LIMITATIONS

These units must be installed in accordance with the following

national and local safety codes:

1. National Electrical Code ANSI/NFPA No. 70.

2. National Fuel Gas Code Z223.1.

3. Gas-Fired Central Furnace Standard ANSI Z21.47a.

4. Local gas utility requirements.

Refer to Table 1 for Unit Application Data and to Table 2 for Gas

Heat Application Data.

After installation, the unit must be adjusted to obtain a

temperature rise within the range specified on the unit rating

plate.

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

the Air Conditioning Contractors of America (ACCA).

This furnace is not to be used for temporary heating of buildings

or structures under construction.

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

contaminated combustion air may result

equipment damage 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, cements and glues,

antistatic fabric softeners for clothes dryers,

masonry acid washing materials.

3. For ground level installation, use a level concrete slab with

a minimum thickness of 4 inches. The length and width

should be at least 6 inches greater than the unit base rails.

Do not tie 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.

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 round 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. Refer to Figure 1.

Units may also be moved or lifted with a forklift, from the front

or rear only, providing that an accessory skid is used.

LENGTH OF FORKS MUST BE A MINIMUM OF 90".

CAUTION: An adhesive backed label is provided over the

outside of the combustion air inlet opening to

prevent moisture from entering the unit which could

cause damage to electrical components. Allow this

closure label to remain in place until the

combustion air hood is to be installed (refer to

Figure 8).

Refer to Table 5 for unit weights and to Figure 2 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 10 for the clearances required for combustible

construction, servicing, and proper unit operation.

WARNING:Do not permit overhanging structures or shrubs to

obstruct outdoor air discharge outlet, combustion

air inlet or vent outlets.

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 noise.

The supply and return air duct systems should be designed for

the CFM and static requirements of the job. They should

NOT
