed. The carbon monoxide detector must
comply with NFPA 720, be ANSI/UL 2034 listed
and be ISA certified.
• A metal or plastic identification plate must
be permanently mounted to the exterior of the
building at a minimum height of eight (8) feet
above grade and be directly in line with the
horizontal termination. The sign must read,
in print size no less than one-half (1/2) inch
in size, GAS VENT DIRECTLY BELOW. KEEP
CLEAR OF ALL OBSTRUCTIONS.
New York City, NY:
These fireplaces are approved for installation in
New York City in the US state of New York.
COLD CLIMATE INSULATION
For cold climate installations, seal all cracks
around the appliance with noncombustible
material and wherever cold air could enter
the room. It is especially important to insulate
outside chase cavity between studs and under
floor on which the appliance rests, if floor is
above ground level. Gas line holes and other
openings should be caulked or stuffed with
unfaced fiberglass insulation. If the fireplace
is being installed on a cement slab, in cold
climates, a sheet of plywood or other raised
platform can be placed underneath to prevent
conducting cold up into the room. It also helps to
sheetrock inside surfaces and tape for maximum
air tightness and caulk firestops.

LOCATION
In selecting the location, the aesthetic and func-
tional use of the appliance are primary concerns.
However, vent system routing to the exterior and
access to the fuel supply are also important.
Consideration should be given to traffic ways,
furniture, draperies, etc., due to elevated surface
temperatures (Figure 4). The location should
also be free of electrical, plumbing or other
heating/air conditioning ducting.
These direct vent appliances are uniquely
suited for installations requiring a utility shelf
positioned directly above the fireplace. Utility
shelves like these are commonly used for locat-
ing television sets and decorative plants. Be
aware that this is a heat producing appliance.
Objects placed above the unit are exposed to
elevated temperatures.
To provide for the lowest possible shelf surface
use the alternate rear vent outlet with attached
venting routed in a way to minimize obstructions
to the use of the space above the appliance.
Do
not insulate the space between the appliance
and the area above it. See Figure 9. The mini-
mum height from the base of the appliance to
the underside of combustible materials used to
construct a utility shelf in this fashion is shown
in the Table in Figure 9.
The appliance should be mounted on a fully
supported base extending the full width and
depth of the unit. The appliance may be located
on or near conventional construction materials.
However, if installed on combustible materials,
such as carpeting, vinyl tile, etc., a metal or
wood barrier covering the entire bottom surface
must be used.
