Berner IDC12 Series, Installation & Maintenance Instructions Manual

-3-

E.  The air door is weatherproof. Therefore, no special covering 

is required when outdoor mounting unheated, steam, or hot 

water units.  

NOTE:  Electric heated units are to be installed indoors 

only.

F. 

IMPORTANT:

 A minimum of 4” (8” preferred) clearance 

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 effectiveness 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 flush 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.

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 floor.

  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 for Vertical Mounting

III. WALL MOUNTING

A.  Wall mounting works well with standard hinged doors or   

  sliding doors.

B.  The IDC12/IDC14 Series end plates are equipped with ½”   

holes  for wall mounting. The unit may be attached to the wall  

    using, at minimum, ³/8” bolts through the holes on the back  

  of the end plate. 

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 end plate   

  and the wall.  

See Figure 2
