Installing Your Motorized Rear Outlet Accessory - Williams AC2030 Owner's Manual

DANGER: The build-up of any dust, lint or foreign
material in the primary air opening of the burner can
interfere with the proper air gas mixture and can result
in a yellow flame which can produce carbon monoxide
and soot. This condition, if allowed to develop, can lead
to bodily injury including death. It is imperative that the
burner be kept clean.
CAUTION: Danger of property damage, bodily injury or
death. Turn off electric power supply at the disconnect
switch, fuse box or service panel before removing or
working on the fan cabinet.

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.

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
