UNCRATING
This unit was quality inspected and tested immediately prior to packaging and was in operating condition at that time. Check the
shipping carton and unit for any damage that may have occurred during shipment. If damage is found, notify the shipping company
immediately.
The AURA Series air door is shipped completely assembled. Remove the accessory box and the louvered discharge grille (wrapped in
protective paper) from the carton. Remove the AURA Series air door from the carton. See Figure 1. Immediately upon unpacking the
unit, verify that the rating nameplate agrees with the electric supply available.
Do NOT attach the louvered discharge grille or perforated intake grille at this time.

WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
A. Use this unit only in the manner intended by the manufacturer. If you have any questions, contact the manufacturer.
B. Before servicing or cleaning unit, switch power off at service panel and lock the service disconnecting means to prevent
power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a
prominent warning device, such as a tag, to the service panel.
C. Installation work and electrical wiring must be done by qualified person(s) in accordance with all applicable codes and
standards, including fire-rated construction.
D. Sufficient air is needed for proper combustion and exhausting of gases through the flue (chimney) of fuel burning equipment
to prevent back drafting. Follow the heating equipment manufacturers guideline and safety standards such as those
published by the National Fire Protection Association (NFPA), and the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and local code authorities.
E.
When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden utilities.

I. MOUNTING INSTRUCTIONS
(All Models)
A. Before mounting the unit, check the supporting structure to
verify that it has sufficient load-carrying capacity to support
the weight of the unit(s). The mounting hardware (supplied
by others) should be capable of supporting a minimum of three
(3) times the weight of the unit. See Table 1.
B. Nothing should interfere with the curtain of air developed when
the discharge grille vanes are directed 20° toward the door
opening. If the air stream strikes any obstruction (the top
edge of the doorway, a door opening device, etc.), the effec-
tiveness of the unit will be greatly reduced.

.For optimum performance, the bottom of the unit (discharge
grille) should be a maximum of 1 above the top of the door
opening with the unit mounted flush to the wall. If the unit
must be mounted higher, it must be spaced out from the wall
3

for every inch the unit is above the door opening (maxi-
mum recommended mounting height of 10). Where pos-
sible (installation site permitting), for optimum protection,
any void between the air door and the wall should be sealed
along the full length of the unit.
D. Do not block (obstruct) the air intake grille. Insufficient air
flow can cause the unit to overheat.
E. Electric heated units should have:
1. A minimum clearance of at least 4 between the sides and
top of the unit and any combustible material.
2. A minimum clearance of at least 6 between the bottom of
the unit and the floor.
Proceed to either Suspended or Wall Mounting Instruc-
tions.
II. SUSPENDED MOUNTING
A. NO BACK ADAPTOR: Figure 2
1. Suspend the AURA Series air door on the inside of the
building with the louvered discharge grille facing the door
opening. See Figure 2.
2. Mount and level the air door by connecting four (4)

threaded rods or other suitable hardware (supplied by oth-
ers) to the (4)

threaded inserts located on top of the
unit.

B. WITH BACK ADAPTER: Figures 3 & 4
1. The unit may be mounted with the louvered discharge
grille facing toward the door opening, or the interior of
the building (electric heated models only). See Figures
3 and 4.
2. Figure 3 installation (louvered discharge grille facing in-
terior of the building). Follow instructions A & B above.
3. Figure 4 installation (louvered discharge grille facing in-
terior of the building). A maximum of 6 between the
wall and intake grille is required. Install the back adap
tor at this time. Follow instructions 2 under Item A.
FIGURE 3 - Suspension Mount with Back Adapter
C. ABOVE CEILING: Figure 5
Follow instructions 1 & 2 under Item A. See Figure 5. The
bottom of the unit can be exposed for easy servicing.
D. DO NOT install the perforated intake grille or the lou-
vered air discharge grille at this time. Proceed to Section
IV ELECTRICAL CONNECTIONS.
III.
WALL MOUNTING
(Optional Wall Mounting Bracket Required)
See Figures 6-10
A. When the AURA Sseries air door is for wall mounting, four
5/16 shoulder bolts will be pre-assembled on the back of the
unit (opposite the perforated intake grille).
B. The wall mounting plate is designed to fit flush with the back
of the entire AURA door.
C. Determine the exact location of the air door unit. Position the
center of the wall mounting plate over the center of the door
opening with the larger opening of the key hole slots facing
up.
For optimum performance, the bottom of the mounting plate
should be no more than 1 above the top of the door opening.
STANDARD WALL MOUNTING: Figure 7A. The wall
mounting plate thickness provides a natural 1

/

space which
allows for mounting up to 4 above the opening.
HIGH WALL MOUNTING: If the wall mounting plate must
be mounted higher than 4 above the door opening, it must be
spaced out from the wall
3
/
8
for every inch the unit is above
the door opening. See Figure 7B.
For optimum performance, do not exceed the recommended
maximum mounting height of 10 above the finished floor.
For optimum protection, any void between the mounting plate
and the wall should be sealed along the full length of the
mounting plate.

D. Mark the wall in the centers of the (4) ½ round holes pro-
vided on the mounting plate. See Figure 6. If the holes on
the mounting plate are not located where suitable support is
available for the unit, drill new holes in the space provided on
the mounting plate.
E. Drill the four holes as marked on the wall and attach the mount-
ing plate to the wall (mounting hardware by others).
F. Raise the air door with the discharge opening facing down
toward the floor. While holding the unit level, slide the heads
of the shoulder bolts into the larger hole of the key-
hole slots of the mounting plate. Lower the unit into place,
keeping both ends level, allowing it to rest flush with the
mounting plate. See Figure 9.
G. After attaching the unit to the mounting plate, check to ensure
the unit is seated and flush with the mounting plate on all four
sides.
H. Do not install the perforated intake grille or the louvered dis-
charge grille at this time.
Proceed to Section IV - Electrical Connections.

ELECTRICAL CONNECTIONS
A. All electrical wiring and connections MUST be performed
by qualified personnel in accordance with the National elec-
trical Code ANSI/NFPA No. 70 (latest edition) or, in Canada,
the Canadian Electrical Code, Part 1-C.S.A. Standard C22.1
and local codes and regulations.
WARNING: DO NOT OPERATE THIS FAN WITH ANY
SOLID STATE SPEED CONTROL DEVICE.
B. Check the rating nameplate on the top of the unit, or inside
the bottom access cover, for supply voltage and current
requirements. See Figure 11. A separate line voltage supply
with a suitable branch circuit protection device should be run
directly from the main electrical panel of the unit. A disconnect
switch for each branch circuit is a required part of this
installation.
C. All field wiring must be copper with a minimum insulation of
60°C within approved conduit. If any of the wire supplied
with the unit must be replaced, it must be replaced with cop-
per wiring with a minimum insulation of 90°C.
D. Access the wiring compartment, See Figure 11, by lowering
the bottom hinged access cover. Remove the two ¼ bolts
located on the intake side of the unit and the access cover will
swing down to rest in the vertical position exposing the wir-
ing compartment. If desired, the access cover may be removed
by grasping both sides of the access cover and pressing in on
the spring lo
