Metro 150 Xt - instruction for installation
English
1. Introduction
The appliance is supplied in two versions, the Metro 150 XT and the Metro 150 XT tunnel.
The safe operation of the appliance is guaranteed by the use of a second thermocouple fitted to the main burner.
The Metro 150 XT is a “standard” appliance. It is always mounted against a wall. The Metro 150 XT tunnel is a “look-
through appliance”; it has a pane at the font and back.
The Metro 150 XT and Metro 150 XT tunnel are room-sealed atmospheric gas-fired heating appliances. A room-
sealed appliance does not extract the combustion air from the living environment, but from outside. This is done by
means of a combined flue gas discharge system / combustion air supply system. In this concentric system, the outer
pipe functions as the air supply and the inner pipe functions as the flue gas discharge.
This system can be installed through the wall or through the roof.
These appliances are built within a chimney breast. In order to reach a proper heat discharge, the chimney breast
must be ventilated. DRU is able to supply various ventilation elements.
The appliances are supplied with a wireless remote control that works on batteries.

6.5. Flue gas discharge / combustion air supply system
6.5.1 General
The appliance is of the C11/C31 type.
The appliance is connected to a combined flue gas discharge/combustion air supply system, hereafter referred to
as the concentric system.
The passage to the outside can be made with a wall duct (see section 6.5.2) or with a roof duct (see section 6.5.3).
If necessary, you can also use an existing discharge channel (see section 6.5.4).
N.B. - Only use the concentric system supplied by DRU (Ø130 / Ø200 mm). This system was tested in combination with the
appliance; DRU cannot guarantee a proper and safe operation of other systems and cannot accept liability for these
systems;
- For connecting to an existing chimney ue you should only use the installation set supplied by DRU.
The concentric system is constructed from (the discharge stump of) the appliance.
If structural circumstances require that the concentric system is placed first, the appliance can later be connected
with a telescopic pipe piece.

6.5.2 Application with wall duct
6.5.2.1 Construction of concentric system with wall duct
The concentric system with wall duct has to comply with the following conditions:
➠
The complete system’s diameter is 130/200 mm;
➠
First, a concentric pipe of at least 0.8 meter should be connected vertically to the appliance;
➠
The total vertical pipe length can have a maximum of 4 meters;
➠
After the vertical part a bend of 90° is connected;
➠
When using a minimum 0,8 up to maximum 4 meter vertical pipe length, the total horizontal pipe length may have a
maximum of 5 meters (wall duct not included; see Fig. 4a).
Depending on the construction of the concentric system, the appliance must receive further settings; see Table 1 for
determining the conditions and section 6.8, Adjusting the appliance, for the method.

6.5.2.2 Installing the concentric system
To install the concentric system commence as follows:
➠
Construct the system from the (connection stub of the) appliance up.
N.B. - Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and /or ceiling. If
the system will be built in (for instance) a cove, it should be fully made of incombustible material;
- Use heat-resistant insulating material for ducts made of combustible material;
- The rosette (mounting inner plate) of the wall duct is too small to seal the Ø 310 mm opening when passing through
combustible material. That is why you should rst apply a suciently large heat-resistant intermediate plate to the
wall. Then, the rosette is mounted on the intermediate plate.
➠
Connect the concentric pipe sections and the bend(s);
➠
Fit a clamping strip and silicone sealing ring to every connection;
➠
Secure the clamping strip with a self-tapping screw in places which will be inaccessible after installation;
➠
Use enough brackets to ensure that the weight of the pipes does not rest on the appliance;
➠
Determine the remaining length of the wall duct;
➠
Cut the wall duct to size;
!N.B. - Make sure that the right insertion length is maintained;
- Place the wall duct with the groove/folded seam at the top;
- Make sure the horizontal concentric pipe pieces are sloping towards the wall duct, in order to prevent rain water
from entering.
➠
Mount the rosette (mounting inner plate); if necessary, on a heat resistant intermediate plate when passing through
combustible material;
➠
Attach the wall duct from the outside with four screws in their respective holes.
!N.B. Some heat-resistant isolation materials contain volatile components that will spread an unpleasant smell for a pro-
longed time; these are not suitable.

