LOCATIONS AND RECOMMENDATIONS

continued from page 7

Examine all flue product-carrying areas of the furnace, its vent system, and the main burner for safe operation. A periodic inspection of the furnace should be made at the start of each heating season.

Replacement parts list for this Gas/Electric Air Conditioner may be obtained by contacting your local manufacturer representa- tive.

6.Location of the unit must allow for service clearance around it. Clearance of the unit must be given careful consideration. See Figure 4.

7.IMPORTANT: The air outlet duct must have one (1) inch clearance to combustible material downstream from the unit.

8.Exhaust vents or other sources of contaminated air should not be near the unit’s air inlet, if outside air is to be introduced as makeup air or a ventilation feature is to be used.

9.Check the handling facilities to ensure the safety of personnel and the unit(s).

10.Caution must be taken at all times to avoid personal injuries and/or damage to the equipment.

11.The unit must be mounted level for proper drainage of water through the holes in the base pan.

12.The unit must not be exposed to direct roof water runoff.

13.Flexible duct connectors must be of a flame retardant material. All duct work outside of the structure must be insulated and weatherproofed in accordance with local codes.

14.Roof flashing must be installed to seal the roof curb cavity and must conform to local building codes.

15.Access and service clearances for the unit must be given careful consideration when locating the duct entrance open- ings. Figure 4 provides unit dimensions.

16.All fabricated outdoor ducts should be as short as possible.

CLEARANCES

1.The recommended clearances for single-unit installations are illustrated in Figure 4. These minimum requirements are not only an important consideration when determining unit place- ment, but they are also essential to ensure adequate service- ability, maximum capacity, and peak operating efficiency.

2.Any reduction of the unit clearances indicated in these illustra- tions may result in condenser coil starvation or the recirculation of warm condenser air. Actual clearances which appear to be inadequate should be reviewed with a local sales engineer.

IMPORTANT:

1.Remove the Flue and Air Inlet Hood with the gasket from the return air section of the unit.

The screws that attach the flue and air inlet hood will be installed in their proper location at the factory. Therefore, they must be removed and then used to attach the flue and air inlet hood.

2.Remove the packaging material from the components and secure the Flue and Air Inlet Hood with the gasket to the unit with sheet metal screws as illustrated in Figure 16 on page 14.

NOTE: Outdoor air or other requirements during heating operation that result in supply air temperatures below 80 degrees F or return air temperatures below 50 degrees F may cause flue gas condensate to form and is to be avoided.

INSTALLATION

UNIT SUPPORT PLACING AND RIGGING

If the unit is to be roof mounted, check the appropriate building codes for weight distribution requirements. Refer to the applicable roof curb mounting instruction. Check the unit’s nameplate for supply voltage required. Determine if adequate electrical power is available. The furnace may be installed on Class A, B, or C roofing material.

LOCATION AND CLEARANCES

Installation of the unit should conform to local building codes or, in the absence of local codes, to the National Fuel Gas Code, ANSIZ223.1, Latest Revision, and the National Electrical Code. Canadian installations must conform to CSA and local codes.

Select a location that will permit adequate combustion and ventila- tion air in accordance with Section 5.3, Air For Combustion and Ventilation, of the National Fuel Gas Code, ANSIZ223.1, Latest Revision, or applicable provisions of the local building code.

1.Before preparing the unit for lifting, check the outline drawing for center of gravity for lifting safety. Because of placement of internal components, the unit’s weight may be unevenly distrib- uted. Approximate unit weights are given in Figure 2, page 3.

NOTE: Accessory BAYLIFT002AA, a kit of four (4) lifting lugs, is required for rigging the unit for hoisting. See Figure 7, insert B.

2.Insert the four lifting lugs in the openings provided in the drip lip on the perimeter of the unit. See Figure 7, insert B. A tap or jerk to the lug will overcome the interference that arises due to the nipple on the lug.

3.Before hoisting the unit, be sure that the proper method of rigging is used, with straps or slings and spreader bars for protection during lifting. Always test-lift the unit to determine the exact unit balance and stability before hoisting it to the installa- tion location.
