LIMITATIONS

These units must be installed in accordance with the current

edition of the following national and local safety codes:
In the U.S.A.:
1. National Electrical Code ANSI/NFPA No. 70.
2. National Fuel Gas Code Z223.1.
3. Gas-Fired Central Furnace Standard ANSI Z21.47-1993.
4. Local gas utility requirements.
In Canada:

1. Canadian Electrical Code CSA C22.1

2. Current Gas Installation Codes CAN/CGA-2.3-M93.
3. Local plumbing and waste water codes.
4. Other applicable local codes.
Refer to Table 1 for Unit Application Data and to Table 2 for Gas

Heat Application Data.
If components are to be added to a unit to meet local codes, they

are to be installed at the dealer's and / or the customer's expense.
Size of unit for proposed installation should be based on heat

loss / heat gain calculation made according to the methods of

Air Conditioning Contractors of America (ACCA).

LOCATION

Use the following guidelines to select a suitable location for

these units.
1. Unit is designed for outdoor installation only.
2. Condenser coils must have an unlimited supply of air.

Where a choice of location is possible, position the unit on

either north or east side of building.

WARNING:Excessive exposure of this furnace to contami-

nated combustion air may result equipment dam-

age or personal injury. Typical contaminates

include: permanent wave solutions, chlorinated

waxes and cleaners, chlorine based swimming

pool chemicals, water softening chemicals, carbon

tetrachloride, Halogen type refrigerants, cleaning

solvents (e.g. perchloroethylene), printing inks,

paint removers, varnishes, hydrochloric acid, ce-

ments and glues, antistatic fabric softeners for

clothes dryers, masonry acid washing materials.

3. For ground level installation, a level pad or slab should be

used. The thickness and size of the pad or slab used should

meet local codes and unit weight. Do not tie the slab to the

building foundation.

4. Roof structures must be able to support the weight of the

unit and its options and / or accessories. Unit must be

installed on a solid level roof curb or appropriate angle iron

frame.

CAUTION: If a unit is to be installed on a roof curb or special

frame other than a YORK roof curb, gasketing

must be applied to all surfaces that come in contact

with the unit underside.

5. Maintain level tolerance to 1/2" maximum across the entire

length or width of the unit.

6. Elevate the unit sufficiently to prevent any blockage of the

air entrances by snow in areas where there will be snow

accumulation. Check the local weather bureau for the

expected snow accumulation in your area.

RIGGING AND HANDLING

Exercise care when moving the unit. Do not remove any

packaging until the unit is near the place of installation. Rig the

unit by attaching chain or cable slings to the lifting holes

provided in the base rails. Spreaders, whose length exceeds

the largest dimension across the unit, MUST be used across

the top of the unit.
BEFORE LIFTING A UNIT, MAKE SURE THAT ITS WEIGHT

IS DISTRIBUTED EQUALLY ON THE CABLES SO THAT IT

WILL LIFT EVENLY.
Units may also be moved or lifted with a forklift. Slotted

openings in the base rails are provided for this purpose.
LENGTH OF FORKS MUST BE A MINIMUM OF 42".
Remove the nesting brackets from the four corners on top of

the unit. All screws that are removed when taking these

brackets off must be replaced on the unit.

CAUTION: An adhesive backed label is provided over the out-

side of the combustion air inlet opening to prevent

moisture from entering the unit which could cause

damage to electrical components. Allow this clo-

sure label to remain in place until the combustion

air hood is to be installed (refer to Figure 6).

Refer to Table 4 for unit weights and to Figure 1 for approximate

center of gravity.

CLEARANCES

All units require certain clearances for proper operation and

service. Installer must make provisions for adequate

combustion and ventilation air in accordance with Section 5.3,

Air for Combustion and Ventilation of the National Fuel Gas

Code, ANSI Z223.1 (in U.S.A.) or Sections 7.2, 7.3 or 7.4 of

Gas Installation Codes CAN/CGA-B149.1 and .2 (in Canada)

and/or applicable provisions of the local building codes. Refer

to Figure 9 for the clearances required for combustible

construction, servicing, and proper unit operation.

WARNING:Do not permit overhanging structures or shrubs to

obstruct condenser air discharge outlet, combus-

tion air inlet or vent outlet.

DUCTWORK

Ductwork should be designed and sized according to the

methods in Manual Q of the Air Conditioning Contractors of

America (ACCA).
A closed return duct system shall be used. This shall not

preclude use of economizers or outdoor fresh air intake. The

supply and return air duct connections at the unit should be

made with flexible joints to minimize the transmission of noise.
