Roofmaster STEF and STOF
The STEF and STOF power roof ventilators are
used as exhaust air fans in ventilation installations.
The ventilator 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, fitted with
the 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 STEZ-01/STEZ-07)
1. Fit the sealing strip supplied, to the top edge of
the roof duct as shown in Figure 1.
2. Lift the STEF or STOF power roof ventilator onto
the roof duct. Use the lifting lugs supplied, if
necessary. See Figure 1.
Make sure that:
– the ventilator base plate is seated over the edges
of the chimney duct. Do not damage the sealing strip.
– the safety isolating switch on the ventilator and
that the cable gland on the roof duct are on the same
side. This determines the position of the hinges.
See Figure 1.
3. Secure the power roof ventilator via its base plate
to the roof duct flanges (tapped holes) using the four
M8 x 35 screws supplied in the bag of accessories.
To mount the STEF on an in-situ built chimney
with the MORA (STEZ-03) mounting frame.
(If the chimney has exactly the same dimensions
as those of the BOGA roof duct, no mounting frame will
be required, i.e. the ventilator can be mounted as
described in the preceding instruction.)
1. Fit the sealing strip, supplied, to the chimney
as shown in Figure 2.
2. Carefully mount the MORA mounting frame on
the chimney securing it with the four screws supplied
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 power roof
ventilator is opened for chimney sweeping.)
Make sure that the location of the safety isolating
switch and the direction of the hinges are
appropriate.
3. Fit the sealing strip, supplied, to the upper edge of
the mounting frame as shown in Figure 2.
4. Lift the power roof ventilator onto the mounting
frame and secure it as described in item 3 under the
heading “To mount the STEF on the BOGA roof
duct”. See Figure 2.

Electrical wiring
(To be carried out by an authorised electrician.) The
wiring diagrams are on page 5 The wiring diagrams for
the speed controllers (STYR), are included in the supply.
A. Power roof ventilator with SAFE safety isolating
switch, Figure 3.
If the STEF power roof ventilator has been equipped
with a factory-fitted SAFE safety isolating switch, the
electrical wiring between the motor and safety isolating
switch has already been done at the factory. The safety
isolating switch has been mounted in a recess in the
side of the ventilator casing. Only the front section of the
switch is exposed.
1. Open the safety isolating switch protective cover.
2. Open safety isolating switch cover.
3. Run the flexible power supply cable through the
cable seal at the lower edge of the ventilator casing
to the safety isolating switch. Adjust the length
of the electric cable so that sufficient slack will be
available for raising the fan for servicing.
4. Wire the connections, close the safety isolating
switch and the cover.
5. Check to make sure that the switch functions
correctly.
NB. In case of spark-proof version, the safety
isolation switch shall not be mounted in the fan
casing. If the spark-proof roof ran is ordered with
safety isolation switch, it is mounted externally
on the fan casing.
B. Power roof ventilator with a safety isolating switch,
which is to be fitted at the building site.
If the power roof ventilator has not been equipped with a
factory-fitted safety isolating switch, fig. 4, the safety
isolating switch can be mounted at an optional location,
for example in the side of the roof duct or in the side of
the power roof ventilator.
1. Mount the safety isolating switch at the desired
location.
2. Wire the connections inside the safety isolating
switch.
3. Open the connection cover on the side of the power
roof ventilator. To facilitate the electric connection
open the roof of the power roof ventilator and pull up
the insulated cover plates of the motor.
4. Open the junction box on the electric motor.
5. Run the flexible power supply cable through the
cable seal at the lower edge of the ventilator casing
to the connection opening and then to the motor.
Adjust the length of the electric cable so that sufficient
slack will be available for raising the fan for servicing.
6. Make the electrical connections to the motor.
7. Mount the panels and the top grille.
8. Close the junction box in the switch and make sure
that the safety isolating switch functions correctly.

Maintenance
Under normal operating conditions, the power roof
ventilator does not require any maintenance. If the
ventilator is used for extracting air from polluting
environments, such as kitchens, the impeller and the fan
casing must be cleaned to remove impurities, if any,
deposited on their surfaces. All local regulations must
be complied with.
Spark-proof version: the impeller and the motor must
be checked at least once a year to guarantee problem-
free operation.
To clean the fan impeller, casing and duct.
1. Isolate the power roof ventilator from the mains
power supply by opening the safety isolating switch.
2. To facilitate the opening of sizes 5, 6 and 7,
the handles (included in delivery) can be used.
The handles are mounted to the casing as shown
in Figure 6.
3. Back off the arresting screws about 10 mm,
so that the fan section can be raised on its hinges.
The stay rod (1 or 2 stay rods depending on the
size of ventilator) locks the fan section automatically
in the fully open position as shown in Figure 5.
4. Make sure that the stay rod has become locked
properly in the open position and that the mounting
of the ventilator base plate and mounting frame
are in good condition.
5. Clean as required. The sound insulated fan casing
surfaces can also be cleaned since the insulation is
protected by perforated sheet metal.
6. On having completed the servicing work, release
the stay support by depressing the locking lever (see
Figure 5) and lower the fan section back to its
initial position. Re-tighten the arresting screws. The
fan casing can also be cleaned from the top after
opening the top grille.
To change the motor and the fan impeller
1. Isolate the power roof ventilator from the mains
power supply by opening the safety isolating switch.
2. Open the top grille on the power roof ventilator
and remove the panels.
3. Raise the fan section as you do for cleaning, see
items 2 and 3 above.
4. Open the end plate of the fan impeller and prise
the impeller off the motor shaft. Note! It is advisable
to cover the chimney opening before doing
the dismantling, so that parts and tools will not
inadvertently fall down the chimney.
5. Lower the fan section, remove the electrical
cables from the junction box and remove the fan
from its mounting plate.
6. Mount a new motor and fan impeller in the reverse
order.
7. Close the power roof ventilator, start it and listen
making sure that no abnormal sound or vibration is
generated by the power roof ventilator.
