1. Introduction
The Trio is a freestanding atmospheric gas heating appliance. This version of the Trio 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 Trio is a closed appliance. A closed appliance does not extract the combustion air from the living environment,
but from outside. This is done through a combined flue gas discharge system / combustion air supply system. In
this concentric system the outer pipe serves as air supply and the inner pipe as flue gas discharge.
This system can be installed through the wall, or through the roof.
The concentric system can be supplied in the colour of the appliance.
The appliance is supplied with a wireless remote control that works on batteries.
2. CE Declaration
Internal precautions at the company will guarantee that appliances produced by DRU comply with the essential
requirements of the regulation concerning gas combustion appliances and the standards applied for that purpose.
This declaration will lose its validity if adjustments are made to the appliance, without prior written permission by
DRU. A copy of the CE test certificate can be downloaded via www.druservice.com.

6.5 Flue gas discharge / combustion air supply system
6.5.1 General
The appliance is of the C11/C31/C91 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).
Caution
- 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.
!Tip
DRU does not recommend placing the telescopic piece, because this visible pipe piece cannot be supplied in colour
and does not really combine well with the appliance.
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 Appendix 4, Fig. 2):
- First, a concentric pipe of at least 1 meter should be connected vertically to the appliance;
- The total vertical pipe length can have a maximum of 4 meters;
- On the vertical part a bend of 90° is connected;
- The total horizontal pipe length can have a maximum of 3 meters (wall duct excluded).
Under these conditions you should not install the restrictor slide; the air inlet guide will not be placed.
6.5.2.2 Placing concentric system with wall duct
Place the concentric system as follows:
Build the system up from (the connection stump of) the appliance.
➠
Caution
- Maintain a distance of at least 50 mm between the outside of the concentric system and the walls and/or the ceiling;
- Use heat-resistant isolation material when passing through 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.
!Caution
Some heat-resistant isolation materials contain volatile components that will spread an unpleasant smell for a pro-
longed time; these are not suitable.
