Complies with BS5250 2011 the Code of Practice for control of condensation in buildings

Installation Advice
Designed to fit between 38mm thick trussed rafters or ceiling joists spaced 600mm centres to provide a clear joist opening width of 562mm
If the roof design does not provide this joist opening width, a suitable opening must be formed
Trimmers must be installed across the ends of a frame; these should be spaced to give a clear opening length of 665mm
The frame fixes ten screws (supplied) - three through each side and two through each end
Do not over tighten the fixing screws as this could distort the screws
Fit the loft access door after the ceiling has been plaster boarded and skimmed
The frame must be a good fit into the trimmed opening, never force it into an opening that is too small, if the opening is too large use packers to ensure a good fit
