1. Introduction
The Metro 100 XTL is a room-sealed atmospheric gas-red heating appliance.
This version of the Metro 100 XTL is suitable for natural gas. The safe operation of the appliance is guaranteed by the
use of a second thermocouple tted to the main burner.
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 ue 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 ue gas discharge.
This system can be installed through the wall or through the roof.
These appliances are built within a chimney breast. For this, DRU has a number of chimney breasts in its range.
In order to reach a proper heat discharge, the chimney breast must be ventilated. DRU is able to supply various
ventilation elements.
The adjustable height of the appliance can be increased by means of the extension legs that can be ordered from
DRU.
The appliances are supplied with a wireless remote control that works on batteries.

6.5.2.2 Placing concentric system with wall terminal
Caution - Maintain a distance of at least 50mm between the outside of the concentric system and the walls and/or the ceiling.
If the system is built in (for instance) a cove, it should be made with non combustible material all around it.
- Use heat-resistant insulation material when passing through combustible material;
- The rosette (mounting inner plate) of the wall terminal is too small to seal the Ø250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.
!Caution Some heat-resistant insulation materials contain volatile components that will spread an unpleasant smell for a pro-
longed time; these are not suitable.
Place the concentric system as follows:
➠
Build the system up from (the connection stump of) the appliance.
➠
Connect the concentric pipe pieces and the bend.
➠
On each connection, apply a clip binding with silicon sealing ring.
➠
Use a self-tapping screw to x the clip binding to the pipe on locations that cannot be reached after installation.
➠
Apply sucient clamps, so that the weight of the pipes does not rest on the appliance.
➠
Determine the remaining length of the wall terminal;
➠
Make sure the wall terminal has the right dimensions.
!Caution - Make sure that the right insertion length is maintained;
- Place the wall terminal with the groove/folded seam at the top;
- Make sure the horizontal concentric pipe pieces are sloping towards the wall terminal, 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 terminal from the outside with four screws in their respective holes.