6.5.3 Application with roof terminal
6.5.3.1 Construction of concentric system with roof terminal
When using a roof terminal, we distinguish:
- Concentric system without bends (see section 6.5.3.1.1);
- Concentric system with bends in the vertical plane (see section 6.5.3.1.2);
In section 6.5.3.1.3 it will be determined whether the concentric system is allowed and what baffle settings apply.
6.5.3.1.1 Concentric system without bends
A concentric system without bends must comply with the following conditions:
- The construction of the chosen system is allowed (for this, see section 6.5.3.1.3):
- On the appliance, at least 0,8 metre of concentric pipe with a diameter of 130 / 200 mm is initially connected
vertically;
- After the first metre the system will be reduced to a 100 / 150 mm diameter.
6.5.3.1.2 Concentric system with bends
A concentric system with bends must comply with the following conditions:
- The construction of the chosen system is allowed. (For this, see section 6.5.3.1.3);
- On the appliance, at least 0,8 metre of concentric pipe with a diameter of 130 / 200 mm is initially connected
vertically;
- Up to (and including) the last bend, the system is made with pipe pieces with a 130 / 200 mm diameter;
- After the last bend the system will be reduced to pipe pieces with a 100 / 150 mm diameter.
6.5.3.1.3 Acceptability of concentric systems with accompanying settings
Depending on the construction of the concentric system, the appliance is set by placing the baffle and/or removing
the air inlet guide.
In the following procedure you can see how the allowability of a concentric system can be determined and which
settings are needed.
➠
Determine the following data:
1) The number of bends required (no distinction is made between 45° and 90° bends);
2) The total number of meters of horizontal pipe length;
3) The total number of meters of vertical and/or sloping pipe length (roof terminal excluded).
With these data and Table 2 you will be able to determine whether the concentric system is allowed. In Table 3 you
can see which setting the appliance requires.
Follow the procedure described below:
➠
In the rst 2 columns of Table 2, look for the number of bends required and the total horizontal pipe length.
➠
In the 3rd column of Table 2, look for the total vertical and/or sloping pipe length.
If you end up in a box with the letter A, B, C, or D the concentric system chosen by you is allowed.
➠
Use Table 3 to determine which conditions apply for the bae and/or the air inlet guide (for setting, see section 6.8).
Examples
To clarify, we will give 2 examples to determine the allowability of a concentric system and the conditions for setting
the appliance.
In Table 2 the route to be followed is indicated by arrows. The result is indicated in a box with a red frame.
Example 1
1) 2 bends
2) 3 meters horizontal
3) 8 meters vertical/sloping
→ Construction of this concentric system is allowed.
→ Situation B applies for setting the appliance
Example 2
1) 3 bends
2) 4 meters horizontal
3) 9 meters vertical/sloping
→ Construction of this concentric system is not allowed.

6.9 Arranging the logs / pebbles
The appliance is supplied with a set of logs or pebbles.
N.B. Observe the instructions below precisely to avoid unsafe situations.
- only use the log/pebble set supplied;
- arrange the logs/pebbles exactly as described;
- make sure the pilot burner and the space around it are kept free from objects (see Photos 9a and 9b);
- make sure that thermocouple 2 and the space around it are kept free from objects (see Photos 10a and 10b);
- make sure that the slot between the burner tray and the tray surrounding the burner is kept free from objects.
6.9.1 Logs
The log set consists of vermiculite (see Photo 2), chippings (see Photo 3) and a few branches.
➠
Fill the burner tray with the vermiculite, spreading it out evenly.
!N.B. - You can alter the ame eect by moving the vermiculite but;
- the burner cap must remain covered by vermiculite to help preserve the useful life of the burner.
➠
Fill the tray surrounding the burner with chippings; spreading them out evenly;
➠
Identify the braches A/I using Photo 4 for reference.
!Tip The burn marks on the branches will help you identify them.
➠
Arrange branches A-E around the (main) burner (see Photos 6a and 6b):
- First lay branch A symmetrically with respect to the pilot burner;
- Continue with branches B, C, D and E.
➠
Now lay branches F and I across the burner (see Photo 7).
N.B. The branches must not cover the burner cap entirely (see Photos 5 and 8) because:
- the main burner will then not ignite properly, which could lead to unsafe situations;
