!Caution

When placing the chimney breast, you should take the following into account (see Appendix 3, fig. 2):

the location of the control hatch: this must be placed as low as possible;

the dimensions of the control hatch; see Placing the control hatch section 5.6;

the Dru control hatch is not supplied with all appliances. Nevertheless, we recommend only using a Dru
control hatch, which can be supplied separately, if necessary. If you decide not to take this option, you will
have to make a 100 cm

ventilation hole that is placed as low as possible, for the benefit of the incoming

ventilation.

the location of the ventilation holes (V) (outgoing);

maintain a minimum 30 cm distance between the top of the ventilation hole (outgoing) and the ceiling of
the house.

the measurements of the glass pane, so that it can be placed/removed after placing the chimney breast;

the protection of the gas control and the pipes against cement and plaster.

!Tip

You should preferably apply the ventilation holes (outgoing) on both sides of the chimney breast. You can use
DRU ventilation elements.

Prior to completely closing the chimney breast, check whether the discharge / concentric system is placed
correctly.

whether the channels, fixing brackets and possible clip bindings, which cannot be reached after installation,
are fastened by means of self-tapping screws.

If applicable, do not plaster on or over the edges of the construction frame, because:

the heat of the appliance could cause cracks;

it will no longer be possible to remove/place the glass pane.

When using stone-like materials and/or a plaster finishing, allow the chimney breast to dry for at least six weeks
prior to using the appliance in order to prevent cracks.

5.6 Placing the control hatch

(if applicable)

The control hatch (also see paragraphs 5.4 and 5.5) is placed as low as possible in the chimney breast.

!Caution

The bottom of the control hatch may not be placed higher in the appliance than the burner surface.

A number of components are placed in the control hatch, such as data plate, gas control, receiver belonging to the
remote control and, if applicable, the control panel of the DRU Maxvent system

or the components belonging to

the DRU Powervent system

Place the control hatch as follows; see Appendix 3, fig. 3 for details:

Make an opening in the chimney breast of 285 x 194 mm (h x w).

Place the inner frame (1); unscrew bolts (5) for this.

!Tip

When the chimney breast is made of bricks, the inner frame can be built with bricks at the same time

When using a different material, you can glue the inner frame or fix it with four flush screws.

Mount the gas control to the brackets of the inner frame (2).

Reconnect the pipes to the gas control.

!Caution

Avoid kinks in the pipes;

Tighten the flexible gas pipe and the pilot burner pipe until they are gastight.

First tighten the thermocouple by hand and;

Then tighten it a quarter turn using a suitable spanner;

The pilot burner pipe must be protected against possible corrosive influences as a result of, for example,
humidity, cement that has fallen down, dirt that has fallen down from the chimney, etc. The pilot burner pipe
should remain permanently free from the ground and the walls of the room in which the appliance is built in.

Make sure there is no dirt in gas pipes and connections.

Connect the gas pipe to the gas tap.

Bleed the gas pipe.

Place the receiver in the holder (3); for connecting, see section 6.1.

Place the data plate in its intended clamp (6).

Fix the outer frame with door (4) to the inner frame using 2 socket cap screws (5).
