Orientation of the equipment should be north facing and free of shading from trees or other structures.
The equipment is fitted with a thermostat set to 30°C. The fan will not operate if the air temperature at the thermostat
is below 30°C. This thermostat will prevent operation in winter months reducing venting of roof heat.
Any additional flashing use during installation of this equipment must comply with AS/NZS 4020 “Testing of products
for use in contact with drinking water”.
Roof rafters must not be interfered with during this installation. If a rafter is required to be cut, please seek advice from
a certified building professional.
NOTE
– The following installation instructions are offered as a guide only due to the diversity of roof types and profiles.
Solavent attic fans should be installed by suitably qualified persons who can decide on the best installation method for
your roof top.
METAL ROOF TOP INSTALLATION
1.
Prior to installation of this equipment, use the cardboard wrapping to cover the solar cell to prevent fan operation
during installation. Secure the wrapping to the equipment with tape. Remove the cardboard as the final installation
action. The fan blade may pose a laceration risk should it operate during the installation process.
2.
Locate the Solavent carefully on the roof top. It should be positioned so that the higher horizontal edge is located under
the ridge cap to ensure against water ingress.
3.
NOTE
- Try to locate the Solavent horizontally between roof rafters
4.
NOTE
– Locate the Solavent such that there is even overlap of the vertical edges over the peaks of the corrugations so
that these edges can be effectively sealed against water ingress.
5.
Remove the screws from the section of ridge cap to be used and keep these screws.
6.
Use the 540mm x 540mm cardboard template to mark the position of the Solavent and the 400mm diameter area of the
roof to be removed. Mark these mounting positions on the roof top using a permanent marker.
7.
Use an appropriate cutting tool such as tin snips and remove the 400mm diameter section of metal
roof. Ensure correct protection including gloves and eye protection is used during this process.
Remove any insulation from this section if required.
8.
You may wish to fasten a batten under the roof to along the line of the bottom edge of the Solavent
to fasten the roofing screws to. This would be more of a consideration in high-wind areas.
9.
Apply generous beads of a high quality roof and gutter silicon to the roof corrugation peaks inside of the marked area
on the roof top and gently tilt and slide the Solavent up under the ridge cap setting it down onto the silicone beads.
10.
Re-insert the roofing screws through the Solavent and ridge cap of the roof using roofing screws removed at the
commencement of the installation. Note that at least two roofing screws should be used. If screws are old or corroded,
they should be replaced.
11.
Contoured bitumen impregnated foam, available from most major hardware chains, should be inserted across the full
span of the bottom horizontal edge of the Solavent to protect against any wind driven rain or splash backs into the roof
cavity and to prevent ingress by insect and small animals. The contoured foam is pre-formed and effectively fills the
gaps in the valleys of the corrugated iron roof.
12.
The two vertical edges and lower edge can now be fastened to the roof using suitable self-drilling roofing screws. A
minimum of six additional roofing screws should be used. If the pre-drilled holes in the base of the Solavent do not line
up with the peaks of the roof, ignore these holes however fill with silicon.
13.
NOTE
– ONLY fasten roofing screws to peaks of corrugations. Insert silicone into holes before fastening with roofing
screws. Insert silicone into any unused pre-drilled holes in the Solavent base plate.
14.
Do a final inspection and use silicon around any the edges of the Solavent base and any other gaps that are evident.
15.
Remove the cardboard cover from the PV panel and the Solavent will now be fully operational
