B. OUTSIDE INSTALLATION
(Typical outdoor slab installation is shown in Figure 9.)
1. Select a location where external water drainage cannot collect around unit.
2. Provide a level slab sufficiently high enough above grade to prevent surface water
from entering the unit
3. Locate the unit to provide proper access for inspection and servicing as shown in
Figure 12.
4. Locate unit where operating sounds will not disturb owner or neighbors.
5. Locate unit so roof runoff water does not pour directly on the unit. Provide gutter or
other shielding at roof level. Do not locate unit in an area where excessive snow drift-
ing may occur or accumulate.
6. Where snowfall is anticipated, the height of the unit above the ground level must be
considered. Mount unit high enough to be above anticipated maximum area snowfall
and to allow combustion air to enter the combustion air inlet.
7. Select an area which will keep the areas of the vent, air intake, and A/C condenser
fins free and clear of obstructions such as weeds, shrubs, vines, snow, etc. Inform the
user accordingly.
C. ATTACHING EXHAUST AND COMBUSTION AIR INLET HOODS
IMPORTANT: Do not operate this unit without the exhaust/combustion air inlet hood
properly installed. These hoods are shipped in cartons in the blower compartment
inside the unit and must be attached when the unit is installed. See Figure 4.
To attach exhaust/combustion air inlet hood:
1. Open blower access panel. For location of blower access panel, see Figure 3.
2. Remove exhaust/combustion air inlet hoods from the cartons, located inside the blower
compartment.
3. Attach blower access panel.
4. Attach the combustion air inlet/exhaust hoods with screws. Reference Figure 4 for proper
location. Screws are in carton with the hood.
