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 2x4 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.
