INSTALLATION

LIMITATIONS

These units must be installed in accordance with the following applicable national and local safety codes:

In 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 Z21.47a.

4.Local gas and electric utility requirements.

In Canada:

1.Current Canadian Electrical Code C22.1.

2.Current Gas Installation Codes CAN/CGA-B149.1 and .2

3.Local plumbing and waste water codes.

4.Other applicable local codes.

Refer to the Unit Application Data Table and to the Gas Heat Application Data Table.

After installation, units with gas heat 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.

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.

WARNING: Excessive exposure of this furnace to contami- nated combustion air may result in equipment dam- age or personal injury. Typical contaminates in- clude: 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.

4.Roof structures must be able to support the weight of the unit and its options and/or accessories. Unit must be in- stalled 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, 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.

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: On gas heating units, an adhesive backed label is provided over the outside of the combustion air inlet opening to prevent moisture from entering the unit w hich could cause damage to electr ical components. Allow this closure label to remain in place until the combustion air hood is to be installed.

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 Dimensions and Clearances table 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.
