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.
