Non- - powered type: This type requires the field
installation of a general- - purpose 125- - volt 15- - A circuit
powered from a source elsewhere in the building. Observe
national and local codes when selecting wire size, fuse or
breaker requirements and disconnect switch size and
location. Route 125- - v power supply conductors into the
bottom of the utility box containing the duplex receptacle.
Unit- - powered type: A unit- - mounted transformer is
factory- - installed to stepdown the main power supply
voltage to the unit to 115- - v at the duplex receptacle. This
option also includes a manual switch with fuse, located in
a control box and mounted on a bracket behind the
convenience outlet; access is through the unit's control
box access panel. See Fig. 27.
The primary leads to the convenience outlet transformer
are not factory- - connected. If local codes permit, the
transformer primary leads can be connected at the
line- - side terminals on the unit- - mounted non- - fused
disconnect or HACR breaker switch; this will provide
service power to the unit when the unit disconnect switch
or HACR switch is open. See Fig. 29.

Fig. 30 - - Convenience Outlet Utilization Notice
Test the GFCI receptacle by pressing the TEST button on
the face of the receptacle to trip and open the receptacle.
Check for proper grounding wires and power line phasing
if the GFCI receptacle does not trip as required. Press the
RESET button to clear the tripped condition.
Using unit- - mounted convenience outlets: Units with
unit- - mounted convenience outlet circuits will often
require that two disconnects be opened to de- - energize all
power to the unit. Treat all units as electrically energized
until the convenience outlet power is also checked and
de- - energization is confirmed. Observe National Electrical
Code Article 210, Branch Circuits, for use of convenience
outlets.
Factory- - Option Thru- - Base Connections —
All units are equipped with the ability to bring utilities
through the base.
Gas is brought up through an embossed area located in the
gas section behind the gas entrance post. Access is gained
through the gas access panel. A knock out must be
removed to accomplish this.
The electrical entrance is located in the control box area
can can be accessed through the control box access panel.
An embossed area is provided with three knock outs. High
voltage is brought through the multi knock out by
removing the appropriate size for the size of the fitting
7
required. A

An additional
/
- - in. knock out is provided for a 115 volt

line which is used when the unit is equipped with the
non- - powered convenience outlet option.
All required fittings are field supplied. Install fittings
when access to both top and bottom of the base pan is
available. See electrical and gas connections for routing
and connection information.
Units Without Thru- - Base Connections —
1. Install conduit, liquid tight, between disconnect and
control box.
2. Pull correctly rated high voltage wires through the
conduit.
3. Install power lines to terminal connections as shown
in Fig. 26.
