7. When a furnace is installed so that supply ducts
carry air circulated by the furnace to areas outside
the space containing the furnace, the return air
shall also be handled by a duct(s) sealed to the fur-
nace casing and terminating outside the space con-
taining the furnace.
8. A gas-fired furnace for installation in a residential
garage must be installed as specified in "Location
and Clearances" section of these instructions.
9. The furnace may be used for temporary heating of
buildings or structures under construction only
when the following conditions have been met:
a. The furnace venting system must be complete
and installed per manufacturers instructions.
b. The furnace is controlled only by a room Com-
fort Control (no field jumpers).
c.
The furnace return air duct must be complete
and sealed to the furnace.
d. The furnace input rate and temperature rise
must be verified to be within nameplate mark-
ing.
e. 100% of the furnace combustion air require-
ment must come from outside the structure.
f.
The Furnace return air temperature range is
between 55
0
and 80
g. Clean the Furnace, duct work, and components
upon substantial completion of the construction
process, and verify Furnace operating condition
including ignition, input rate, temperature rise
and venting, according to the manufacturer's
instructions.
h. An external field supplied air filter must be
used during construction.
10. This product must be gas piped by a Licensed
Plumber or Gas Fitter in the Commonwealth of
Massachusetts.
LOCATION AND CLEARANCES
The location of the furnace is normally selected by
the architect, the builder, or the installer. However,
before the furnace is moved into place, be sure to
consider the following requirements:
1. Is the location selected as near the chimney or
vent and as centralized for heat distribution as
practical?
2. Do all clearances between the furnace and
enclosure equal or exceed the minimums stated in
Clearance Table on the Outline Drawings on pages 4
and 5?
3. Is there sufficient space for servicing the furnace
and other equipment? A minimum of 24 inches front
accessibility to the furnace must be provided. Any
access door or panel must permit removal of the
largest component.
6
0
Fahrenheit.
4. Are there at least 3 inches of clearance between
the furnace combustion air openings in the front
panel and any closed panel or door provided?
5. Are the ventilation and combustion air openings
large enough and will they remain unobstructed? If
outside air is used, are the openings at least 12"
above the highest expected snow accumulation level
(18" minimum for Canadian applications)?
6. Allow sufficient height in supply plenum above the
furnace to provide for cooling coil installation, if the
cooling coil is not installed at the time of this furnace
installation.
7. A furnace shall be installed so electrical
components are protected from water.
8. If the furnace is installed in a residential garage,
it must be installed so that the burners, and the
ignition source are located not less than 18 inches
above the floor and the furnace must be located or
protected to avoid physical damage from vehicles.
GENERAL INSTALLATION INSTRUCTIONS
The manufacturer assumes no responsibility for equip-
ment installed in violation of any code or regulation.
It is recommended that Manual J of the Air Condition-
ing Contractors Association (ACCA) or A.R.I. 230 be
followed in estimating heating requirements. When
estimating heating requirements for installation at
Altitudes above 2000 ft., remember the gas input must
be reduced (See GAS INPUT ADJUSTMENT).
Material in this shipment has been inspected at
the factory and released to the transportation
agency without known damage. Inspect exterior
of carton for evidence of rough handling in ship-
ment. Unpack carefully after moving equipment
to approximate location. If damage to contents is
found, report the damage immediately to the
delivering agency.
Codes and local utility requirements governing the
installation of gas fired equipment, wiring, plumbing,
and flue connections must be adhered to. In the ab-
sence of local codes, the installation must conform with
latest edition of the National Fuel Gas Code ANSI
Z223.1 • National Installation Code, CAN/CGA B149.1.
The latest code may be obtained from the American Gas
Association Laboratories, 400 N. Capitol St. NW, Wash-
ington D.C. 20001.

These furnaces have been classified as CATEGORY IV
furnaces in accordance with latest edition of ANSI
Z21.47 standards • CAN/CGA 2.3. Category IV furnaces
operate with positive vent static pressure and with a
flue loss less than 17 percent. These conditions require
special venting systems, which must be gas tight and
water tight. These Category IV Direct Vent furnaces
are not approved for installation in Manufactured/
Mobile housing.
