The Skuttle Make-Up Air Diffuser allows clean, fresh

air to enter your home whenever there is a negative

air pressure buildup or a need for replacement (make-

up) air.

(e.g., an exhaust vent, sewer vent, dryer vent or

combustion outlet.

3. Install the 6 in. (15.24 cm) ﬂexible duct (not sup-

plied) between the Diffuser and the inlet hood.

NOTE: The Diffuser may be attached directly to the

furnace cabinet. It may also be installed on a nearby

wall or substantial support structure, but must be in-

stalled within 1 ft. (30.48 cm) of the furnace cabi-

net. (See diagram above.)

NOTE: Flexible duct tubing is not supplied be-

cause lengths vary greatly from home to home.

4. Tape and seal all joints. Insulate the tubing in ar-

eas where outdoor winter temperatures drop to

32°F (0°C) or lower, or where water damage could

occur.

CAUTION: Be sure to follow all local codes and or-

dinances.

CAUTION: In homes with extreme negative pres-

sures, the inﬂux of cold outdoor air into the Diffuser

may reduce temperatures in the surrounding area,

possibly resulting in freezing conditions. In cold re-

gions where this could occur, insulate plumbing

or supply additional heat to the area.

INSTALLATION INSTRUCTIONS

1. Mount the Diffuser in a vertical position with the #8

sheet metal screws provided.

DANGER: Do not drill into electrical wiring or re-

frigeration lines during installation.

2. Select a location for the outside air intake vent. Cut

the outside opening to allow room for a 6 in. (15.24

cm) diameter duct to be installed.

CAUTION: To prevent contaminated air from en-

tering the inlet, make sure the Diffuser is at least

10 ft. (3.05 m) from any discharge source
