INSTALLATION GUIDE – FREE-STANDING CONVECTORS

1. UNIT DESCRIPTION

A free-standing heater which uses the natural or forced
(with fan) convection heating principle. Since the heater
fully uses physical laws of thermodynamics it represents
one of the most efficient methods of interior heating.

Benefits of free-standing convectors::

High output
Silent operation when the fan is running (models

with fan)

Low hot water consumption

› Short response time

Design
Minimum requirements for operation and mainte-

nance

3. TECHNICAL PARAMETERS

Use: dry environment according to the specification.

Maximum operating pressure: 1 MPa.

Maximum operating temperature: 110 °C.

Operating medium: water. The use of other media
is prohibited. Water may not be mixed with other
substances, such as antifreeze fluids!

Environment: interiors with temperatures ranging
between +5 °C and +40 °C.

1. CONVECTOR GRILLE – a design piece on the con­vector. It must not be covered!

2. OUTER BODY OF THE CONVECTOR – aluminum
convector body with plastic covers.

3. SCREW FITTING – a valve that controls/adjusts he­ating water flow.

4. AXIAL RADIATOR VALVE – a valve used for flow
regulation.

5.

THERMOSTATIC HEAD – used for manual regulation.

6. CONNECTING SCREW FITTING – for connecting
valves; gasket (O-ring) is to be installed in it.

7. SUPPORTING FRAME OF THE CONVECTOR – sup­porting element for heat exchanger and fan (mo­dels with fan)

8. FAN – used for forced convection (model with fan).

9. CABLE GROMMET – intended for power supply ca­ble for the control unit (models with fan).

10. EB CONTROL UNIT – fan motor control unit (mo­dels with fan).

11. HEAT EXCHANGER – copper pipes with pressed-

-on aluminum fins through which the heating water
flows. The exchanger design depends on the con­vector model.

12. AIR VENT VALVE – for venting (bleeding) the con­vector heat exchanger.

4. BEFORE INSTALLATION

Select the correct convector type (with fan / wi-

thout fan) from the catalogue – see paragraph 4.1.

Select the correct convector position and location

– see paragraph 4.2.

4.1 Suitable Convector Type

Decide whether the convector will act as the main
source of heat, or an additional heating element or, if
applicable, a heat barrier.

As the main source of heat in your apartment / room,
the convector should sufficiently cover the entire ther­mal loss of the room. Therefore always choose a hea­ting unit with a capacity that is higher than the thermal
loss of your apartment, room, or other areas.

All convectors are designed for dry environment, i.e., an
environment where the average annual relative humidity
does not exceed 75 %. A wet environment is an environ­ment where such average annual value is equal to or
greater than 75 % or where the convector is exposed to
direct contact with water. In terms of convector selection,
a dry environment is in general any environment where
no precipitation of vapor occurs in the convector unit.

4.2 Convector Position

The free-standing convector made by MINIB is to be
floor-mounted. Place the convector so that it does not
disturb the overall aesthetic experience of the room.
We recommend leaving a 50-150 mm space between

the convector and the wall – Figure 2. Never cover
the top grille – this would result in flow reduction and
a considerable decrease in the convector output.

5. INSTALLATION

Free-standing convectors are designed for installati­on on the floor. Please read the following instructions
before you start.

For floor installation use the template to plan the

exact position of the inlet/outlet heating water
pipe, mounting points (in models with fan) of the
power supply (cable).

Fix the free-standing convector using the mounting

accessories supplied by MINIB a.s..

A correctly installed convector is in horizontal po-

sition and fixed in the full width of the leg.

7. VENTING THE UNIT

Vent (bleed) the unit using the air vent valve during
the first use as necessary. In free-standing convec­tors, the air vent valve is located on the opposite side
of the water inlet/outlet side on the heat exchanger.

For additional options see the catalogue or visit:
http://www.minib.com/

6. CONNECTION OF THE FITTINGS

Connect the fittings using the supplied standard ac­cessories.

The axial radiator valve is connected to the water in­let point into the convector. The control screw fitting
is installed on the outlet pipe. Insert the O-rings be­tween the axial radiator valve / control screw fitting
and the heat exchanger. Use gaskets for all the other
connections.

FIG. 6: Drill the holes, install the heating water inlet and return

pipes, and the power supply cable in models with fan.

FIG. 3: For all models. Loosen the screws (do not remove the

screws completely!) on both legs of the convector body and
remove the top cover, the plastic covers, and the grille.

FIG. 8: For all models. Fix the convector frame using screws.

FIG. 13: For all models. Connect the thermostatic head.

FIG. 12: For all models. Tighten the screws on the convector

the fittings – see paragraph 6. Check tightness of the con­nections. The inlet is to be equipped with the axial valve. The
control screw fitting is to be used on the outlet pipe.

FIG. 10: For models with fan. Connect the cable through the

grommet to the control unit according to the instruction and
the control type selected. Check function of the fan.
