Important Guidance for the Republic of Ireland
(Note: Varisol Collectors are not NSAI agrement compliant.) Solar installations in the Republic
of Ireland must be installed in accordance with the Irish Agrément Board certificate No. 10/0345,
which takes precedence over this installation document.
NSAI Agrément (Irish Agrément Board) is designated by Government to issue European Technical
Approvals.
NSAI Agrément Certificates establish proof that the certified products are ‘proper materials’
suitable for their intended use under Irish site conditions and in accordance with the Building
Regulations 1997 to 2011.
Certificate No. 10/0345 details the installation requirements and extends to every aspect of
the installation. NSAI Agrement compliant roof kits are supplied with their own installation
instructions, not contained in this manual, also available upon request.
Agrement compliant roof kits are available including joist hangers for the additional roof supports
required.
Readers are advised to check that this Certificate has not been withdrawn or superseded by
contacting NSAI Agrément, NSAI, Santry, Dublin 9 or online at:
