WARNit^G: This furnace is .not water tight and is not
designed for ;outdo6r;installation- This furnace shall be
installed in such a tnanper -as to protect- electrical cotn-

CAUTION; For an attic installation, it is important to

keep insulation 12 in. or more away from any fiimace

A

openings. Some types of insulating materials may be
combustible.

This frrnace is approved for reduced clearances to combustible
construction, therefore, it may be installed in a closet, alcove,‘'or'
similar enclosure. It is also approved for attic installation. As this
unit may be installed as a downflow or'horizontarfurhace,' it >may
be located in a basement, on the same level as area to be Eeated,­suspended, or in a crawlspace. In any case,-.unit should always^be

In unconfíned spaces ijj.buildlnga of conventional frame, brick,-.or
Stone construction, infíltration MAY be adequate to provide air for
combustion, ventilation, and dilution of flue gases. This determi­nation must be made on an individual jnstallaUon basis and must
take into consideration the overall volume of unconfined space, the

number of doors to the outside, internal doors which can close off
unconfined space, and overall tightness of building construction.

Many new buildings and homes (and older ones that have been
weatheiized) MUST BE considered as being tight construction,
therefore, infiltration will not be èuffjcient to supply necessary air
for combustion and ventilation.

A building can be considered as being of tight construction when:

1. Walls and ceilings exposed to outside atmosphere have a
continuous water vapor retarder with a rating of 1 perm or
less with openings gasketed or sealed and/or

2. Wcatherstripping has been added on operable windows and
doors, and/or

5. Caulking or sealants are applied to areas such as joints

around window door. frames; between sole plates and
floors; between wall-ceiling joints; between wall panels; at
penetrations for pluptbing, electrical, and fuel lines; and at
other openings.

If combustion and ventilation air must be supplied to an uncon­fined space from Outside, an opening with ii JExREE AREA of not
less than 1 sq in. per 1ÚÜO Stub of total input of all appliances
within unconfined space (but.nqt.less than .;(Op sq-in.) must be
provided. This opening must be ]pcatcd..such,.that,it.pan pot,be
blocked at any time. ■ ' '

When furnace is installed in a closet or enclosure, 2 ventilatior}
openings, with OPEN AREA as dimensioned in example below

are required for combustion air. The openings ¿houlcí be located

about 6 in. from tOp and bottom of enclosure at front of furnace.

il. DUCTWORK RECOMMENDATIONS

The proper sizing of warm air ducts is necessary to ensure
satisfactory ^mace operation. Ductwork should be in accordance
with the latest editions of NFPA-90A (Installation pf Air Condi
tioning and Ventilating ^yst^ms) and NFPA-90E (Warm Air
Heating and Air Conditioning Systems) or Canadian equivalent

The supply ductwork should be attached to flanged -opening
provided at discharge end of furnace. See Fig. 14 for dimensions
of’this opening'.'

The return air ductwork should be connected to opening on inlet

end pf furnace. AN E?(TERNALLY .MpUNTED AIR FILTER

MUST BE USED WITH THIS FURNACE! The filter .should .be
mounted in return air ductwork in ,a position that j,5., readily
accessible to homeowner. Besure that filter is large enough that,air
velocity through filter (iqps not exceed rating of'filter (typically
300 ft per minute velocity rating). An external filter 'ffaine kit is
available to mount directly to outside of furnace. Contiipt your
dealer for details. ■ ■ ' ■ ‘

The following recommendations should be followed when install
ing ductwork:

1. Install locking type dampers in all branches of individual
ducts,to .balance put system. Dampers should.b.e adjusted to

Impose proper static a'i outlet of furnace. ^

For a confined space, where air . is taken from an interior .space, 2
permanent openings of equal-area-are required. One opening must
be within 12 in, of ceiling and the other within 12 in. of floor. Each
opening must have a free area of at lea^t 1 sq in. per IODO Btuh of
total input rating but no less-'than 1ÖÖ sq fri.

If outside;aír is supplied.to.a confined sp^cc, th6n>th'e .2, openings
must be^e^ual and located a? above. The free Mea of each must be:

1. One sq in. per 4000 Btuh of total rating When air is directly
commupicatEd'-fimm outdoors,if :/-; ... ‘3 "'Xv '

2. One.,i5q jn¿/^^PQQ Btuh of tot^l^ipputräting whqp air is

brought in through .veitical ducts,..

3. Onc^sqihrper 2000'Btuh ortothTiiiptil rating when air is

■■ transferred through horizontal-;ducis',"- /-[-,: 7¡"^~

When ducts are used to siipply airi they must be of the säinc cross

sectional área a$^eb area Of openihgS'ib'which'they com

^ -.'i" V' i-lr. .V.V.'

The minimum dimension of rectangular air ducts must not be less
than 3 in, ^ .

In calculating irfce area,'¿onsideratjon shill be gív'eríTb blocking
effect of loiiverá, grilles, of screen^ protecting opening^.' Screens
used shall not be smaller than 1/4-m. m6sh''ahd 'áíiaí]’be‘readily
accessible for cleaning. If free area through a design of louver or
grille is known, it shall .be used in calculating isjae design and free
area specified.. If design and free area js not known, it may be

assumed that wood louvers havq 20 percpnt free ar,ea, and pietal
louvers and grilles have 60 percent free area. Louvers shall be
fixed in open position or interlocked with furnace so they open
automatically at furnace start-up and remain open during furnace
operalion-

2. A flexible duct cppuector -of,,,noncombustible material
should be installed at unit on both supply-and . retum^air
systems. In applications where extremely quiet operation is
necessary, the first 10 fr (if possible) of supply and return
ducts should be internally'lined with'acoustical material.

3. In cases where return air grille is located dose to fan inlet,
there should 'be at least ope 90^ '¿if turn between _fan inlet
and grille. Further reduction'in sound le^l can be accom
plished by installing acoustical air taming vanes dr lining
duct as described in item 2 above. >

4. When a single air grille is used, duct between grille and
furnace mustfre the same siie'as return Opening in furnace.

CAUTION; Return, air grilles and .-warm ait, registers

A

must not be obstructed. ..r

WARNING: When, supply ducts .cany air circulated by

furnace to areas outside spaces containing furnace^ rptpni
air shall also be handled by a duct sealed to furnace

A

casing and terminating outside space containing frirnace.
Incorrect ductwork termination .and sealing will create a
hazardous condition which could lead to bodily harm-'

When installing furnace with cooling equipment for year round
operation, the following recommendations must be follovyted for
series or parallel airflow;

1, In series airflow applications, coil is mounted after frirnace

in an enclosure in supply-ajr stream. The furnace blower is
used for both heating and cooling airflow.
