ROOFMASTER STEF and STOF
The STEF and STOF roof fans are used as exhaust
fans in ventilation systems. The roof fan can be
mounted either on a BOGA roof duct, STEZ-01 flat
roof socket or STEZ-07 sound attenuator or on a
chimney built at site with help of MORA or STEZ-03
mounting frame. The fan section is supported by
hinges on one edge of the base plate and can be
raised and locked in fully open position for cleaning.
Fig. 1
To mount the STEF/STOF on the BOGA roof duct
(or STEF on the STEZ-01/STEZ-07)
1. Fit the sealing strip to the top edge of the roof duct as
shown in Figure 1.
2. Lift the STEF or STOF 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
flanges (tapped holes) using the four M8x35 screws
supplied with the fan.
To mount the STEF on a chimney built on site
(or on EI60/EI120 BOGA) with help of mounting frame
MORA/STEZ-03.
(If the chimney has exactly the same dimensions as
the BOGA roof duct, no mounting frame will be required,
i.e. the fan can be mounted as described in the
preceding chapter).
1. Fit the sealing strip to the chimney as shown in the
Figure 2.
2. Carefully mount the mounting frame on the chimney
securing it with four screws or wedge anchors.
The mounting frame has four 12 mm dia. holes for the
mounting screws. (The joint must bear the wind
load when the roof fan is opened for chimney
sweeping). Make sure that the location of the safety
isolation switch and the direction of the hinges are
appropriate.
3. Fit the sealing strip to the upper edge of the mounting
frame as shown in Figure 2.
4. Lift the roof fan onto the mounting frame and secure
it as described above in Pos. 3 “To mount the
STEF/STOF on the BOGA roof duct”. See Figure 2.
