METRO 70 - INSTRUCTION FOR INSTALLATION
English
1. Introduction
The appliance is available in two models, the Metro 70 and the Metro 70 Tunnel. This version of the Metro 70 and
the Metro 70 Tunnel is suitable for natural gas. It is not possible to make the appliance suitable for a different type of
gas by using a so-called conversion set. The Metro 70 is a ‘standard’ gas fire and should always be installed against
a wall. The Metro 70 Tunnel is just that, a ‘tunnel fire’ with both a front and back window.
The Metro 70 and the Metro 70 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 sup-
plies 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.

6.5 Flue / combustion air supply system
6.5.1 General
The appliance is type C11/C31.
The appliance is connected to a combined flue/combustion air supply system, from here on referred to as the
concentric system.
It is also possible to use an existing duct.
N.B.: Only use the concentric system (Ø 100/150mm) and related accessories supplied by DRU. The system has been appro-
ved along with the equipment. Where non-DRU systems are used, DRU cannot guarantee or accept any responsibility
for the proper and safe working of the same.
The concentric system is constructed from the appliance up.
If, for structural reasons, the concentric system is fitted first, the appliance can be connected later using a piece of
telescopic pipe.
An equipment can be fitted with a wall duct (please refer to 6.5.2) or a roof duct (please refer to 6.5.3).
6.5.2 Installation with a wall duct
6.5.2.1 Constructing the concentric system
The settings of the equipment are made in the factory with a 1 to 4 meter vertical pipe + 90° pipe bend + wall duct.
In such case, the system does not require any further adjustments. If your situation is not as described above, you
should remove the air inlet guide as mentioned in 6.8.2.
Always start with a vertical pipe on the equipment. You may begin with a vertical pipe of at least 0.5 meter and a
maximum of 4 meters.

N.B.: Please note that if you install a 0.5 meters vertical
pipe on the equipment, the length should not exceed
2 meters.
The air inlet guide should be removed (see 6.8.2).
(See the example in Fig. 4a).
N.B.: Please note that if you install a 1 to max. 4 meters
vertical pipe on the equipment, the maximum ho-
rizontal length should not exceed 3 meters. The air
inlet guide should be removed (see 6.8.2) (see the
example in Fig. 4b)
6.5.2.2 Installing the concentric system
To install the concentric system commence as fol-
lows:
➠
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 instan-
ce) a cove, it should be fully made of inammable
material;
- Use heat-resistant insulating material for ducts
made of combustible material.
➠
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;
➠
Fit the wall duct with the bead//double edge at the top.
!N.B. Be sure to maintain the correct insertion length.
N.B. Mount the wall duct onto a heat-resistant plate for use with a wall duct made of combustible material.
➠
Fix the wall duct with four screws in the appropriate holes.
!N.B. Fit the horizontal concentric pipe sections sloping towards the wall duct to stop rain getting in.
6.5.3 Use with a roof duct
6.5.3.1 Constructing the concentric system
A concentric pipe of at least one meter should first be connected vertically to the equipment. The baffle and/or air
inlet guides will be adjusted according to the structure of the concentric system.
You may proceed as follows:
1. Determine the number of pipe bends required (no distinction is made between 45° and 90° pipe bends).
2. Determine the horizontal pipe lengths in meters.
3. Determine the vertical/ sloping pipe lengths (without roof ducts) in meters.
With this data, you can check using the Table 1, whether the drain system is permissible and the adjustments specific
to the same. The table functions as follows: in the first 2 left columns, search for the number of the pipe bends and
the horizontal length and in the 3 column, search for the vertical/ sloping length, after which you will arrive at the
letter A, B or C. Thereafter, click in Table 2 to find out the instructions relating to the air inlet guide and baffle (for
installation / removal, see 6.8).

➠
Check that button A on the gas control block is set to ON;
➠
Check that the space round the pilot is free;
➠
Check that the logs/pebbles have been arranged correctly.
➠
Resolve any of the above as necessary.
➠
Test the main burner 5 times to ensure it is working properly.
8.4 Flame effect
The flame effect cannot really be assessed until the fire has been on for several hours. Volatile elements in paint,
materials, etc., which evaporate during the first hours of use, will initially influence the flame effect.
!N.B. If the chimney breast is made of stone-like materials or has been nished in stucco, it should be left to dry for at least
6 weeks prior to taking it into operation, in order to prevent cracks.
➠
Check that the ame eect is symmetrical.
An asymmetrical flame effect could be caused by:
- volatile substances evaporating;
- incorrectly arranged logs/pebbles.
➠
Rearrange the logs/pebbles as necessary.
