DRT63ST-B Power-Vent Direct-Vent Fireplaces
COMMONWEALTH OF MASSACHUSETTS
REQUIREMENTS
These appliances are approved for installation in
the US state of Massachusetts if the following
additional requirements are met:
• Install this appliance in accordance with
Massachusetts Rules and Regulations 248
C.M.R. Sections 4.00 through 8.00.
• Installation and repair must be done by a
plumber or gas fitter licensed in the Com-
monwealth 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.

COLD CLIMATE INSULATION

For cold climate installations, seal all cracks
around the appliance with noncombustible
material and wherever cold air could enter the
room. If the floor is above ground level, it is
especially important to insulate outside chase
cavity between studs and under the floor on
which the appliance rests. 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 under-
neath to prevent cold transfer to the fireplace
and into the room. It also helps to sheetrock
inside surfaces and tape for maximum air
tightness and caulk firestops.
MANUFACTURED HOME
REQUIREMENTS
This appliance may be installed in an aftermar-
ket, permanently located, manufactured home
and must be installed in accordance with the
manufacturer's instructions.
Cet appareil peut être installé cómme
du matéri-el d'origine dans une maison
préfabriquée (É.U. seulement) ou mobile
et doit être installé selon les instructions
du fabricant.
This appliance is only for use with the type
of gas indicated on the rating plate. This ap-
pliance is not convertible for use with other
gases, unless a certified kit is used.
Cet appareil doit être utilisé uniquement
avec le type de gaz indiqué sur la plaque
signalétique. Cet appareil ne peut être con-
verti à d'autres gaz, sauf si une trousse de
conversion est utilisée.
CAUTION: Ensure that the cross members
are not cut or weakened during installation.
The structural integrity of the manufactured
home floor, wall, and ceiling / roof must be
maintained.
CAUTION: This appliance must be grounded
to the chassis of the manufactured home
in accordance with local codes or in the
absence of local codes, with the National
Electrical Code ANSI / NFPA 70 - latest edi-
tion or the Canadian Electrical Code CSA
C22.1 - latest edition.

LOCATION

In selecting the location, the aesthetic and
functional use of the appliance are primary
concerns; however, vent system routing to the
exterior and access to the fuel supply are also
important.
CAUTION: Due to high temperatures, the ap-
pliance should be located out of traffic and
away from furniture and draperies (Figure 2).
AVERTISSEMENT : En raison des tem-
pératures élevées, l'appareil devrait
être installé dans un endroit où il y a peu
de circulation et loin du mobilier et des
tentures (Figure 2).
The location also should 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 above the fireplace. Utility shelves like
these are commonly used for locating television
sets and decorative plants.
The minimum height from the base of the appli-
ance to the underside of combustible materials
used to construct a utility shelf in this fashion
is shown in Figure 7 on Page 11.
Be aware that this is a heat-producing ap-
pliance. Objects placed above the unit are
exposed to elevated temperatures.
NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
