CEILING RINGS

The coiling ring is to meet fire stop requirements. Accessory Ceiling Ring (PIN 7660-2841) may be used, (See Figure 15) or the manufactured home manufacturer or the installer may use other approved methods to stop fire.

If required, three (3) sections of Accossory Ring may be used

as shown in Figure 15 to provide closer clearance around roof jack,

TO INSTALLER: Incoming power must be polar- ized. Observe color coding.

AWARNING!

SHOCK HAZARD - DISCONNECT ELECTRI- CAL POWER SUPPLY TO THE UNIT BEFORE SERVICING TO AVOID THE POSSIBILITY OF

SHOCK INJURY OR DAMAGE TO THE EQUIP- MENT

CONNECT POWER SUPPLY WIRES

1.Remove the field wiring cover.

2, Insert 115 volt wires through the large plastic bushing on the left side of the furnace (See Figure 16). If conduit is used it should be secured to the control box.

3.Connect the "hot" wire to the BLACK pigtail lead, and the "neutral" wire to the WHITE pigtail lead. Secure all con- nections with suitable wire nuts and wrap with electrical tape.

4.Connect the "ground" wire to the grounding screw.

5.Reinstall the control panel cover and secure mounting

screw,

CONNECT THERMOSTAT WIRES

1.Insert 24 voltwires throughthe small plastic bushing just above the control panel.

2.Connect the thermostat wires to the furnace low voltage pigtails. See Figure17 (heating only) and Figure 18 (heating and cooling).

3.

Connect low-voltage circuit to the wall thermostat pig- tails.

NOTE: Five-conductorthermostat cable is recommended for

all installations to allow easy installation of an air conditioning system at a later time.

Eighteen gauge thermostat wire is highly recommended.

Smaller gauge thermostatwire may be used only if the guide- line below is followed.

THERMOSTAT WIRE				THERMOSTAT
LENGTH	(FURNACE		TO
				WlRE GAUGE
THERMOSTAT)
0	- 45	feet		22
0	- 70	feet		20

Do not use thermostat wire smaller than 22 gauge. If thermo-

stat wire smaller than 18 gauge is used, pay particular atten- tion that the connections between the different wire sizes are

tight.

Operational problems may be caused by loose connections or by the use of thermostat wire that is too small to carry the

required load. Any such problems are the responsibility of the installer.

Aseparate 115 _/A.C. supply circuit must be used for the fur-

naco. The circuit should be protected by a 15 amp fuse or cir- cuit breaker.
