Important installation requirements
Roof pitch
FS is designed for roof pitches 14° - 85° (3:12 - 137:12). In case of roof
pitches below 14° (3:12), please contact your VELUX sales company for
installation guidelines.
Importance of proper installation
Satisfactory product performance depends on proper installation.
Seller accepts no responsibility whatsoever for failure of an installer to

roof windows and skylights in accordance with these
installation instructions. Although VELUX roof windows and skylights are
designed and manufactured to the highest standards, severe climatic ex-
posure as well as adverse indoor conditions (ie high humidity) may produce
temperature conditions which exceed product performance standards. In
these cases, special preventive measures may be necessary.
Seller reserves the right to implement product changes for improvement
without prior notification.
Sunscreening accessories
Refer to instructions for accessory type in question or contact your
VELUX sales company for further information.
Vapor barrier
Where a vapor barrier is part of the roof construction, this barrier must be
extended and connected to the skylight finish groove.
Treatment of wooden frame
Most VELUX skylights are pre-painted white but the option exists to order
stain grade skylights. These stain grade skylights received a temporary
treatment against mold and mildew. Further treatment with wood stain,
paint etc is necessary and can be done prior to installation or shortly after
installation. Care should be taken to ensure wood stain, paint etc is not
applied to gaskets.
Consult local jurisdictions and authorities for recycling and proper
disposal of removed skylights and materials.
NOTICE
Skylights and interior surfaces in older homes may have been painted
with lead-based paint, and removal of the skylights may disturb this
paint. Take proper precautions to minimize exposure to dust and debris.
For more information on the proper removal of lead paint go to
www.epa.gov/lead.
Seller assumes no obligation whatsoever for failure of an architect,
installer or building owner to comply with all applicable laws, ordi-
nances, building codes and safety requirements.
NOTICE
In rare circumstances, all glass may be subject to unexpected and spon-
taneous breakage due to imperfections in the glass that are undetectable
during the manufacturing and inspection process by the manufacturer of
the glass and the VELUX factory.
Your VELUX sales company offers the choice of laminated or tempered
glass skylights. Laminated glass is a combination of two or more glass
sheets with one or more interlayers of plastic (PVB) or resin. In case of
breakage, the interlayer is designed to hold the fragments together. Tem-
pered glass does not contain an interlayer to hold the fragments together.
Instead, tempered glass is designed to break into small, pebble-like pieces.
When tempered glass breaks, pieces of glass come loose and may strike an
individual.
Consult local regulations and/or building material consultants to
determine which type of glass is right for you or if laminated glass is
required in your application.

series A21 skylights are designed and engineered to be installed
with VELUX flashing systems. VELUX flashing systems include VELUX ad-
hesive skylight underlayment in a quantity sufficient to install one skylight
of the size for which the flashing system was designed.
The VELUX "No Leak" installation warranty is based upon installation
strictly in accordance with VELUX deck or curb mounted skylight and re-
lated deck or curb mounted flashing installation instructions, which specify
the use and proper installation of the VELUX adhesive skylight underlay-
ment packaged with the flashing system.
If VELUX adhesive skylight underlayment is not used or is not properly in-
stalled and a service issue occurs related to underlayment omission, failure,
or its proper installation as detailed in the VELUX deck or curb mounted
skylight and deck or curb mounted flashing installation instructions, the
VELUX "No Leak" installation warranty is void.
VELUX America Inc. understands that there are other types of adhesive
underlayment that are of equal or higher quality than what is provided
by VELUX America Inc. However, VELUX America Inc. cannot approve
or validate that any specific type of adhesive underlayment is better or
worse. Thus, VELUX America Inc. places the risk of using an alternative
adhesive underlayment onto the specifier by stating that if the alternative
underlayment becomes a failure point for the skylight or flashing system
even if installed according to our instructions, then the VELUX "No Leak"
installation warranty cannot be honored. Further, the alternative underlay-
ment must not in any way obstruct, alter or prevent the proper functioning
of the complete skylight and flashing installation, such as increasing the
overall flashing system thickness beyond prescribed dimensions.
VELUX America Inc. affirms that if a high quality alternative adhesive
underlayment, installed per our instructions, does not fail but a leak occurs
in some other VELUX skylight or flashing component due to no cause from
the alternative underlayment, then such a leak would be covered under the
terms of the VELUX "No Leak" installation warranty.
