Install Optional Outside Air Kit

The AKU3 Outside Air Kit can be installed to bring com-

bustion air to the heated room air. The air that is drawn

into the heated room air from outside the home or un-

heated area helps relieve the pressure in the home.

The duct termination should be located so it is exposed

to an out-of-doors opening at least 100 square inches. If

the duct termination must be located in a crawl space or

basement, be sure the termination area has 100 square

inches of ventilation opening to outside air.

The duct termination must be located so it does not

compete for air ﬂow with exhaust fans, gas vent hoods

or other air consuming devices or appliances. It must

not be obstructed by rafters, insulation materials or

other obstructions. The less restrictive the air supply,

the better the outside air kits will perform.

It is good practice to protect your hands and eyes

during installation by wearing work gloves and safety

glasses.

CAUTION: Do not install termination into a garage

or other area that could contain ﬂammable liquids

or fumes, or into an attic space.

Installation Instructions

Determine the location of the ﬁreplace as described

in the ﬁreplace installation manual. Then plan location

of the duct termination and the route of the duct run

between the ﬁreplace and the duct termination.

Duct run must be limited to a maximum distance of 40'

(12.2m) from the ﬁreplace pipe collar to duct termina-

tion. This will provide the least restriction to air ﬂow. No

more than four (4) 90° elbows can be used. Duct run

may be horizontal, vertical, inclined or any combina-

tion of these. (Fig. 12) You are now ready to install the

Outside Air Kit.

1. Remove the screws retaining the outside air cover-

plate, if provided. (Located on the left side of front

open units, on backside of multisided units.) Discard

coverplate. (Fig. 13)

2. Secure the inlet collar assembly to the outer casing

with four screws (not provided). (Fig. 14)

3. Slide the duct over the collar and attach the duct

to the collar using the plastic tie straps or three (3)

screws (screws not provided). Continue attaching

the ducting together using three (3) screws at each

joint until you have installed sufﬁcient duct to arrive

at your duct termination locations.

4. At the termination end, install the duct termination.

This should be installed from the outside of the

home. Cut a hole in the desired location approxi-

mately 4¹⁄₂" (114mm) in diameter, caulk around the

hole, and slide the termination through the opening

from outside the home. The termination/rain cap

should be caulked around its perimeter to assure a

tight seal. The rain cap opening should be positioned

downward. (Fig. 15)

The Outside Air Kit is now installed and ready for use.
