1. Introduction
The appliance is available in two models, the Metro 130 and the Metro 130 Tunnel.
This version of the Metro 130 and the Metro 130 tunnel is suitable for use with propane. The safe operation of the
appliances is guaranteed by the use of a second thermocouple fitted to the main burner.
The Metro 130 is a ‘standard’ gas fire and should always be installed against a wall. The Metro 199 Tunnel is just that,
a ‘tunnel fire’ with both a front and back window.
The Metro 130 and the Metro 130 Tunnel are closed decorative fires. A closed tunnel draws its combustion air from
outside and not from the living area. This is done by way of a combined system that discharges the flue gases and supplies the combustion air. In this concentric system the outer pipe serves as air supply and the inner pipe as the flue.
This system can be installed through either the outer wall or the roof.
The appliances are built into a chimney breast. The DRU product range includes several chimney breasts.
The chimney breast must be well ventilated to ensure a good heat distribution. DRU can supply various ventilation
elements.
The appliances are supplied with a wireless, battery-operated remote control.

➠
Secure the appliance against the wall using the wall brackets and rawplugs supplied (see Fig. 3).
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 (Ø100 / Ø150 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 (see Fig. 4):
- First, a concentric pipe of at least 0.8 meters should be connected vertically to the appliance;
- The total vertical pipe length may have a maximum of 4 meters;
- A 90° bend is connected to the end of the vertical part;
- The wall duct is connected directly to the 90° bend (i.e. no horizontal part).
When using this configuration you must remove the air inlet guides (see Section 6.8, Adjusting the appliance); the
baffle is not fitted.
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 250 mm opening when passing through
combustible material. That is why you should rst apply a suciently 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 main-
tained;
- 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 duct
6.5.3.1 Construction of concentric system with roof duct
The concentric system with roof duct has to comply with the following conditions
➠
The construction of the chosen system has to be allowed. (See the procedure described below);
➠
First, a concentric pipe of at least 1 meter should be connected vertically to the appliance.
Depending on the construction of the concentric system, the appliance is set by placing the baffle and/or removing
the air inlet guides.
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 (wall duct not included).
With these data and Table 1 you will be able to determine whether the concentric system is allowed.
In Table 2 you can see which setting the appliance needs.
Follow the procedure described below:
➠
In the rst 2 columns of Table 1, look for the number of bends required and the total horizontal pipe length;
➠
In the 3rd column of Table 1, look for the total vertical and/or sloping pipe length.
If you end up in a box with the letter A, B, or C, the concentric system chosen by you is allowed.
➠
Use Table 2 to determine which conditions apply for the bae and/or the air inlet guides (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 1 the route to be followed is indicated by arrows. The result is indicated by a box with a red border.
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) 10 meters vertical/sloping
→ Construction of this concentric system is not allowed.
