Assembly Instructions

Description
The Adjustable Frame Intake/Exhaust Louvers are fabricated from
galvanized steel or .040 aluminum. Both galvanized and aluminum
products are 4" deep with 2" face flange and come with rear
mounted bird screen. Fixed height is standard and width is
adjustable. Louvers have end stops to help prevent separation of
sections.
Louvers may be used in HVAC intake and exhaust systems and
many air moving applications. They are usually installed in openings
of interior or exterior walls, roof penthouses and ductwork.
General Safety Information
WARNING: USE CAUTION WHEN HANDLING SHEET METAL
PRODUCTS. PROTECTION SHOULD BE USED TO AVOID
CONTACT WITH SHARP EDGES OR INJURY MAY OCCUR.
Unpacking
When unpacking, carefully remove louver from carton
and inspect for any damage that may have occurred
during transit.
Installation
The Adjustable Frame Intake/Exhaust Louvers are
galvanized steel or mill finish aluminum, and may be
painted, provided proper surface pre-treatment is
performed prior to paint application. Note that unit must
be adjusted to its final width prior to painting. Refer to
paint manufacturers instructions prior to
pretreating and painting.
1. To install the louver, first prepare the wall or duct
opening to accept the louver. The wall opening should
be
1
/
4
" to
1
/
2
" larger than the final fixed dimension of the
louver. Make sure that the opening is plumb and level,
and sufficient structural support is provided, as the
louver is not
load bearing.
2. After the opening is prepared, measure its width by
height and, on the ground, adjust the louver to the
required opening width.
3. Carefully extend the louvers to the desired width.
Take care not to use excessive force, as it is possible
to overcome the stops. Open the louver evenly to
prevent jamming. Do not exceed maximum width
dimension. (See Figure 1)

NOTE: When louver is adjusted to proper
width, both jambs must be parallel.
