(4.) Outlet shall include 15 amp GFI receptacles with independent fuse protection.
(5.) Voltage required to operate convenience outlet shall be provided by a factory--installed step--down trans-

former.

(6.) Outlet shall be accessible from outside the unit.

b. Non--Powered convenience outlet.

(1.) Outlet shall be powered from a separate 115/120v power source.
(2.) A transformer shall not be included.
(3.) Outlet shall be factory--installed and internally mounted with easily accessible 115--v female receptacle.
(4.) Outlet shall include 15 amp GFI receptacles with independent fuse protection.
(5.) Outlet shall be accessible from outside the unit.

10. Flue Discharge Deflector:

a. Flue discharge deflector shall direct unit exhaust vertically instead of horizontally.

b. Deflector shall be defined as a “natural draft” device by the National Fuel and Gas (NFG) code.

11. Centrifugal Propeller Power Exhaust:

a. Power exhaust shall be used in conjunction with an integrated economizer.

b. Independent modules for vertical or horizontal return configurations shall be available.

c. Horizontal power exhaust is shall be mounted in return ductwork.

d. Power exhaust shall be controlled by economizer controller operation. Exhaust fans shall be energized when

dampers open past the 0--100% adjustable setpoint on the economizer control.

12. Roof Curbs (Vertical):

a. Full perimeter roof curb with exhaust capability providing separate air streams for energy recovery from the

exhaust air without supply air contamination.

b. Formed galvanized steel with wood nailer strip and shall be capable of supporting entire unit weight.

c. Permits installation and securing of ductwork to curb prior to mounting unit on the curb.

13. High Altitude Gas Conversion Kit:

a. Package shall contain all the necessary hardware and instructions to convert a standard natural gas unit to op-

erate from 3,000--10,000 ft (914 to 3048m) elevation and 10,001--14,000 ft (3049--4267m) elevation.

14. Outdoor Air Enthalpy Sensor:

a. The outdoor air enthalpy sensor shall be used to provide single enthalpy control. When used in conjunction

with a return air enthalpy sensor, the unit will provide differential enthalpy control. The sensor allows the unit

to determine if outside air is suitable for free cooling.

15. Return Air Enthalpy Sensor:

a. The return air enthalpy sensor shall be used in conjunction with an outdoor air enthalpy sensor to provide dif-

ferential enthalpy control.

16. Indoor Air Quality (CO

2

) Sensor:

a. Shall be able to provide demand ventilation indoor air quality (IAQ) control.

b. The IAQ sensor shall be available in duct mount, wall mount, or wall mount with LED display. The setpoint

shall have adjustment capability.

17. Smoke detectors:

a. Shall be a Four--Wire Controller and Detector.

b. Shall be environmental compensated with differential sensing for reliable, stable, and drift--free sensitivity.

c. Shall use magnet--activated test/reset sensor switches.

d. Shall have tool--less connection terminal access.

e. Shall have a recessed momentary switch for testing and resetting the detector.

f. Controller shall include:

(1.) One set of normally open alarm initiation contacts for connection to an initiating device circuit on a fire

alarm control panel.

(2.) Two Form--C auxiliary alarm relays for interface with rooftop unit or other equipment.
(3.) One Form--C supervision (trouble) relay to control the operation of the Trouble LED on a remote test/reset

station.

(4.) Capable of direct connection to two individual detector modules.
(5.) Can be wired to up to 14 other duct smoke detectors for multiple fan shutdown applications

18. Winter start kit

a. Shall contain a bypass device around the low pressure switch.
