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 o 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 qualied person(s) in accordance with all applicable codes and standards, including
re-rated construction.
D. Sucient air is needed for proper combustion and exhausting of gases through the ue (chimney) of fuel burning equipment to prevent
back drafting. Follow the heating equipment manufacturer’s 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. UNCRATING
Carefully examine the carton(s) for damage before opening. If
the carton is damaged, immediately notify shipping company.
If the unit(s) were shipped on wooden skids, remove protective wood and banding straps securing the carton(s) to the
skid. Open the carton(s) and remove all protective packaging.
Immediately verify that the electrical rating nameplate located
on the cover matches electrical power supply available. Retain
the shipping carton(s) until the unit(s) is installed and properly
operating.
ACCESSORIES: If the unit(s) were ordered with optional electrical accessories (door switch, control panel, etc.), the accessories
may be found in the carton containing the unit or in a separate
carton(s) accompanying the unit(s). Check all of the cartons/
skids for accessories before discarding.
II. MOUNTING INSTRUCTIONS
(General Notes for All Mounting Congurations)
INDOOR MOUNTING - Environmental/Insect/Dust Control
OUTDOOR MOUNTING (Unheated Only) - Insect/Dust Control
A. Berner VSA and VSB Series Air Doors are designed to
be mounted by their end anges without the need for
intermediate support. Each end ange contains (8) total ½”
holes located on all (4) sides to facilitate mounting exibility
and the easy addition of mounting accessories. Units may
be attached to the wall directly, suspended from overhead,
or supported by brackets. The style of door will determine
the best mounting method and; as a general rule, use the
mounting conguration that positions the air door as close
to the top of the doorway as possible without interfering
with door operation.
B. The VSA/VSB air door is designed to be an eective barrier
against cold drafts in the winter and hot air in the summer.
To achieve optimum protection, the unit should be mounted
on the inside of the building, ush to the wall and as close
TABLE 2
to the top of the door opening as possible. To ensure peak
performance keep the air stream free of obstructions. If
the air door cannot be installed ush with the wall, be sure
to seal the gap between the wall and the back of the Air
Door along the entire length of the unit to prevent airow
through this void.
C. The air door will not perform properly if negative air
pressure exists in the building. Under these conditions,
a means for makeup air to the building must be
provided so that the air pressure on both sides of the
opening is in balance.

D. Before mounting the air door, check the supporting
structure to verify that it has sucient 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
Tables 1 & 2.
E. The air door is weatherproof. Therefore, no special covering
is required when outdoor mounting, unheated, steam, or
hot water units.
F. IMPORTANT: A minimum of 4” (8” preferred) is
recommended above the top of the Air Door for the
installation and removal of the screen or to gain access to
junction boxes.
G. When determining the mounting location for the unit(s),
make sure that nothing interferes with the curtain of air
developed when the discharge vanes are directed from 0º
to 20º toward the door opening. If the air stream strikes any
obstruction (the top edge of the doorway, a door opening
device, etc.), the eectiveness of the unit will be greatly
reduced. See Drawing 1.
H. For optimum performance, the bottom of the unit
(discharge nozzle) should be no more than 1” above the top
of the door opening with the unit mounted ush to the wall.
If the unit must be mounted higher, it must be spaced out
from the wall ³/₈” for every inch the unit is above the door
opening. See Drawing 2.

III. WALL MOUNTING
A. Wall mounting works well with standard hinged doors or
sliding doors.
B. The VSA/VSB series endplates are equipped with ½” holes
for wall mounting. The unit may be attached to the wall
using, at minimum, /” bolts through the holes on the back
of the endplate. See Figure 1. Or, the unit may be attached
using an optional wall mounting bracket or a combination
of extension and wall mounting brackets (available from
Berner) attached to the holes on the top of the endplate
and the wall. See Figure 2.
DRAWING 2
I. Electric heated units shall:
1. Have a minimum clearance of at least 1” between the
sides and top of the unit and any combustible material.
2. Have a minimum clearance of at least 6’ between the
bottom of the unit and the oor.
3. Be installed indoors only.
J. Proceed to one of the following sections, depending on
application and door type:
Section III: Wall Mounting
Section IV: Suspended Mounting
Section V: Vertical Mounting
Section VI: Tandem Mounting Brackets
