ROOFMASTER STEF and STOF
Fig. 1
To mount the STEF on the BOGA roof duct
1. Fit the sealing strip to the top edge of the roof duct as
shown in Figure 1.
2. Lift the STEF
roof fan onto the roof duct.
Use the lifting lugs for the larger sizes if necessary.
See Figure 1.
Make sure that:
– the fan base plate is seated over the edges of the
roof duct. Do not damage the sealing strip.
– the safety switch and the cable gland in the roof duct
are on the same side. This determines the position
of the hinges. See Figure 1.
3. Secure the roof fan via its base plate to the roof duct
anges (tapped holes) using the four M8x35 screws
