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.

1. Insert24 voltwires throughthe smallplasticbushing just
above the control panel.
If required, three (3) sections of Accossory Ring may be used
as shown in Figure 15 to provide closer clearance around 3.

1. Remove the field wiringcover.
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.
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
4. Connect the "ground" wire to the grounding screw.
5. Reinstall the control panel cover and secure mounting
Connect the thermostatwires to the furnace low voltage
pigtails. See Figure17 (heating only) and Figure 18

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.
