INSTALLING YOUR MOTORIZED
REAR OUTLET ACCESSORY
MOTORIZED REAR OUTLET REGISTER 6919 AND 6920
WARNING: Danger of property damage, bodily
injury or death. Turn off all electrical power supply at
disconnect switch, fuse box or service panel before
removing or working on fan. For your protection
against shock hazard, this appliance is equipped
with a three-prong (grounding) plug and should be
plugged directly into a properly grounded three-
prong receptacle. Do not cut or remove the prong. All
electrical work must conform to your local codes and
ordinances or in their absence, with National Electrical
Code ANSI/NFPA 70. In Canada, use the Canadian
Electrical Code C22.1. If you are not familiar with the
wiring codes in general, have a competent electrician
do this job.
MOTORIZED REAR OUTLET REGISTER 6919 AND 6920
This Rear Outlet Register directs some of the heated air
into the room opposite the one in which the furnace is
installed. Read these instructions carefully and familiarize
yourself with the installation before you begin. Use gloves
to protect your hands from sharp metal edges.
BLOWER SETTINGS
You must select "ON" for continuous blower operation or
"AUTO" for automatic setting. If the blower is set on "AUTO"
when the furnace heats up, the heat sensor switch is
activated and the blower will operate until the furnace cools
down, then the blower will turn off. The blower will not
operate if fan switch is set in the "OFF" (center) position.
LOCATION WARNING
This register must be centered between studs and aligned
with the furnace for proper engagement. Make sure the
furnace is centered between the same studs before you
cut any wall openings for the register.
1. Measure and mark wall for opening as shown in
Figure A. Check the wall for any electrical wiring
present before cutting the opening. Reroute existing
electrical if necessary.
2. If recessed-mounted installation, place the plaster
ground in the opening and attach to the 2 x 4 studs.
3. An embossed knockout plate is located on the rear
of the outer shield and another is located directly
behind it on the inner shield Figure B. Remove the
knockout plates on the furnace by punching in the
lower corners of the plate with a screwdriver blade.
Then, holding the screwdriver blade sideways against
the side and bottom connecting tabs, strike the head
of the screwdriver lightly with a hammer to break the
tabs. Swing the plate outward and bend it back and
forth to break the top tabs. Both knockout plates must

be removed in order to attach the register assembly
properly. If the inner shield knockout is not embossed
deep enough to be removed easily, mark an outline
using the existing opening as a guide. Use tin snips to
cut the area away. A pilot hole may be needed to begin
the first cut. Take care not to damage the combustion
chamber directly behind the inner shield when making
a pilot hole.
4. Attach speed nuts to the outer shield (Figure B). After
the furnace is in position, insert the outlet register
into the opening as shown in Figures C, D and E. Install
machine screws through the register housing and into
the speed nut clips on the furnace outer shield. Do not
over tighten the screws.
5. After the register has been either wired, Figure F,
or plugged in, set the fan switch to the desired
blower operation.
CAUTION: Do not install this kit where the outlet grille
may be blocked or covered by a door, curtains or any
other obstructions.
