|---|---|
I. METAL ROOF INSTALLATION
STEP 1
Study the figure to assess how many solar roof exhaust fans you need and where
to install them for your home or business. To work out where to position the
fan, you need to consider any afternoon shade on the roof during the warmer
months. A well-positioned fan should allow the solar panel to receive sun from
the south (north for the southern hemisphere) and west during the warmer
months.
GUIDE
A – 1x solar fan up to 1,000 sqft place
B – 2x solar fans up to 2,000 sqft place
C 3x solar fans up to 3,000 sqft place
Note: Shade will affect the fan performance. Number of fans needed may
vary depending on the situation.
STEP 2
Remove 2 ridge capping screws and slide the top edge of the flashing up under
it as shown in the figure. It is important to position the lashing, so it does
not cover any roofing screws. The roofing screws running from the top to the
bottom of the roof are where the rafters are located.
Once positioned, mark a circle on the inside edge of the flashing.
STEP 3
Following the circle marked on the roof cut an opening in the roof as shown,
using a metal blade saw or tin snips. If there is any foil under the metal
sheets, cut a cross in the foil and fold back the corners.
Note: Take care not to cut into any battens/rafters under the roof sheet
when cutting.
STEP 4
Slide the flashing back up under the roof capping, refit the 2 ridge capping
screws through the flashing, and bend the edges of the flashing down on the
left and right sides to create a tight fit with the roof. Next , use tin snips
to cut notches in the flashing’s bottom to suit the corrugations of the roof
and bend the notches down. Next, apply silicone bonded to the edges’ underside
and outside. After this, use silicone bonded to the underside and outside of
the bottom section of the flashing.
Note: Don’t apply silicone to the valleys at the bottom of the flashing.
STEP 5
As shown in the figure here, use a minimum of 8 and a maximum of 12 tech or
roof screws with rubber seals along the left, right, and bottom of the
flashing to secure the roof.
Note: Tech screws and roofing screws are not included.
STEP 6
Place the main body of the fan over the flashing as shown below. Turn the main
body of the fan left or right to suit the direction required for the solar
panel.
Tip: Position the solar panel between the south (north for the southern hemisphere) and west to best suit the sun in warmer months.
STEP 7
Using a powered screwdriver, screw at least 4 small tech screws through the
pre-drilled holes in the fan’s main body into the flashing, as shown below.
Tip: You may not get the top tech screw in place, as the roof angle may prevent this. In this case, you can screw the tech screw into another section where the main body is over the flashing.
STEP 8
You can now adjust the angle of the solar panel to receive maximum sun
especially during the midday of the warmer months as shown in the figure. As
the pitch of many roofs is already at a good angle for the summer sun, you may
just be able to leave the panel in the down position as it is supplied from
the factory, without doing anything.
To adjust the angle of the solar panels up, just adjust the 2 arms to the
correct angle and tighten the screws.
Note:
An installation option is to fit the fan under the eave vents to the side of
the house that is cool in the afternoon.This will allow the cooler outside air
to be drawn into the roof space. These are especially required when the roof
has foil under the tiles, but regardless eave vents will improve airflow.
II. TILE ROOF INSTALLATION
STEP 1
Study the figure to assess how many solar roof exhaust fans you need and where
to install them for your home or business. To work out where to position the
fan, you need to consider any afternoon shade on the roof during the warmer
months. A well-positioned fan should allow the solar panel to receive sun from
the south (north for the southern hemisphere) and west during the warmer
months.
GUIDE
A – 1x solar fan up to 1,000 sqft place
B – 2x solar fans up to 2,000 sqft place
C – 3x solar fans up to 3,000 sqft place
Note: Shade will affect the fan performance. Number of fans needed may
vary depending on the situation.
STEP 2
Remove the third tile counting down from the ridge capping (top of the roof)
as shown in the figure. Remove one complete tile from the roof. You may also
push the tile directly above the removed tile slightly up to make the opening
larger if necessary.
Ensure you discard this removed tile. Do not leave it on the roof.
STEP 3
Lift the tiles above the tile opening, slide the flashing into place as shown
here, and then push the tiles back down. This will mold the flashing to the
tiles.
STEP 4
Fit a minimum of one rafter/batten strap (2 are supplied) as shown. The strap
folds over the circular ridge on the flashing and it can either be screwed or
nailed through the rafter/batten strap into the rafter or batten.
Note: Rafters run from the top of the roof down to the facial and battens
run across the roof directly under the tiles.
STEP 5
Once the flashing fitting is complete, run a bead of clear silicone along the
top of the flashing that joins with the upper tiles.
STEP 6
Place the main body of the fan over the flashing as shown below. Turn the main
body of the fan left or right to suit the direction required for the solar
panel.
Tip: Position the solar panel between the south (north for the southern
hemisphere) and west to best suit the sun in warmer months.
STEP 7
As shown in the figure, using a powered screw-driver, screw at least 4 small
tech screws through the pre-drilled holes in the fan’s main body through into
the flashing.
Tip: You may not get the top tech screw in place as the angle of the roof may prevent this. In this case, you can simply screw the tech screw into another section where the main body is over the flashing.
STEP 8
You can now adjust the angle of the solar panel to receive maximum sun
especially during the midday of the warmer months as shown in the figure. As
the pitch of many roofs is already at a good angle for the summer sun, you may
just be able to leave the panel in the down position as it is supplied from
the factory, without doing anything.
To adjust the angle of the solar panels up, just adjust the 2 arms to the
correct angle and tighten the screws.
STEP 9
Now that the primary installation is complete, you can mold the flexible
flashing to suit your tiles and bend the bottom section down to allow water to
run off onto the tiles below. Then run a bead of silicone along the left and
right sides of the flashing and your job is complete.
Note:
An installation option is to fit the fan under the eave vents to the side of
the house which is cool in the afternoon. This will allow the cooler outside
air to be drawn into the roof space. These are especially required when the
roof has foil under the tiles, but regardless eave vents will improve airflow.
